Morel-Lavallée lesions are post-traumatic, closed degloving injuries occurring deep to subcutaneous plane due to disruption of capillaries resulting in an effusion containing hemolymph and necrotic fat. Magnetic resonance imaging (MRI) is the modality of choice in the evaluation of Morel-Lavallée lesion. Early diagnosis and management is essential as any delay in diagnosis or missed lesion will lead to the effusion becoming infected or leading to extensive skin necrosis.

Tropical chronic pancreatitis (TCP) is a unique juvenile nonalcoholic form of chronic pancreatitis prevalent in tropical developing countries. TCP is characterized by the younger age of onset, rapid progression, higher prevalence of diabetes and pancreatic calculi, and greater propensity to develop pancreatic malignancy. Identifying the distinct imaging features is critical for the diagnosis of TCP. Awareness of this condition will not only enable the radiologist to recognize it early but also help in better management. In this article, we review the etiopathogenesis, distinct imaging features, and complications of TCP.

BACKGROUNDBreast cancer is the second leading cause of cancer deaths in women today. Important risk factors for female breast cancer include age (increases as women gets older), genetics, early onset of menarche and late age of menopause, family or personal history of breast cancer, obesity, nulliparity, use of HRT and OCPs, consumption of alcohol and a middle to high socioeconomic status. Diffusionweighted imaging is a new MR imaging technique in which contrast within the image is based on microscopic motion of water. It is reported to be highly sensitive for evaluation of breast cancer and a possible means of differentiating benign and malignant tumour. Diffusion is quantified by measuring apparent diffusion coefficient (ADC). This study was performed to determine whether diffusionweighted imaging can be useful for diagnosis of mammographically detected BIRADS 3 & 4 lesions, correlating with histopathological diagnosis and to derive ADC values which may allow distinguishing benign from malignant lesions.
