Splenosis is defined as the autotransplantation of splenic tissue resulting from the spillage of cells from the pulp of the spleen after splenic injury or splenectomy. Splenic implants are generally numerous, can be located anywhere in the peritoneal cavity, are supplied by arteries from the surrounding tissue rather than a hilar artery, have no particular shape, and have neither a […]

Gastrointestinal duplication cysts are relatively common congenital anomalies which are composed of fluid-filled sacs lined by a layer of epithelium and smooth muscle from the alimentary tract. They frequently share a common blood supply and muscular wall from the adjacent portion of the intestine. The most common locations are: Distal ileum (34%), esophagus (19%), stomach […]

Normal color doppler ,Renal vasculature     USG shows diffusely hyperechoic kidney with loss of cortico-medullary differentiation Color Doppler shows absent renal vein doppler signal   CT Scan axial section shows hypoattenuating thrombus in the left renal vein CT scan Excretory phase shows enhancement of collaterals around ureter MRA showing low signal thrombus partially obstructing […]

D/D A.In early ischaemic stage :During the early ischemic stage of renal papillary necrosis, corticomedullary or parenchymal phase multi–detector row CT shows a poorly marginated area of decreased enhancement at the tip of the medullary pyramid. .1. Pyelonephritis also may be visible as a circumscribed area of reduced enhancement at CT during the corticomedullary and parenchymal phases, but […]

Infection that […]

On MR images, the hydrosalpinx appears as a fluid-filled tubular structure that arises from the upper lateral margin of the uterine fundus and is separate from the ipsilateral ovary. A dilated fallopian tube folds upon itself to form a sausagelike C- or S-shaped cystic mass as seen below   Sagittal T2-weighted MR image shows an […]
