Computed tomography guided radiofrequency ablation of multifocal osteoid osteoma.

Osteoid osteoma is a benign osteoblastic tumor characterized mostly by presence of one nidus, butvery infrequentlyniduses can be multiple. Radiofrequency ablation is a well-established treatment method for this disease. We report a case of a 19-year-old male patient with bifocal osteoid osteoma which was partially missed on the initial magnetic resonance imaging and treated successfully with two sessions of radiofrequency ablation.

HEPATIC ARTERIAL ANATOMY VARIATIONS IN PATIENTS WITH HEPATOCELLULAR CARCINOMA EVALUATED BY COMPUTED TOMOGRAPHY ANGIOGRAPHY.

Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and one of the major reasons for performing percutaneous endovascular procedures or liver surgery. Hepatic arterial anatomy is of major importance in performing these procedures on the liver. The aim of our study was to estimate the prevalence of various hepatic arterial variants in HCC patients.

Multidetector computed tomography angiography in the management of transarterial embolization of primary and secondary liver malignancy.

Background: Endovascular management is the mainstay of therapy for most patients with primary and secondary liver tumors. Radiologist should understand the anatomy of the hepatic vasculature and tumor feeding vessels to ensure successful conduction of the embolization procedure. The aim of this study was to evaluate the accuracy of multidetector computed tomographic angiography (MDCTA) for the evaluation of hepatic arterial anatomy and tumor feeding vessels prior to embolization procedure.
