Fibrous Tumor

A calcifying fibrous tumor (CFT) is a benign tumor of unknown etiology. A calcifying fibrous tumor is rare in the intestinal tract. A calcifying fibrous tumor is characterized by hyalinized collagenous fibrous tissue, psammomatous or dystrophic calcification, and focal lymphoplasmacytic infiltrates on histology. Magnetic resonance imaging is the standard method for evaluating the lesions of the rectum, and CFTs should be considered in differentiating the rectal wall tumors. Herein, we report a case of a 68-year-old man with a rectal wall CFT.

Abstract Background The aim of this study was to: (i) describe the abnormalities seen on brain imaging in a group of children with en coup de sabre (EDCS) with/without Parry-Romberg syndrome (PRS); and (ii) identify clinical predictors of brain imaging abnormalities. Methods This was a single centre (Great Ormond Street Hospital, London) retrospective case series of patients with ECDS/PRS seen from 2000 to 2018. We identified patients with cutaneous manifestations consistent with the clinical descriptions of ECDS/PRS. Presenting clinical, laboratory, and radiological brain findings are described. Results are expressed as medians and ranges or frequencies and percentages. Fisher’s exact test was used to identify clinical associations with magnetic resonance imaging (MRI) abnormalities. Results Fourteen patients were studied: 6 males and 8 females; median age 14 years (range 3–20). We observed neuroimaging abnormalities in 2/6 ECDS and 5/8 ECDS/PRS patients. White matter signal abnormality, dystrophic calcification, leptomeningeal enhancement, and sulcal crowding were the typical findings on brain imaging. A total of 50% of patients had no MRI abnormality despite some of these patients having neurological symptoms. The presence of seizures was significantly associated with ipsilateral enhanced white matter signalling on MRI (p < 0.05). Conclusions In summary, we observed several distinct radiographic patterns associated with ECDS/PRS. Seizure disorder was strongly associated with the presence of ipsilateral enhanced white matter signalling. Improved neuroimaging techniques that combine morphological with functional imaging may improve the detection rate of brain involvement in children with ECDS/PRS in the future.

Sarcoidosis is a granulomatous multisystem disease of unknown etiology. Typically, the disease affects the lungs, causing enlargement of the mediastinal lymph nodes, but other organs can be affected. Neurosarcoidosis is reported in 5–10% of the patients. This case represents a 39-year-old male patient diagnosed with lung sarcoidosis. Due to neurological symptoms, a contrast-enhanced cerebral magnetic resonance imaging was performed. Neurosarcoidosis was presented with meningeal enhancement adjacent to a cyst located within the cavum septum pellucidum. The cyst dissolved spontaneously within six months. The finding of a cyst located within the septum pellucidum is rare.

Apical Hypertrophic Cardiomyopathy

Introduction. About 0.2 % of the adult population all over the world suffers from hypertrophic cardiomyopathy. Early and timely diagnosis of the apical form of hypertrophic cardiomyopathy remains an urgent medical problem, since the disease has a wide variability of clinical manifestations and often occurs asymptomatic or with symptoms of other heart diseases. Magnetic resonance imaging is an informative method of radiation diagnosis of hypertrophic cardiomyopathy. The aim is improving of radiology diagnostics in applying to the apical form of hypertrophic cardiomyopathy. Materials and methods. 98 patients with apical hypertrophic cardiomyopathy aged 19 to 76 years were еxamined. There were 48 men and 50 women. All subjects were examined by a cardiologist, all patients underwent electrocardiography and echocardiography, 45 patients underwent magnetic resonance imaging (MRI) of the heart. Results. In our study 13 patients had MRI determined the isolated form of apical form of hypertrophic cardiomyopathy, 32 had combined one. 42.2% of the patients with symmetrical hypertrophy of all apical segments had sawtoothed configuration of the LV revealed by MRI. The symptom of left ventricular cavity obliteration was determined in 19 patients. The symptom of LV cavity sequestration was determined in 5 subjects. 5 patients had an aneurysm on the top of the left ventricle, 1 – on the top of the right ventricle. Signs of left ventricular outflow tract obstruction were visualized in 2 patients, intraventricular obstruction at the level of the middle segments of the left ventricle was determined in 5 cases. Akinesis and hypokinesis were detected in areas of fibrous changes (n=21) or in areas of cardiosclerosis (n=2). In 17.8 % of subjects identified non-compacted myocardium, in 3 cases it was combined with apical form of hypertrophic cardiomyopathy. With contrast enhancement in 29 patients, foci (n=22) or zones (n=7) of pathological accumulation of contrast agent were determined, which indicated the replacement of myocardium with fibrous tissue.

