Toxemia of pregnancy: cerebral CT findings.

Four patients with pregnancy-induced hypertension (preeclampsiaclampsia) and neurological dysfunction unrelated to intracranial hemorrhage, cerebral venous thrombosis, or preexisting neurological disorder had cranial CT performed during their hospitalization. Three patients had diffuse white matter hypodensities with associated mass effect. The fourth patient had bilateral, asymmetric hypodensities confined to the basal ganglia. Computed tomography is useful in establishing an early diagnosis of the complicating neurological disorder as well as in providing a better understanding of the physiopathological changes seen in the brain in this condition.

Long survival of primary cerebral lymphoma with progressive radiation necrosis

A 56-year-old man lived 8 years after excision and irradiation of a primary cerebral lymphoma. Delayed radiation necrosis caused progressive neurologic deterioration and probably his steroid-responsive episodes of obtundation. Vasogenic edema induced by radiation may account for the latter. An incidental extraneural lymphoma was found postmortem without evidence of CNS lymphoma.

Radiologic evaluation of tuberculous meningitis.

Five cases of primary tuberculous meningitis are presented. In three cases of acute meningeal process, the classic computed tomographic (CT) scan findings of basal meningeal enhancement, hydrocephalus and arteritis on angiography were found. These radiologic findings suggested the diagnosis, and antituberculosis treatment was therefore instituted at an early stage of the disease. In the remaining two cases with late complication of tuberculous meningitis, hydrocephalus and basal vessel arteritis were present. The importance of correlation of the clinical and radiographic findings is discussed.

Rhinocerebral mucormycosis with ct scan findings: A case report

A case of rhinocerebral mucormycosis in a diabetic patient is presented. The radiologic findings of the disease with differential diagnosis are reviewed. Almost complete cure with surgical excision and Amphotericin B was accomplished.

Computed tomography of the brain following radiation and chemotherapy: Preliminary report

Abstract Pre-treatment and post-treatment CT scans of the brain in 94 patients with brain tumors have been reviewed. The CT scan changes of the brain following chemotherapy, radiation therapy or both have been evaluated. In 61% of the patients with primary brain tumors and 48% of the patients with metastatic brain tumors, CT scans demonstrated atrophic changes, leukoencephalopathic changes or a combination of both.

Hydrocephalus following iophendylate injection myelography with spontaneous resolution: case report and review.

A 62-year-old patient developed severe adhesive spinal arachnoiditis and hydrocephalus with papilledema following iophendylate injection myelography. Papilledema and hydrocephalus resolved spontaneously. The possible mechanism for hydrocephalus is discussed and the literature reviewed.

Importance of metrizamide CT for evaluation of the thoracic spine

Post-metrizamide myelographic CT of the area of interest is indicated in cases in which myelography is normal, and also in cases in which myelographic findings alone cannot explain the patients symptoms. Obtaining early and 4-6 hour delayed CT is of great importance for the detection of syringomyelia and cystic lesions of the cord. In cases of congenital anomalies, additional information can be obtained by this method. This paper presents our experiences at Loyola University Hospital.

CT demonstration of a dural arteriovenous malformation

A case of dural arteriovenous malformation with intracranial and subdural hemorrhage is presented. The computed tomographic scan with contrast injection demonstrated nodular enhancement adjacent to intracerebral hemorrhage, suggesting an underlying vascular malformation. Angiography confirmed this suggested diagnosis. A brief review of dural AVM is included.

Prolonged Retention of Contrast Medium in an Hypoxic Neonatal Brain

A neonate with hypoxic damage to the brain from a complicated pregnancy and delivery demonstrated a prolonged retention of contrast medium in her cerebral dural veins and brain substance after cardiac catheterization. Myoclonic status epilepticus began during injection of the contrast medium and persisted until its clearance as noted by CT scan. A postmortem examination did not reveal any vascular or congenital abnormalities that would account for these effects.

Cerebrospinal fluid rhinorrhea with bilateral intradiploic epidermoid tumors: a case report.

Bilateral large intradiploic epidermoid tumors of the occipital bone presented clinically with CSF rhinorrhea are presented.
