Cases of CSFoma
AP and lateral radiographs of the abdomen show the VP shunt to be coiled upon itself and there is a suggestion of a retrogastric mass on the lateral view. Transverse US of the left upper quadrant of the abdomen shows a large cystic structure with the VP shunt tip within it.Axial CT with intravenous and oral contrast of the abdomen shows an extremely large mass filling the abdomen with the tip of the VP shunt within it which is causing hydronephrosis and displacement of the bowel.
