ABSTRACT
Portal vein aneurysms are uncommon incidental imaging findings. They usually do not require any treatment unless symptomatic. Contrast enhanced CT is the imaging modality of choice for depicting its morphology and extension.

Benign or malignant hepatic lesions may rarely mimic inflammatory lesions on imaging. We describe a case of young adult male presenting with pain abdomen and fever of short duration. Imaging revealed large complex multiseptated lesion in the right lobe of liver. Complicated hydatid cyst was kept as first differential diagnosis depending on clinic-radiologic findings. However, due to few atypical imaging features, FNAC of the lesion was performed which confirmed the lesion as UESL.

Intense enhancement of the quadrate lobe in the arterial phase may be seen on computed tomography in patients of superior vena cava syndrome. We present this imaging finding in a case of lymphoma causing superior vena cava syndrome and discuss the physiological cause and importance of this sign.

Spontaneous rupture of hepatic metastasis causing hemoperitoneum is a rare entity. Ruptured hepatic metastasis has typical imaging findings on biphasic CT which may help in clinching the diagnosis. We present a case of rupture hepatic metastasis from choriocarcinoma in a young-female patient who was managed by transcatheter hepatic artery embolization. A brief review of the imaging features and therapeutic options for the ruptured hepatic metastases is discussed along with the case.

BACKGROUND & AIM: Imaging modalities have a role in the diagnosis of patients with nonalcoholic fatty liver disease. Aim of the present study was to evaluate the role of chemical shift magnetic resonance imaging in assessing hepatic steatosis and fibrosis in patients with nonalcoholic fatty liver disease. METHODS: Chemical shift magnetic resonance imaging was done in 10 biopsy proven patients (7 females, mean age 41 +/- 9.2 years) with nonalcoholic fatty liver disease. Objective measurements of signal intensity (SI) were done and a ratio was calculated (SI out-of- phase liver/ SI out-of- phase kidney)/ (SI in- phase liver/ SI in-phase kidney). A lower ratio indicated a higher signal drop and hence higher fat content. The ratio was correlated with hepatic steatosis on histology (< 33% and > 33%). Patients were classified as having histological NASH or no NASH and MRI was assessed in diagnosing hepatic fibrosis as seen on liver histology. RESULTS: Six patients had > 33% hepatic steatosis on histology. Five patients (50%) had evidence of histological NASH. MRI was not helpful in differentiating patients with and without histological NASH. One patient amongst NASH patients did not have fibrosis, one had stage 1, 2 had stage 2 and one had stage 4 fibrosis. SI ratio ranged between 0.35-0.69 in 6 patients with steatosis > 33% and was in the range of 0.69-1.20 in four patients with steatosis < 33% on histology. Fibrotic changes seen in 4 patients on biopsy were not detected on MRI. CONCLUSION: Chemical shift MRI provides objective data on fat infiltration in patients with NAFLD without giving information about hepatic fibrosis.
