Thirty-nine patients with histologically proved primary neoplasms, focal neurologic deficits, and positive CSF cytology were evaluated by enhanced cranial CT and MR, or complete myelography and MR of the spine. Intracranial abnormalities were noted on CT in 56% of cases and included abnormal enhancement of subarachnoid space and ventricular walls, ventricular dilatation, obliteration of cortica...

Subarachnoid hemorrhage (SAH) is bleeding into the subarachnoid space. It may result from a rupture of an intracranial aneurysm, bleeding from an arteriovenous malformation, hypertensive intracerebral hemorrhage with extension into the subarachnoid space, hemorrhage from an intracranial tumor, trauma, and hematologic disorders. If trauma is eliminated as a cause of SAH, more than 80% of SAHs ar...

We tested the hypothesis that cerebral arteriospasm developing after rupture of a subarachnoid aneurysm may be due to the vasoconstrictor effect of locally generated angiotensin II. Ten dogs had subarachnoid hemorrhage simulated by intracisternal introduction of 2 ml autologous blood, and were followed by cineangiography. Thirty minutes later, when acute arteriospasm was established, seven dogs...

We have examined the effect of extradual injection of 0.5% bupivacaine or normal saline on the progression of spinal anaesthesia in 28 patients undergoing Caesearean section. Three groups were studied. Subarachnoid anaesthesia was established in all patients. Group A (n = 10), the control, received no extradural injection for 20 min. Group B (n = 9) received extradural bupivacaine 10 ml and gro...

The increased density in the basal cisterns and the subarachnoid space on CT scans is a well-known characteristic of subarachnoid hemorrhage. Have been described diverse conditions that can emulate subarachnoid hemorrhage, such as purulent leptomeningitis, intrathecal contrast material and leak of high doses of intravenous contrast material to the subarachnoid space. We present the case of a ma...

One hundred myelographies with iopamidol and 100 with metrizamide were performed in order to compare the side effects of the two contrast media after injection into the spinal subarachnoid space. All patients were observed for a follow-up period of at least 4 days. The most frequently observed side effect, headache, was more common, of longer duration, and more severe with the use of metrizamid...

INTRODUCTION Myelograghy is a process of instilling contrast medium to the subarachnoid space for evaluating the spinal column by radiography. There are various contrast solutions for different radiographic studies but not all of them are suitable for spinal column evaluation. CASE PRESENTATION Our patient was a 60-year-old man who developed severe pain, tonic clonic convulsions and cardiopul...

Myelography of the entire spinal cord was performed in 64 consecutive patients using metrizamide via lumbar puncture. Adequate to good opacification of the cervical and thoracic subarachnoid space was obtained in 63 patients. The technical factors responsible for this success rate are patient cooperation, high iodine concentration, high iodine concentration (250 mg/ml), slow injection rate, del...

IMPLICATIONS Misplacement of an epidural catheter into the subarachnoid space is a recognized complication. However, breakage of an intrathecal epidural catheter during removal presents a dilemma. Appropriate imaging, a neurosurgical consultation, and aggressive surgical exploration and extraction of the retained piece are warranted, even in the asymptomatic patient.
