Scapular Body

Background: Scapula is a small irregular-shaped flat bone, which may suffer from a variety of tumors or tumor-like lesions. Because the imaging manifestations are complex and changeable, correct imaging diagnosis is difficult. Introduction: At present, there are few related radiology literatures, and it is necessary to fully analyze the imaging signs of different types of benign and malignant tumors in scapula to guide clinical treatment. This study was to investigate clinical and imaging presentations of tumors and tumor-like lesions in the scapula so as to increase the diagnostic accuracy of diseases in the scapula. Methods: Patients with scapular tumors confirmed by pathology were enrolled. The imaging and clinical data were analyzed. Result: Among 108 patients, benign tumors were in 53 (49.1%) cases, intermediate in seven (6.5%), and malignant in 48 (44.4%) involving 16 diseases. Osteochondroma was the first benign tumors in 45 cases accounting for 84.9% of all benign scapular tumors followed by chondroma in four cases (7.5%). The intermediate tumors were mainly eosinophilic granuloma in four cases. Metastatic tumors were the commonest malignant tumor (27 cases or 56.2% of all malignant tumors), followed by chondrosarcoma (in 13 cases). Except for the one case of chondroblastoma in which the lesion involved the glenoid cavity, all the other cartilaginous tumors were located in the scapular body and processes. The type of lesions in the bony processes is the same as in the scapular body, the common lesions in the central area of body were malignant tumors, and the commonest lesions in the glenoid area were metastasis. Common imaging features of malignant scapular tumors were ill-defined margins, cortical destruction and soft tissue involvement. The imaging features of chondrosarcoma lack specificity except calcification. Benign lesions usually had clear boundary and marginal sclerosis. Conclusion : A wide variety of benign and malignant tumors may occur in the scapula with mostly cartilaginous and metastatic tumors, and the location and distribution of lesions are similar in the scapula to those in the long bones.

Background: The clinical and imaging presentations of primary tumors and tumor-like lesions in the clavicle are not clear. Objectives: To investigate the clinical and imaging presentations of primary tumors and tumor-like lesions in the clavicle for better diagnosis. Patients and Methods: Patients with clavicular diseases between 1963 and 2018 confirmed by pathology who had plain radiography, computed tomography (CT) scan and magnetic resonance imaging were enrolled. The age, sex, imaging data, radiological signs and location of the tumor at the clavicle of patients were analyzed and compared. Results: Eighty-one patients with clavicular diseases were identified including 49 males and 32 females with an age range of 2 - 76 years (mean, 42.6). There were malignant tumors in 50 cases (61.7%), intermediate in 12 (14.8%), and benign in 19 cases (23.5%). Malignant tumors included metastatic tumors in 31 cases (38.3%), plasma-cell myeloma in ten (12.3%), and osteosarcoma in four (4.9%). The intermediate bone tumors were mainly eosinophilic granuloma in six cases (7.4%), and aneurysmal bone cyst in three (3.7%). Benign tumors were mainly osteochondroma (6.2%), bone cyst (3.7%), and chondroma (3.7%). Malignant tumors had bone destruction, periosteal reaction, ill-defined margins and soft tissue masses. Benign tumors and tumor-like lesions had well-defined margins. Conclusion: Many tumors may occur at the clavicle with more malignant than benign tumors with no specific imaging features in most lesions. A lesion near the sternal end with atypical benign imaging features should be considered as malignant.

Abstract Tumors of the heart and the great vessels are very rare disease, and there are many disorders such as tumors originated from the heart and great vessels, metastatic tumors, and tumor-like lesions which do not fit into the usual concept of tumor or neoplasm; thus, it is very difficult to classify these tumors. We proposed a new classification of cardiovascular tumors for clinical use based on the accumulated biological analyses and clinical data of the reported literatures and our own study as benign tumors, malignant tumors, ectopic hyperplasia/ectopic tumors/others, and tumors of great vessels, with reference to the series of Atlas of tumor pathology of the Armed Forces Institute of Pathology and the recent World Health Organization classification of cardiac tumors issued in 2004. More than 50 disorders have been reported as tumors originated from the cardiovascular system, and various metastatic tumors from nearby organs, distant lesions, and intravascular extension tumors to the heart were reported. Based on the new classification, we reviewed epidemiology and incidence of cardiovascular tumors. Metastatic tumors are more frequent than tumors originated from the heart and great vessels, and cardiac myxoma is the most frequent tumors in all cardiac tumors.

