Objectives: The purpose of the study was to assess the incidence of hepatic vein variations on multidetector CT (MDCT) for abdominal examinations. Methods: A retrospective analysis of 534 MDCT scans was performed in patients sent for various abdominal pathologies between January 2017 and April 2019. After excluding 34 patients, finally total of 500 patients (N = 500) were included in the study. For simplification, we classified the hepatic vein variations as classified by Soyer et al, Fang et al and Cheng et al. Results: Single right hepatic vein was seen in 458 (91.6%) out of 500 patients in our study. Two right hepatic veins were seen in 36 patients out of which 27 had common trunk and nine had independent drainage into the inferior vena cava (IVC). Common trunk of middle hepatic vein (MHV) and left hepatic vein (LHV) was seen in 405 (81%) and independent drainage of MHV and LHV into the IVC was seen in 95 (19%) of patients in our study. Amongst the segmental hepatic vein variations, most common drainage of segment IV vein was into LHV (333,66.6%) followed by MHV (148,29.6%) and IVC (19,3.8%). Conclusion: Hepatic vein variations are commonly seen similar to variations in hepatic artery, portal vein and biliary anatomy. Knowledge of these variations is extremely important for transplant surgeons and intervention radiologists. Advances in knowledge: Awareness of the hepatic vein variations is essential for intervention radiologists and surgeons to reduce iatrogenic complications.

In this article, we emphasize the usefulness and cost-effectiveness of non-contrast MRI as the primary imaging modality in the evaluation of non-febrile pediatric seizure, illustrate the MR spectrum of different structural lesions causing pediatric seizures, and finally describing the main MR imaging features of these disorders. Among 366 cases of pediatric epilepsy studied over a period of fifteen years the commonly detected structural malformations are mesial temporal sclerosis unilateral and bilateral, heterotopias, cortical dysplasia, neurocutaneous syndromes and few neoplasms. MRI showed hippocampal atrophy and increased signal intensity of the hippocampus on T2-weighted images in mesial temporal sclerosis, cortical thickness and sulcation are decreased in microcephaly, enlarged dysplastic cortex in hemimegalencephaly, and focal cortical dysplasia shows ipsilateral focal cortical thickening with radial hyperintense bands. MRI detects smooth brain in classic lissencephaly, the ectopic position of gray matter in heterotopias, and the nodular cortex with cobblestone cortex in congenital muscular dystrophy. MRI can detect polymicrogyria and the related syndromes, as well as schizencephaly types. In conclusion, MR imaging is essential to demonstrate the morphology, distribution, and extent of different disorders causing seizures in children as well as the associated anomalies and related syndromes to guide patient for further surgical treatment and counseling.
