Angiomatoid fibrous histiocytoma (AFH) is a rare, slow-growing soft tissue tumor with an intermediate biologic potential and uncertain line of differentiation, and minimal metastatic potential. AFH may mimic both the clinical, histological, and radiological findings of several tumors; therefore, it is frequently misdiagnosed.Three cases of AFH were included in this study. A six-year-old male and two females with an age of 12 and 17 years are presented. The primary locations were in the right shoulder (case 1), left medial proximal thigh (case 2), and left lateral knee (case 3). Two cases (cases 2&3) were presented with a painful mass. In the three patients, the masses were firm, mobile, and not attached to the skin.Magnetic resonance imaging (MRI) was done, illustrating unspecific findings to reach a diagnosis. Needle biopsies were performed in all patient, and the diagnosis of AFH was reached. All three patients underwent wide surgical excision of the tumor. Patients were followed up routinely every three to four months with imaging studies to rule out recurrence and metastasis, for a period of 15 months (case 1), 26 months (case 2), and 19 months (case 3), which all resulted negatively.

Charcot knee is a rare condition with few reported cases in the literature. Although the clinical presentation is highly variable, Charcot knee classically presents with painful arthropathy in addition to instability and decreased range of motion. Herein, we describe the case of a 72-year-old man with idiopathic Charcot knee. The diagnosis was established on the basis of history of neuropathic arthropathy of the knee, supported by knee radiographs and the exclusion of all known etiologies of Charcot knee. Because of a highly destructed knee joint, the patient underwent a total knee arthroplasty using the Global Modular Replacement System proximal tibial prosthesis. The surgery was done without any major complications, resulting in symptomatic and functional improvements.

Objectives: Os acromiale (OA) is an uncommon pathology, with a variable prevalence rate among different populations. reporting the frequency of OA utilizing shoulder MRI of patients with shoulder pathology in our institute. Methods: Retrospective chart review to conduct our research. After obtaining our IRB approval we gathered all shoulder and upper arm MRIs from the radiology department and available in PACS. Results: The prevalence of OA was 3.32%, and the mean age of the affected patients was 50.87 years (25–81). In males there were seven OA conditions
