Purpose. To demonstrate capabilities and features in spleen pathology diagnostics based on clinical experience of Botkin City Hospital.Materials and methods. The analysis of 89 patients with spleen abnormalities was performed in the term from 01/2014 till 08/2020. All the patients underwent computed tomography (CT) and/or magnetic resonance imaging (MRI) with contrast enhancing. All cases verified surgically and/or clinically.Results. There were 37 cases of trauma (42%). Accuracy and precision of the method was 100%. In detection of active bleeding the highest diagnostic accuracy (100%) was shown with extravasation symptom – 7 cases. In non-traumatic group (n = 52, 58%) two biggest sub-groups were abscesses (n = 19, 36% in this group) and infarctions (n = 15, 29%). There were 8 cases of cysts (15%), 3 of them – hydatid, 5 cases of spleen hemangiomas. (9.6%), 3 cases of spleen metastases (6%). There was 1 case of angiosarcoma (2%) and 1 case cystic lymphangioma (2%).Conclusion. The most frequent condition in spleen pathology, diagnosed in radiology department is trauma. In non-traumatic cases two biggest groups are abscesses and infarctions. CT features of spleen infarction are pyramidal wedge of hypoperfused splenic tissue with the apex pointing towards the hilum, and the base on the splenic capsule. In all cases in our study cysts were incidental findings. Spleen metastases are rare due to organ hemodynamics. The most rare lesions of the spleen are primal tumors.

Objective: The objective of this study was to outline a novel unique concept of secondary impingement of the muscles, myotendons, and tendons of the rotator cuff from hypertrophy as a result of strength training exercises. Methods: In this retrospective observational study, 58 patients were referred for an magnetic resonance imaging (MRI) by the orthopedic surgeon to the radiology department over a period of 1½ years. All patients gave a history of strength training exercises and presented with clinical features of rotator cuff impingement. Results: We identified features of hypertrophy of rotator cuff muscles, myotendons, and tendons in 12 of these 58 patients. This was the only abnormality on MRI. The hypertrophy of rotator cuff muscles and tendon bulk completely filling the subacromial space to the point of overfilling and resulting in secondary compressive features. Conclusion: Rotator cuff impingement is a common phenomenon that can occur with various inlet and outlet pathological conditions. However, rotator cuff impingement may also result from muscle and tendon hypertrophy from strength training regimens. Hypertrophy of the rotator cuff can result in overfilling of the subacromial space, leading to secondary impingement, which we have termed as “pseudo-impingement.”

This chapter, found in the back pain section of the book, provides a succinct synopsis of a key study examining incidental findings on magnetic resonance imaging (MRI) of the lumbar spine in patients without back pain. This summary outlines the study methodology and design, major results, limitations and criticisms, related studies and additional information, and clinical implications. The study showed that many people without back pain have disk bulges or protrusions on imaging of the lumbar spine, but that these findings are frequently coincidental and should not necessarily lead to further tests or interventions. In addition to outlining the most salient features of the study, a clinical vignette and imaging example are included in order to provide relevant clinical context.

Magnetic Resonance Imaging Mri

Magnetic resonance imaging (MRI) is a noninvasive imaging tool that utilizes a strong magnetic field and radio frequency waves to visualize in great detail organs, soft tissue, and bone. Unlike conventional x-rays (including computed tomography [CT]), there is no exposure to ionizing radiation and at most field strengths (generally below 7 Tesla) the procedure is considered safe for nearly every age group. Because it is non-invasive (i.e., does not break the skin or harm the body) and possesses excellent spatial resolution (down to millimeters), the use of MRI as a research tool has increased exponentially over the past decade. Uses have ranged from add-ons to a clinical study (e.g., after scanning a child who has fallen from a bicycle, the radiologist might do an extra sequence to explore ways of obtaining higher resolution images) to studies of brain development in typically developing children. In addition, a major effort has been made in recent years to use MRI to study brain function (so-called “functional MRI” [fMRI]). Because the clinical utility of fMRI has not yet been realized, fMRI is still considered highly exploratory, and we cannot yet identify incidental findings of a functional (as opposed to structural) nature.

Cystic lymphangioma is an uncommon benign tumor that occurs primarily in children in the cervical region. We report the first case of a pleural-based cystic lymphangioma in an infant. The patient was admitted for RUL pneumonia. Because of the persistence of the radiographic findings despite clinical improvement, a computed tomography (CT) and a magnetic resonance imaging (MRI) scan were performed. They showed a multiloculated cystic lesion in the superior posterior right hemithorax. A surgical procedure was performed with complete resection of the tumor. Histopathological examination showed a pleural-based intrathoracic multicystic lymphangioma. One year after the surgery, the patient feels well without any sign of recurrence.

