Mesial temporal sclerosis detected by computed tomography.

We report a case of an epileptic patient in whom unilateral mesial temperal sclerosis was detected by computed tomography in the form of an arcuate, nonenhancing calcification. Temporal lobectomy was followed by relief of the seizures.

Prognostic value of EEG in acute vascular aphasia: a long term clinical-EEG study of 53 patients.

A group of 53 patients rendered acutely aphasic by occlusive cerebrovascular disease were studied by serial EEG's, repeated neurologic examinations and speech evaluations (Porch Index of Communicative Ability) over a period of eight to twenty-four months, in order to correlate EEG findings with the degree of language disorder and prognosis for language recovery. Normal and mildly abnormal EEG's, posterior slow foci, focal slowing of semirhythmic type and higher alpha frequencies over the intact hemisphere correlated with good language recovery. In the majority of the patients, the curves of "EEG Improvement" and "Language Recovery" closely paralleled each other. These data indicate that the EEG is of prognostic value as to recovery from aphasia in patients suffering from acute occlusive cerebrovascular disease. Despite the advent of newer diagnostic tests, such as CAT scan, which has established its value in evaluation of the anatomy of aphasia, (9) EEG remains to be useful as a tool that could predict the outcome of aphasia in stroke patients.

Surgically correctable lesions detected by CT in 143 patients with chronic epilepsy.

CT findings justified surgical intervention in four young patients who had suffered from intractable epilepsy for many years. Previous non-invasive and invasive neurodiagnostic procedures with these patients had failed to show focal cerebral lesions amenable to surgical treatment. All four patients achieved significant relief from seizures after the operations.

Spinal cord compression due to pseudomonas in a heroin addict. Case report.

Involvement of the spinal cord has not been reported in osteomyelitis of the spinal column caused by Pseudomonas aeruginosa. Cerebrospinal fluid findings have been reported only once in osteomyelitis of the spine by this agent. Our patient had persistently increased cerebrospinal fluid protein during an acute episode of cervical spine osteomyelitis, characterized by fever and neck pain. Roentgenograms of the cervical spine and neurologic examination did not show any definite abnormality. He became paraplegic 18 months later, after having symptoms of numbness of the feet and progressive weakness of the legs for 1 month. A surgical procedure and antibiotic treatment resulted in remarkable recovery. A bone specimen grew P. aeruginosa.

Brown-Séquard syndrome and cervical spondylosis.

Six patients with a rapidly progressive myelopathy of the Brown-Séquard type are presented (two in detail). Their clinical history, results of laboratory investigations, and surgical exploration revealed cervical spondylosis as the sole cause of this syndrome. We believe that a rapidly progressive myelopathy of Brown-Séquard type even in younger individuals, is often a presenting clinical feature of cervical spondylosis.

Leptospirosis: a neglected cause of nonbacterial meningoencephalitis.

Two cases of leptospirosis with different clinical presentations are presented. The importance of recognizing mild, nonicteric and meningoencephalitic forms in order to identify vectors and contaminated areas and prevent further infections is emphasized. Cerebrospinal fluid (CSF) findings in reported cases of leptospirosis are reviewed and possible prognostic implications of CSF xanthrochromia, hypoglycorrhachia, persistent polymorphonuclear leukocytosis, and increased intracranial pressure are discussed.

Somatosensory evoked potentials and magnetic resonance imaging in intraspinal neoplasms.

Median and posterior tibial somatosensory evoked potentials (SEPs) were studied on 25 patients with pathologically proven intraspinal neoplasms, and the results were compared and correlated with the details of clinical examination and the information derived from magnetic resonance imaging (MR). MR was abnormal in all cases and in 23 of 25 (92%) demonstrated an intraspinal expansile lesion. SEP was abnormal in 19 of 25 patients (76%). Abnormal SEPs were found in 18 of 19 patients (94%) with cervical or thoracic neoplasms but only in 1 of 6 patients (16%) with the tumor in the thoracolumbar or lumbar region. SEP-MR correlation was significant (P less than 0.05) for thoracic intraspinal neoplasms where all 9 had an abnormal SEP showing a similar pattern of normal median and abnormal posterior tibial study. Clinically, all 7 patients with posterior column sensory deficits had abnormal SEP (100%). Abnormal SEPs were seen in 7 of 11 (63%) patients with spinothalamic deficits and in 4 of 8 (50%) of those with normal sensory examinations. Four of 9 patients (44%) with a normal neurological examination or an examination disclosing ambiguous results indistinguishable from a peripheral pathology had an abnormal SEP strongly suggesting a central sensory disorder. Comparison of preoperative and postoperative SEPs did not disclose useful prognostic information pertaining to the functional recovery.

Somatosensory evoked potentials and magnetic resonance imaging in syringomyelia.

Somatosensory evoked potentials (SEPs) to median and posterior tibial stimulation were obtained in 22 patients with syringomyelia. All patients had magnetic resonance imaging (MR) which defined the maximum transverse diameter of the syrinx as well as its longitudinal extension. SEP was abnormal in 16 (72%) patients. Median and posterior tibial SEPs were abnormal in 11 and 15 patients respectively. Both tests were abnormal in 10 patients. Ten patients showed absence of one or more central potentials (P/N13, N20, N22) and 7 patients demonstrated increased conduction times (N9-N20, P/N13-N20, N22-P40). The mean maximum transverse diameter of the syrinx was 7.5 mm in patients with normal SEPs and 16.2 mm in patients with abnormal SEPs. Abnormal SEP was observed in all 5 patients with loss of position sense, in 9 of 13 (69%) with loss of superficial pain and temperature, and 1 of 2 patients with motor deficit only. Central SEP abnormalities were observed in 3 of 5 patients with sensory deficits indistinguishable from a peripheral neuropathy and in 2 patients in the asymptomatic extremity. Three of 4 patients with syringomyelia and Chiari malformation had a normal SEP.

Gaze-evoked visual seizures in nonketotic hyperglycemia.

Focal motor seizures are commonly a symptom of nonketotic hyperglycemia (NKH). Posture-induced motor seizures are less common but have been reported in some patients with this disorder. We report the first case of gaze-evoked sensory (visual) seizures in nonketotic hyperglycemia. Both seizures and ictal EEG findings disappeared shortly after hyperglycemia was corrected.
