Diagnosis and management of radiation cholecystitis as a complication of Y90 radioembolization for hepatocellular carcinoma.

Radiation induced cholecystitis is a known but rare complication of Yttrium90 (Y90) radioembolization of hepatic tumors due to nontarget embolization. Many documented cases of radiation induced cholecystitis have been treated with cholecystectomy, which is significant given the typical patient population undergoing radioembolization tends to be of higher surgical risk. Here, we present a case of a 68 year old male who developed radiation induced cholecystitis status post hepatic radioembolization that resolved with conservative management alone.

Spontaneous Contralateral Adrenal Hemorrhage during Periduodenal Abscess Drain Placement.

A spontaneous adrenal hemorrhage is a rare complication occurring in the setting of interventional radiology procedures. Here, we present the case of a 73-year-old male who underwent CT-guided drainage of a periduodenal collection. During the procedure, he developed sudden onset left back pain and hypertension, which revealed a left adrenal gland hemorrhage on CT imaging.

Interventional Radiology and Pregnancy: From Conception through Delivery and Beyond.

Interventional radiology (IR) plays a unique and often invaluable role in the care of pregnant patients. Special considerations regarding radiation exposure and medication choice must be taken into account when evaluating a pregnant patient for an interventional procedure. In addition, the physiologic changes that occur during pregnancy can pose special challenges for an interventionalist when treating this patient population and should be appropriately recognized.

Complex Arterial Pathology of Angiomyolipomas of Tuberous Sclerosis.

Based on observations at angiography, it was hypothesized that angiomyolipomas (AMLs) associated with tuberous sclerosis complex (TSC) have a more robust parasitic blood supply and require more complex embolization involving lower order vessels compared with the non-TSC patients' AMLs. This was a retrospective review of 71 patients who underwent angiography and embolization for renal AML at multiple centers within a single health system. All of the patients with TSC (11/11) were found to have "complex" tumor vascular supply.
