iothalamate-meglumine and Carcinoma--Squamous-Cell

In the CT evaluation of a cystic pelvic mass it is important to identify the urinary bladder and assess its relationship to the mass. Although this is generally an easy task, we have encountered cases where delayed opacification of the bladder created diagnostic difficulties. Following intravenous contrast medium infusion, patients with normal renal function may have unopacified bladders due to (a) delayed transit from kidney to bladder and (b) rapid CT imaging of the bladder before opacification can occur. If one is aware of these problems, diagnostic dilemmas may be reduced by obtaining delayed scans of the pelvis or by obtaining postvoid films. Two cases are presented to illustrate these points.

Ten patients with malignant primary neoplasms of the ear and temporal bone were examined with high-resolution computed tomography (CT) and the results correlated with the operative findings. CT was found to be highly accurate in establishing the presence and extent of tumor and is recommended as the procedure of choice for preoperative treatment planning.
