This case report demonstrates delayed rupture of a cavernous carotid fistula and aneurysm into the temporal lobe 12 years after treating a direct cavernous carotid artery fistula using detachable silicon balloons. The ultimate treatment was performed using arterial endovascular sacrifice. Successful treatment of cavernous carotid fistulas may ultimately lead to formation of cavernous aneurysms....

A 46-year-old woman presented with massive left temporal lobe intraparenchymal and diffuse subarachnoid hemorrhage on CT. Lack of enhancement excluded intermediate and high-grade primary tumor or metastasis as likely causes. At surgery, a fibrovascular left temporal lobe mass adherent to the dura proved to be a pleomorphic xanthoastrocytoma. The unusual hemorrhagic presentation of this typicall...

Introduction The pleuro-pulmonary changes associated with rheumatoid arthritis are well known. A rare and more specific lesion is the subpleural or intraparenchymal rheumatoid nodule. The pulmonary nodules usually occur in patients with severe disease with subcutaneous nodules and high titres of rheumatoid factor. They may cavitate, and spontaneous pneumothorax may occur (Hindle and Yates, 1965...

Posttransplant lymphoproliferative disorder (PTLD) is a well-described complication of solid organ and bone marrow transplants. The most common presentation is intra-abdominal lymphadenopathy or single or multiple intraparenchymal masses involving the liver, spleen, or kidneys. Here we describe the imaging and pathology findings of an unusual case of PTLD appearing as an intramuscular forearm l...

Angiomatoid fibrous histiocytoma (AFH) is a rare soft-tissue neoplasm that most commonly appears in the limbs, typically affecting children and young adults. The tumor has a propensity for local recurrence and recurrent hemorrhage but rarely for remote metastasis. To date, only 2 reports have documented an intracranial occurrence of the tumor (1 of which was believed to be metastatic disease). ...
