ABSTRACT
Hibemoma is a rare benign soft tissue tumor derived from brown fat.The tumor is also known as "fetal lipoma, lipoma of embryogenic fat and lipoma of immature adipose tissue. Hibemomas are slow-growing, painless soft tissue tumors which do not recur after surgical resection. Preferred locations are brown fat containing sites as thigh, interscapular region, shoulder, axilla, and mediastinum.The tumor occurs most commonly in adults, with a mean age of 38 years (age range, 2-75 years). We present a rare case of hibernoma with radiological and pathological findings.

INTRODUCTION: Our purpose was to determine whether diffusion-weighted MR imaging (DWI) could be used in differentiation of benign and malign breast lesions. MATERIALS AND METHODS: 41 women patients were included in the study. 45 lesions were diagnosed by biopsy; 25 (55.5%) of these lesions were malignant and 20 (44.5%) were benign. The apparent diffusion coefficient (ADC) values of these lesions were prospectively compared with their histopathological results. RESULTS: Differentiation of the malignant and benign masses revealed that the threshold value of the ADC was 1.0 x 10(-3) mm(2)/s, its sensitivity was demonstrated as 95%, specificity as 100%, positive predictive as 100%, negative predictive as 94% and accuracy rate as 97%. CONCLUSIONS: DWI improves diagnostic accuracy of the conventional breast MRI. ADC measurements may be useful for differentiation of the malign and benign masses.

We report our experience treating four patients with acutely bleeding angiomyolipoma (AML) of sizes between 4 and 12 cm who were managed with endovascular embolisation with a mean follow-up of 10 months. In our case series, we demonstrate that endovascular embolisation in the acute setting for bleeding AMLs is a viable treatment option. AML should be in the differential diagnosis of acutely bleeding renal masses, even when there is no fat assessed by computed tomography (CT) imaging in the renal mass.
