Dendritic fibromyxolipoma with intramuscular involvement: A case mimicking slow flow vascular malformation on imaging.

Dendritic fibromyxolipoma (DFML) is a benign, very rare, and slow-growing soft tissue tumor commonly involving the muscular fascia of the foot, calf, shoulders, back, or head and neck muscles. Many authors consider dendritic fibromyxolipoma a variant of spindle cell lipoma composed of a plexiform vascular pattern, dendritic cytoplasmic processes, and keloidal collagen. Only a few cases have been reported in the shoulder region, and the presented case represents the second case in English literature whose histopathology showed intramuscular involvement. Recognition of such an entity is essential because it is considered a scarce type of benign tumor that can be mistaken for other aggressive neoplasms of myxoid pathology. We present a case of a dendritic fibromyxolipoma around the right shoulder with intramuscular involvement to the superficial fibers of the right trapezius muscle.

Endovascular management of iatrogenic arterial injury post bone marrow biopsy: A report of 3 cases.

Bone marrow biopsy is an important tool for the evaluation of malignant and benign hematologic disorders. Performed blindly, usually with a Jamshidi biopsy needle penetrating the posterior iliac crest bone, the procedure is generally considered safe but rarely complications are observed; vascular complications associated with bleeding are the most serious and potentially life-threatening. We describe 3 cases of arterial injury following a bone marrow biopsy procedure, all treated successfully with minimal invasive endovascular management, and emphasize the need for clinical awareness and recognition of this rare complication in order to facilitate rapid diagnostic and minimal invasive therapeutic interventions, when appropriate, for successful outcomes.

Aggressive gluteal fibromatosis: a rare case associated with spontaneous superior gluteal artery pseudoaneurysm.

Deep fibromatosis is a locally aggressive neoplasm commonly involving the extremities. Several authors have described imaging features and complications associated with deep fibromatosis. We present the case of a 33-year-old man who presented with a right gluteal fibrous mass identified on magnetic resonance imaging (MRI), which was associated with a pseudoaneurysm originating from the right superior gluteal artery on serial follow-up with MRI and computed tomography. No intervention was done, and after conservative management, spontaneous thrombosis of the pseudoaneurysm was developed. Such imaging finding is the first report of a spontaneous development of pseudoaneurysm caused by deep fibromatosis, which could be a life-threatening condition and should be considered when dealing with deep fibromatosis and deciding on the appropriate treatment.

A case of horizontal gaze palsy with progressive scoliosis.

Horizontal gaze palsy with progressive scoliosis is a rare entity with few cases in the literature. Despite the fact the patient will not present with typical symptoms of this syndrome, clinical suspicion should be raised particularly in terms of imaging findings. Imaging findings are characteristic to flag the possibility of this syndrome. Keeping in mind such congenital abnormalities on magnetic resonance imaging particularly for radiologists might help in the management process. Multidisciplinary teams play a crucial role in terms of communication to find the clinical, radiological and genetic studies to reach the diagnosis.

A case of bilateral posterior mediastinal myelolipoma.

A 71-year-old female presented with chronic shortness of breath and underwent routine examination at the emergency department. A plain chest radiograph revealed a large lobulated posterior mediastinal mass that was incidentally found to be unrelated to the main complaint. Further cross-sectional images were obtained to characterize the lesion, which revealed bilateral involvement of a prevertebral mixed attenuation large mass with minimal enhancement postcontrast administration. Images were not conclusive in which the patient underwent ultrasound-guided biopsy and further histopathological examination, which revealed a myelolipoma of the posterior mediastinum, a rare entity to be seen at that location. Here, we present the case of posterior mediastinal myelolipoma.

Unilateral Condylar Hyperplasia With Active Bony Overgrowth: A Case Report.

Condylar hyperplasia (CH) is an overgrowth disorder of the temporomandibular joint bones caused by growth center overactivity of the mandibular condyle. Although the disorder is mostly idiopathic, several etiologies have been proposed. CH presents as progressive facial asymmetry with functional abnormalities. A combination of clinical, histopathological, and radiological findings is crucial to determine the diagnosis. Several diagnostic algorithms have been described in the literature. Management of CH is variable and depends on the growth of the bone. Here, we present the case of a 36-year-old female who presented with progressive facial asymmetry which was diagnosed as unilateral CH with active bony overgrowth.

Atypical Presentation of Acute Appendicitis with Schistosomiasis.

Schistosomiasis is a parasitic infection that is induced by different species of Schistosoma. The infection can manifest with a variety of different pathologies depending on the involved system and causative species. Schistosoma-induced appendicitis is rare in developed countries. We discuss a case of a middle-aged female who was diagnosed with acute appendicitis and underwent appendectomy. Upon histopathological examination of the resected appendix, Schistosoma infestation was identified as the underlying cause.
