Unusual fissure on the diaphragmatic surface of the spleen – a case report

Introduction Spleen is the largest lymphoid organ of the body. It is situated in the left hypochondrium of the abdomen. It is covered from all the sides by peritoneum and is closely related to the fundus of the stomach, left kidney, left colic flexure and the diaphragm. It has an anterior end and a posterior end; superior, inferior and intermediate borders; diaphragmatic and visceral surfaces. Its superior border shows variable number of splenic notches. Its diaphragmatic surface is totally covered by peritoneum and usually does not show any notches or fissures. The diaphragmatic surface may show grooves formed by the 9th, 10th, and 11th ribs. The shape of the organ depends on the surrounding viscera and it varies from a wedge shape to a tetrahedron. Knowledge of variations of spleen is important for radiologists. We observed an unusual notch on the diaphragmatic surface of the spleen.
