Intermetatarsal bursa primary synovial chondromatosis: case report and review of the literature.

Primary synovial chondromatosis is a benign neoplastic process, occurring mostly in large joints, more rarely in tendon sheaths, and extremely uncommonly in bursae. We describe a patient with primary synovial chondromatosis arising in the fourth intermetatarsal bursa. Knowledge of the bursal anatomy of the forefoot, and of characteristic imaging findings and the pathogenesis of synovial chondromatosis, is essential in including this uncommon entity in the differential when occurring in unusual locations.

Absent cavum septum pellucidum: a review with emphasis on associated commissural abnormalities.

The cavum septum pellucidum (CSP) is an important fetal midline forebrain landmark, and its absence often signifies additional underlying malformations. Frequently detected by prenatal sonography, absence of the CSP requires further imaging with pre- or postnatal MRI to characterize the accompanying abnormalities. This article reviews the developmental anatomy of the CSP and the pivotal role of commissurization in normal development.

Endovascular interventions for traumatic portal venous hemorrhage complicated by portal hypertension.

Life-threatening hemorrhage rarely occurs from the portal vein following blunt hepatic trauma. Traditionally, severe portal bleeding in this setting has been controlled by surgical techniques such as packing, ligation, and venorrhaphy. The presence of portal hypertension could potentially increase the amount of hemorrhage in the setting of blunt portal vein trauma making it more difficult to control.

Embolization of a large high-flow renal arteriovenous fistula using 035″ and 018″ detachable coils.

Transcatheter embolization of renal arteriovenous fistula (AVF) is a minimally invasive procedure that, in some occasions, can replace surgery and potentially save the kidney. The embolization techniques for the renal AVFs have evolved considerably with the availability of newer hardwares. Still, the risk of inadvertent migration of the embolization materials to the pulmonary circulation is a concern.