Abstract Background Focal lesions of the kidney comprise a spectrum of entities that can be broadly classified as malignant tumors, benign tumors, and non-neoplastic lesions. Malignant tumors include renal cell carcinoma subtypes, urothelial carcinoma, lymphoma, post-transplant lymphoproliferative disease, metastases to the kidney, and rare malignant lesions. Benign tumors include angiomyolipoma (fat-rich and fat-poor) and oncocytoma. Non-neoplastic lesions include infective, inflammatory, and vascular entities. Anatomical variants can also mimic focal masses. Main body of the abstract A range of imaging modalities are available to facilitate characterization; ultrasound (US), contrast-enhanced ultrasound (CEUS), computed tomography (CT), magnetic resonance (MR) imaging, and positron emission tomography (PET), each with their own strengths and limitations. Renal lesions are being detected with increasing frequency due to escalating imaging volumes. Accurate diagnosis is central to guiding clinical management and determining prognosis. Certain lesions require intervention, whereas others may be managed conservatively or deemed clinically insignificant. Challenging cases often benefit from a multimodality imaging approach combining the morphology, enhancement and metabolic features. Short conclusion Knowledge of the relevant clinical details and key imaging features is crucial for accurate characterization and differentiation of renal lesions.

ObjectiveThe objectives were to evaluate the risk of malignant adnexal tumors in women with nongynecologic malignancies and to identify variables associated with the risk of malignant adnexal tumors.MethodsThe eligibility criteria included the diagnosis of a nongynecologic malignancy and adnexal tumors, which were resected or subjected to biopsy at our institute between 1999 and 2010. The risk of malignant adnexal tumors was assessed by dividing the number of patients with metastatic tumors to the adnexa or primary adnexal cancers by the total number of patients. The association of clinicopathologic variables with the risk of malignant adnexal tumors was evaluated using the Fisher exact test and binary logistic regression analysis. In patients with metastatic tumors to the adnexa, the association of clinicopathologic variables with overall survival after adnexal surgery was examined using the log-rank test.ResultsIn 166 patients with adnexal tumors, 41 benign tumors, 113 metastatic tumors to the adnexa, and 12 primary adnexal cancers were diagnosed. Age older than 46 years, a tumor type associated with a high risk for malignant adnexal tumors, and bilateral tumors significantly increased the risk of malignant adnexal tumors. The overall survival of the patients with stomach cancer was significantly worse than the patients with colorectal or breast cancers.ConclusionOne hundred twenty-five of the 166 patients with nongynecologic malignancies who had adnexal tumors managed surgically were shown to have malignant tumors, and most of the tumors were metastatic from primary sites. The risk of malignant adnexal tumors was associated with age, nongynecologic malignancy, and bilaterality.

Sacrococcygeal teratomas are the most common solid tumor in newborn infants. The diagnosis is not difficult in many cases; however, there should be additional information on imaging studies in order to manage those infants properly. Details include histology, morphologic classification, complications such as rupture, bleeding, and mass effects on the adjacent structures. Although imaging features cannot accurately predict the histologic subtypes of the tumors, thorough evaluation of the imaging features can help distinguish malignant tumors from benign tumors. In this article, pathogenesis, histological characteristics, clinical considerations, and morphologic characteristics will be discussed.

Aim. To investigate the clinical and endocrinological characteristics of patients with adrenal incidentaloma (AI). Materials and Methods. This retrospective study enrolled 1941 AI patients hospitalized at the Department of Endocrinology, Chinese PLA General Hospital, Beijing, China, between January 1997 and December 2016. The patient gender, age at visits, imaging features, functional status, and histological results were analyzed. Results. Of the 1941 patients, 984 (50.70%) were men. The median age was 52 years (interquartile range: 44–69 years). 140 cases had bilateral AI. Endocrine evaluation showed that 1411 (72.69%) patients had nonfunctional tumor, 152 (7.83%) had subclinical Cushing syndrome (SCS), and 82 (4.33%) had primary hyperaldosteronism. A total of 925 patients underwent operation for removal of 496 cortical adenomas (53.62%), 15 adrenal cortical carcinomas (1.62%), and 172 pheochromocytomas (18.59%). The bilateral group had a higher proportion of SCS (18.57% versus 7.10%, P<0.001, P=0.006). A mass size of 46 mm was of great value in distinguishing malignant tumors from the benign tumors, with sensitivity of 88.2% and specificity of 95.5%. Conclusions. We reported the baseline demographic and clinical characteristics of patients with AI in a large series from a single center in China.