Background Preoperative prediction of postoperative tumor progression of intracranial grade II–III hemangiopericytoma is the basis for clinical treatment decisions. Purpose To use preoperative magnetic resonance imaging (MRI) semantic features for predicting postoperative tumor progression in patients with intracranial grade II–III solitary fibrous tumor/hemangiopericytoma (SFT/HPC). Material and Methods We retrospectively analyzed the preoperative MRI data of 42 patients with intracranial grade II–III SFT/HPC, as confirmed by surgical resection and pathology in our hospital from October 2010 to October 2017, who were followed up for evaluation of recurrence, metastasis, or death. We applied strict inclusion and exclusion criteria and finally included 37 patients. The follow-up time was in the range of 8–120 months (mean = 57.1 months). Results Single-factor survival analysis revealed that tumor grade (log-rank, P = 0.024), broad-based tumor attachment to the dura mater (log-rank, P = 0.009), a blurred tumor-brain interface (log-rank, P = 0.008), skull invasion (log-rank, P = 0.002), and the absence of postoperative radiotherapy (log-rank, P = 0.006) predicted postoperative intracranial SFT/HPC progression. Multivariate survival analysis revealed that tumor grade ( P = 0.009; hazard ratio [HR] = 11.42; 95% confidence interval [CI] = 1.832–71.150), skull invasion ( P = 0.014; HR = 5.72; 95% CI = 1.421–22.984), and the absence of postoperative radiotherapy ( P = 0.001; HR = 0.05; 95% CI = 0.008–0.315) were independent predictors of postoperative intracranial SFT/HPC progression. Conclusion Broad-based tumor attachment to the dura mater, skull invasion, and blurring of the tumor–brain interface can predict postoperative intracranial SFT/HPC progression.

Both benign and malignant conditions related to regional or systemic disorders could be included in the differential diagnosis of bilateral breast edema. Some of them are often unilateral, including stromal infiltration and lymphatic obstruction presented in “peau d’ orange”, which is the usual presentation of breast cancer. However, the term “idiopathic” could be included in the spectrum of diagnoses. Here, we present a woman of 78 years old who came into our breast unit with a bilateral, painless edema of the breasts (appeared one month ago). Clinical examination revealed that both breasts were swollen with widespread erythema and the appearance of an orange peel/“peau d’ orange”. On palpation, the breasts were not sensitive, and no tumor was palpable. However, clinically palpable lymph nodes were found in both axillas. Her temperature was normal. The breast edema could not be explained from her medical history nor the medications taken. Breast ultrasound, Mammography and Magnetic Resonance Imaging were non-conclusive (BI-RADS 0) and bilateral core biopsy was negative for cancer. Anti-inflammatory plus antibiotic therapy was prescribed for 10 days and at the end of treatment, regional redness and edema were disappeared and reduced, respectively. Total recovery was found one month after the initial findings. It can be concluded that bilateral breast edema is correlated to regional or systemic conditions or it is presented as an “idiopathic” disorder of unknown etiology.

ObjectiveThe differential diagnosis between uterine sarcoma and benign leiomyoma is difficult when made only by magnetic resonance imaging (MRI); it usually requires an additional preoperative diagnostic procedure. We report our results using ultrasound-guided needle biopsy for these types of uterine tumors.MethodsUltrasound-guided needle biopsy was performed on 63 patients with uterine smooth muscle tumors suspected of malignancy by MRI. We compared the results of presurgical biopsy against the postsurgical pathology of the tumor.ResultsAmong 63 patients with a high signal intensity of the uterine tumor on T2-weighted MRI (1 case was undetermined), 12 cases (19.3%) were diagnosed by the needle biopsy as malignant, and 51 cases (80.6%) were benign. Among the 12 diagnosed as malignant tumors, 11 had surgery performed, and one was treated with chemotherapy. Among the 51 patients diagnosed with a benign tumor, 27 had surgery performed, and 24 were put on a wait-and-see clinical follow-up schedule. One of the 27 surgical patients with a benign tumor had a postsurgical diagnosis of a low-grade endometrial stromal sarcoma. In the 38 cases where surgery was performed, we found the sensitivity, specificity, and the positive and negative predictive values of the needle biopsy were 91.7%, 100%, 100%, and 96.2%, respectively.ConclusionsUltrasound-guided needle biopsy may be a reliable preoperative diagnostic procedure for uterine tumors with suspected malignancy.

Pain Patients

Two cases of fibrous myopathy associated with repeated, long-term intramuscular injections for treatment of chronic temporomandibular joint pain and chronic headache, respectively, are described. Both patients developed severe, function-limiting contractures in upper and lower extremity muscles used as injection sites. In one of the cases, the contractures were painful. Electrophysiological testing, magnetic resonance imaging and muscle biopsy results were all consistent with myopathy and replacement of skeletal muscle with noncontractile fibrous tissue. These cases are presented to increase awareness of fibrous myopathy and to promote surveillance for this serious potential complication of long-term intramuscular injections in chronic headache and other pain patients.

Mediastinal Involvement

Six patients with mediastinal involvement of Hodgkin's disease were examined with magnetic resonance imaging (MRI) at 0.35 T before and/or at various stages of therapy, with the sequences TR/TE: 500/35, 500/70, 1600/35 and 1600/70. Before therapy the image intensity of tumour involved lymph nodes deviated considerably from fat and muscle, but no clear difference was discerned between histopathologic subtypes or tumour localizations. After efficient therapy, the tumour image intensities and relaxation rates approached those of muscle and fibrous tissue, but remained at pre-therapy values when the patient was not in full remission. A similar pattern was found in a ‘normal-tissue’—‘tumour’ plot, based on vector analysis of the original sets of 4 images. It is concluded that persistent tumour involvement in the mediastinum may be distinguished from fibrosis and that MRI may thus be of value in the follow-up of patients with Hodgkin's disease.

A solitary fibrous tumor seldom originates from the meninges, and the accuracy of imaging modalities in the diagnosis of meningeal SFT metastasisis is perlexing. Contrast enhanced imaging modalities, such as contrast enhanced ultrasound and contrast enhanced magnetic resonance imaging are valuable in the differential diagnosis of hepatic neoplasms. This case report demonstrated the contrast enhanced ultrasound and enhanced magnetic resonance imaging features of one case of liver metastasis from a menigeal solitary fibrous tumor.
