Thirty patients suffering from mass lesion in the parotid gland or cervical region were examined by computed tomography (CT).The photographed images were compared with the findings and pathological diagnoses obtained by surgical procedures.The conclusions were as follows:1) Plain CT demonstrated the location of the parotid tumor. Contrast enhancement seemed to delineate the margin of the tumor more clearly.2) By contrast enhancement, the branchiogenic cyst was differentiated from the parotid tumor, as a low density mass with an enhanced cyst wall.3) Parotid tumors enhanced by contrast material did not always appear as solid tumors.4) In some cases, CT numbers indicated the contents of the tumor.5) The extension of the tumor to the parapharyngeal space was clearly depicted on CT.6) It seemed to be difficult to evaluate the relationship of the parotid tumor to the facial nerve on plain CT.
