Percutaneous transluminal angioplasty (PTA) is being extensively applied to treat arteriosclerotic lesions. However, this application has not been widely accepted for the treatment of carotid artery stenosis. Successful attempts to relieve cerebral ischemia from extracranial carotid arterial stenosis by PTA are reported. Twenty-seven patients with… (More)
Embolization of very vascular meningiomas prior to operation will reduce the loss of blood during operation. The technique of preoperative embolization is discussed, and 11 cases are presented.
PURPOSE To describe the MR imaging features of cerebellar medulloblastoma in the adult. MATERIALS AND METHODS The neuroimages and records of 15 adults with proved cerebellar medulloblastoma were retrospectively evaluated. In 12 patients, preoperative MR scans were reviewed; nine had Gd-DTPA-enhanced scans. RESULTS Of the 12 tumors evaluated… (More)
Therapeutic embolization is an effective and relatively safe method for managing many cases of head and neck trauma. In the last 5 years, 78 traumatic vascular lesions--10 arterial transections and 68 arteriovenous fistula--were treated by intravascular embolization at four medical centers. Selection of embolic materials is discussed and different types of… (More)
Three patients with progressive supranuclear palsy demonstrated atrophy of the midbrain, pons, cerebellum, and cerebral hemispheres by computed tomography with horizontal, sagittal, and coronal reconstruction. Benztropine therapy resulted in improvement of speech and gait without significantly affecting the vertical gaze palsy.
A 3-year-old boy with a septated syrinx and several other dysraphic features is presented. The literature regarding the cause, diagnosis, and pathology of septation in syringomyelia is reviewed. This case raises two points. First, the septated pattern may be associated with an elevated pressure in the syrinx. Second, despite the septations, the syrinx may… (More)
A patient with a congenital arteriovenous fistula between the middle meningeal artery and a cortical vein with a giant venous varix is described. The patient presented with an intracerebral hemorrhage that had been evacuated. Permanent cure of the fistula was achieved without morbidity by embolization with Ivalon particles.
Split notochord syndrome with dorsal enteric fistula is an extremely rare congenital anomaly that may be associated with meningomyelocele or meningocele, and genitourinary anomalies. This case presented with an additional finding of bladder exstrophy, raising the possibility of a relationship between this syndrome and the OEIS complex.
Adenocarcinoma of the prostate commonly metastasizes to lymph nodes and bones, with occasional visceral deposits; lesions in the brain are rare. Although leptomeningeal carcinomatosis secondary to prostatic tumor has been reported, discrete cranial dural metastases from prostatic adenocarcinoma have not been described previously. The case of a patient… (More)
