Interventional Radiology Management of Adult Liver Transplant Complications.

Liver transplant remains the definitive therapy for patients with end-stage liver disease. Outcomes have continued to improve, in part owing to interventions used to treat posttransplant complications involving the hepatic arteries, portal vein, hepatic veins or inferior vena cava (IVC), and biliary system. Significant hepatic artery stenosis can be treated with angioplasty or stent placement to prevent thrombosis and biliary ischemic complications.

Spectrum of imaging findings in hyperplastic cholecystosis and potential mimics.

Adenomyomatosis and cholesterolosis of the gallbladder, collectively termed hyperplastic cholecystosis, are commonly encountered incidental findings on imaging studies performed for a variety of indications including biliary colic or nonspecific abdominal pain. These pathologies are rarely the source of symptoms, generally considered benign and do not require further work-up. However, their imaging characteristics can overlap with more sinister conditions that should not be missed.

Non-Vascular Considerations When Interpreting Extremity Arterial and Venous Examinations.

Peripheral arterial and venous examinations are performed regularly in vascular labs and interpreted by physicians of different specialities. Many vascular examinations have nonvascular pathology that is either inadvertently imaged by the sonographer or imaged with intent as it relates to patient's symptoms. It is prudent for every reader of vascular studies to be acquainted with the sonographic appearance of these non-vascular lesions to enable appropriate and optimal interpretation that has a direct bearing on patient's clinical care.

Identification of Bladder Diverticular Stone on Tc-Methyl Diphosphonate Bone Scintigraphy and SPECT/CT.

We report a bladder diverticular stone with increased Tc-methyl diphosphonate uptake on bone scintigraphy and SPECT/CT. Diverticular stone is a known risk factor for bladder malignancy. The deposition of Tc-methyl diphosphonate on the crystal surface of the diverticular stone is a rare phenomenon but of clinical significance.

Adrenal Tumors Found During Staging and Surveillance for Colorectal Cancer: Benign Incidentalomas or Metastatic Disease?

Objective: To evaluate the incidence of adrenal metastases in patient with colorectal cancer (CRC) and determine the clinical and radiographic features associated metastatic CRC to the adrenal glands.

Materials And Methods: The review of consecutive adults with newly diagnosed CRC found to have adrenal tumors > 1 cm in size on staging or surveillance CT scans with at least two scans to evaluate progression or stability of disease.

Results: Fifty-eight of 856 (6.

Differences in Growth Rate on CT of Adrenal Adenomas and Malignant Adrenal Nodules.

The purpose of this study is to determine the differences in growth rate of adrenal adenomas and malignant adrenal nodules. This was a retrospective review of adults with an adrenal nodule seen at two different abdominal or chest CT examinations or PET/CT examinations. Patients in the adenoma group were included if they had a CT, MRI, or pathologic diagnosis of an adrenal adenoma.
