We report the imaging findings of an abdominal aggressive angiomyxoma, which communicated with the gastrointestinal tract. The literature on this rare tumor is reviewed.
We report heterotopic chondro-ossification occurring in the hand of a young man in the absence of trauma. The differential diagnosis includes: bizarre periosteal osteochondromatous proliferations of the hands and feet, mature lesions of myositis ossificans, osteogenic sarcoma, confluent lesions of extra-articular synovial chondromatosis, and nodular forms of florid periostitis. True heterotopic bone formation is a benign condition, which of itself requires no specific treatment.
A case of systemic lymphangiomatosis in a child is presented and the literature reviewed. Bipedal lymphangiography confirmed the diagnosis by demonstrating bony accumulation of contrast medium, whereas postlymphangiographic computed tomography gave a more accurate assessment of the full extent of bony and visceral involvement.
Observations on computed tomography (CT) of 15 patients with compression of the superior vena cava (SVC) and its tributaries are reported and compared with clinical, radiographic and surgical findings. The site of compression in 14 patients was accurately determined by CT, which could delineate the presence of intraluminal clot and extrinsic compression of venous structures, as well as associated mediastinal masses. Collateral superficial vessels were identified in nine patients with contrast-enhanced scans. Contrast-enhanced mediastinal and chest CT was shown to provide detailed anatomic and physiologic information about the etiology of SVC syndrome.
Conventional and computed tomography findings in a cystic hygroma (lymphangioma) of the middle mediastinum in an adult are reported and compared with previously reported cases. The pertinent literature is reviewed.