Abstract The objective of this study was to determine the diagnostic accuracy of B-scan in predicting retinoblastoma (Rb) taking Magnetic Resonance Imaging (MRI) as a gold standard. A cross-sectional validation study was conducted in the Radiology Department of Fauji Foundation Hospital from  May 20 to Nov 20, 2017. Children fulfilling the inclusion criteria were selected after informed consent and detailed history was taken for investigation of Rb. B-scan of both eyes was done using 7.5-10 MHz probe, followed by MRI of both eyes in the same patients using 1.5 Tesla MRI machine with the help of qualified MRI technicians. Data analysis was done by SPSS version 16.0. The diagnostic accuracy, sensitivity, specificity, PPV and NPV of B-scan in prediction of Rb as compared to MRI was 90.45%, 82.28%, 90.54% and 90.28% respectively. The study concluded that diagnostic accuracy of B-scan as compared to MRI is substantial in Retinoblastoma. Continuous...

AbstractObjective:To determine the frequency of incidental findings found on magnetic resonance imaging scans of the internal auditory meatus performed to investigate audiovestibular symptoms, and to determine how to best manage these when found.Method:A retrospective review was conducted of internal auditory meatus magnetic resonance imaging scans during a three-month period in the radiology department at a UK district general hospital.Results:A total of 109 scans were reviewed. Of these, 92.7 per cent showed no retrocochlear pathology, 0.9 per cent showed vestibular schwannoma, 6.4 per cent revealed vascular loops, and 2.8 per cent showed incidental findings that warranted further action and investigation. Of the scans, 40.4 per cent showed other incidental pathologies such as age-related ischaemic changes, and sinus disease that required no further intervention. Of the magnetic resonance imaging scans reviewed, 49.5 per cent were entirely normal.Conclusion:Almost half of the scans investigating audiovestibular symptoms showed incidental findings. Otolaryngologists should have an understanding of the significance of the most commonly encountered incidental findings, and should counsel patients appropriately and refer them onward when necessary.

The vestibular schwannoma (VS), previously known as acoustic neuroma, is a benign tumor that originated from the edge of the Schwann’s sheath of the eighth cranial nerve. It is considered the most frequently diagnosed intracranial benign tumor, of low lethality rate, and unknown etiology. Because of improvement of diagnostic tests and widespread use of magnetic resonance imaging (MRI) and computed tomography (CT) scan, the prevalence of diagnosed acoustic neuroma has increased. Current studies suggest rate may be higher considering undiagnosed asymptomatic patients and incidental findings on radiological examinations in older adults. The etiology of VS is still unclear, and investigations for risk factors are limited. Symptoms at presentation can vary from asymptomatic to complete hearing loss. Medical management can include a “wait and watch” approach, surgical resection, or radiation therapy. The decision depends on the patient’s age at identification, tumor size, severity of symptoms, patient’s preference, and other medical conditions.

Objective: To explore incidental findings on brain magnetic resonance imaging (MRI) studies of pediatric patients referred due to endocrine disorders. Methods: A retrospective, observational study conducted in a tertiary referral center. The neuroimaging database of 17,445 brain MRI studies of 11,011 pediatric patients were searched for cases with endocrine referrals and without medical history of malignancy, genetic syndromes, and/or neurologic comorbidities. This database was linked to the pediatric neurosurgical database. Clinical data were retrieved from medical files. Results: In total, 524 patients (50.2% males, mean age 8.5 ± 3.5 years) were referred to brain MRI due to growth disturbances (n = 313), pubertal disorders (n = 183), prolactin hypersecretion (n = 18), central diabetes insipidus (n = 8), and obesity (n = 1). Incidental findings were found in 128 (24.4%) cases. Chiari type 1 malformation was more prevalent in patients with growth disturbances ( P<.001). Small pituitary cysts were observed in 20 (3.8%) patients, and pineal cysts in 25 (4.8%) patients, mostly girls (68%, P<.001). White matter lesions were diagnosed in 30 (5.7%) patients, none with clinical evidence of neurologic disease. Brain asymmetry without clinical significance and developmental venous anomalies were observed in 14 (2.7%) and 8 (1.5%) patients, respectively. Twelve patients were diagnosed with intracranial tumors, and 5 required surgical intervention for a histopathologic diagnosis of juvenile pilocytic astrocytoma (n = 3), choroid plexus papilloma (n = 1), or inconclusive (n = 1). The rest were managed conservatively. Conclusion: Incidental findings on brain MRIs of pediatric patients referred by endocrinologists are common and raise dilemmas. The spectrum ranges from structural disruptions to tumors. Decision-making is individualized and patient-centered.