To investigate the feasibility of thoracoscopic resection, a pilot study was performed in patients with clinically resectable lung tumors. In 40 patients, Video-assisted thoracic surgery (VATS) was performed because of suspicion of malignancy. There were 29 men and 11 women with a median age of 54.8 years (range 18 to 78). Preoperative indications were suspected lung cancer and tumor in 27 patients, assessment of tumor resectability in 7 patients, and probability of metastatic tumors in 6 patients. The final diagnoses in the 27 patients with suspected lung cancer were 12 primary lung cancers, 6 lung metastases, and 9 benign lesions. The success rates for VATS (no conversion to thoracotomy) were 1 of 12 (8.3%) for resectable stage I lung cancer, 8 of 12 (66.7%) for metastatic tumors, and 9 of 9 (100%) for benign tumors. With VATS, 6 of 7 patients (85.7%), possible stage III non-small cell lung cancer, an explorative thoracotomy with was avoided, significantly reducing morbidity. The reasons for conversion to thoracotomy were 1) oncological (N2 lymph node dissection and prevention of tumor spillage) and 2) technical (inability to locate the nodule, central localization, no anatomical fissure, or poor lung function requiring full lung ventilation). The ultimate diagnoses were 19 lung cancers, 12 metastatic lung tumors, and 9 benign lung tumors. Our data show the limitations of VATS for malignant tumors in general use. These findings, together with the fact that experience in performing thoracoscopic procedures demonstrates a learning curve, may limit the use of thoracoscopic resection as a routine surgical procedure, especially when strict oncological rules are respected.

Basically malignant tumors in the retroperitoneal region arise from a heterogeneous group of tissues: mesodermal, neurogenic, germ cell, and lymphoid. Although rare, benign tumors and cystic masses can be also encountered in retroperitoneal space. Developments in computed tomography (CT) and magnetic resonance imaging (MRI) have contributed to both diagnosis and staging of the retroperitoneal tumors. High spatial resolution and superiority in calcification make CT indispensable; on the other hand, MRI has a better soft-tissue contrast resolution which is essential for the assessment of vascular invasion and tissue characterization. The aim of this article is to review the CT and MRI features of retroperitoneal tumors and their subsequent management.

AIM: To describe the clinicopathologic features and classification of pediatric and adolescent ocular tumors and tumor-like lesions METHODS: A total of 719 cases of pathologically confirmed ocular tumors and tumor-like lesions in a pediatric population from two academic institutions over an 18-year period were retrospectively analyzed. The main outcome measures were the clinical and pathological features of the cases. RESULTS: Benign tumors accounted for 92.1% of all cases while malignant tumors accounted for 7.9%. The most common ocular benign tumors were (epi-)dermoid cysts (19.8%), nevi (15.2%), corneal dermoid tumors (9.8%), and calcified epitheliomas (8.8%). The most common ocular malignant tumors were retinoblastoma (80.8%), and rhabdomyosarcoma (3.9%). Eyelid and ocular surface tumors comprised 73.3% of benign tumors while intraocular and orbital cavity comprised 94.2% of malignant tumors. For tumor site, the upper eyelid was up to 1.79 times more than lower eyelid (P<0.05). Age at surgery and sex also had an association with different lesions (P=0.006, P=0.035, respectively). CONCLUSION: Most ocular tumors and tumor-like lesions in children and adolescents are benign. Pediatric ocular tumors are distinct from those in adults in terms of histological origin. (Epi-)dermoid cysts are the most common benign tumors while retinoblastomas the most common malignant tumors.

Background: The patellofemoral joint parameters and imaging presentations of patellar tumors and tumor-like lesions are not clear. Objectives: The aim of this case-control study was to investigate patellofemoral joint parameters, clinical data and findings in patients with patellar tumors and tumor-like lesions. Patients and Methods: Twenty-nine patients with patellar diseases were enrolled. Morphological measurement was performed and analyzed in fourteen patients with patellar tumors (tumor group) and another fifteen patients without patellar diseases (control) who had complete computed tomography data as the control group. Results: Among 29 patients, there were twenty benign lesions (69.0%) and nine malignant tumors (31.0%). Benign lesions included chondroblastoma in nine patients (31.0%), giant cell tumor of bone in four (13.8%), chondroma in one (3.4%), hemangioma in one (3.4%), parosteal lipoma in one (3.4%), bone cyst in two (6.8%), aneurysmal bone cyst in one (3.4%), and fibrous dysplasia in one (3.4%). Malignant tumors were bone metastasis in four patients (13.8%), osteosarcoma in three (10.3%) including common osteosarcoma in two and well-differentiated osteosarcoma in the remaining one, chondrosarcoma in one (3.4%) and hemangiopericytoma in one (3.4%) patient. Chondroblastomas, giant cell tumors and fibrous dysplasia showed findings of expansile bone destruction lesions in imaging. Malignant tumors had bone destruction with ill-defined margins. The femoral trochlear angle was significantly greater in the tumor than the control group (P < 0.001, 159.19º ± 9.42º vs. 135.00º ± 5.50º), whereas the lateral pulley inclination (P = 0.01, 14.69º ± 8.91º vs. 20.73º ± 3.51º) and trochlear depth (P < 0.001, 3.10 ± 1.79 vs. 6.67 ± 1.26 mm) were significantly smaller in the tumor than the control group. Conclusion: The patellar tumors are mainly benign and rarely malignant. Comprehensive understanding of the distribution, incidence and imaging features of patellar tumors and patellofemoral morphological parameters can improve the diagnosis accuracy.
