The computed tomographic (CT) features of pineal region tumors were analyzed in 60 histologically proven tumors. This is the largest reported series of histologically verified pineal region tumors studied with CT. The tumors were classified as germ-cell tumors, glial tumors, pineal parenchymal tumors, and meningiomas. Preenhancement germinomas revealed(More)
The computed tomographic findings in 14 cases of colloid cysts of the third ventricle are discussed. These tumors usually present as homogeneous, rounded lesions at the level of the foramina of Monro, with widening of the septum pellucidum. They are commonly hyperdense and show some enhancement upon injection of contrast material. The differential diagnosis(More)
The computed tomographic and angiographic features of 15 histologically proven primary extradural juxtasellar tumors were retrospectively reviewed. Five chordomas were characterized by prominent bone erosion and a significant posterior fossa component. Four trigeminal nerve neuromas each demonstrated bone erosion centered about Meckel's cave and moderate to(More)
Selective carotid angiography and computed tomography were used in a study of the association of occlusive vascular disease with cerebral arteriovenous malformations in 13 patients. The arterial occlusions ranged from focal stenosis in the major artery supplying the malformation to complete occlusion of the supraclinoid internal carotid artery with(More)
Computed tomograms, angiograms, and operative findings in 18 intra-atrial and 6 para-atrial lateral ventricle tumors were reviewed. Intra-atrial tumors were characteristically homogeneous, with an intraluminal mass effect. The benign types engulfed the choroid glomus; on angiography, the choroidal arteries were enlarged, with a definite tumor blush.(More)
Malignant tumors of the nasopharynx were analyzed by region of origin and route of spread. Nasopharyngeal carcinomas produced early submucosal infiltration of the deglutitional muscle layer with enlargement of the levator palati muscle and lateral displacement of the parapharyngeal space. Serous otitis media was frequently associated, and the trigeminal(More)
Forty patients with cervical myelopathy underwent high-resolution computed tomography (CT) with intrathecal administration of metrizamide for evaluation of cervical spinal cord atrophy. Thirty of them showed evidence of either focal atrophic distortion or generalized accentuation of the anatomic surface features of the spinal cord. Patients with a Chiari(More)
Delay in the diagnosis of meningiomas of the tuberculum sellae and planum sphenoidale is detrimental to the patient in terms of visual recovery, morbidity and mortality. Early accurate diagnosis of these tumors is possible through the use of computed tomography which is recommended for all patients with unexplained impairment of vision. In this article 105(More)
Ten patients with proven cerebellar hemangioblastomas were studied by computed tomography (CT). Angiography was obtained in seven cases. Eight patients had a cyst and a nodule, one presented with a nodule only, and one with a cyst only. Some morphological features on CT were found particularly helpful in establishing the histological diagnosis of this(More)
