Magnetic resonance imaging of the postoperative intervertebral disk: the first eight months--clinical and legal implications.

Ten patients were followed prospectively after lumbar discectomy, both clinically and with MR imaging, from 2 days to 8 months. The usefulness of MR imaging is limited during the first 2-3 months postsurgery because of severe disruption of the intraspinal anatomic definition. Thus, abnormal MRI findings during this initial period do not correlate with the clinical symptom-free state of patients postsurgery. The use of MR imaging in symptomatic patients is therefore limited.

Spontaneous retraction of cerebellar tonsils after surgery for Arnold-Chiari malformation and posterior fossa cyst.

Magnetic resonance images obtained before and 2 months after surgical decompression for Arnold-Chiari type 1 malformation and an arachnoid cyst revealed retraction of the cerebellar tonsils from the spinal canal into the posterior fossa. This was associated with prominent functional recovery of the patient's ataxia and nystagmus. Such an observation may reflect a benign prognosis. Magnetic resonance imaging is the test of choice for the evaluation of this type of lesion.

Surgical approach to the high subcranial internal carotid artery.

Two cases are presented to describe surgical approaches to the high cervical internal carotid artery permitting surgical treatment of conditions such as aneurysms of the high carotid artery, fibromuscular dysplasia, and arteriosclerosis by endarterectomy or resection of a segment with the interposition of a graft.

Late neurological dysfunction in adult lumbosacral lipoma with tethered cord.

The case of a 59-year-old man with adult-onset neurological dysfunction secondary to a tethered cord and a lumbosacral lipoma is presented. This condition not only affects children, but is known to produce neurological dysfunction in adults and should be kept in mind in the differential diagnosis of patients with sacral root deficits.

Acute epidural hematoma following epileptic seizures.

In cases of acute cranial epidural hematoma following trauma incurred during a major motor seizure, the symptoms and signs of the hematoma can be erroneously attributed to the postictal state. Since delay in diagnosis commonly leads to a poor or fatal outcome, an expanding mass should be suspected when status epilepticus, focal seizures, or postictal neurological deficits appear in an epileptic who has not previously had these symptoms.

Acromegaly: analysis of 132 cases treated surgically.

The surgical treatment of 132 acromegalics is analyzed. There was an equal sex distribution among patients between the ages of 30 and 59. In the younger patients there was a preponderance of males, and the opposite situation occurred in patients older than 59 years. The overall cure rates were 58% (growth hormone (GH) less than 5 ng/ml) and 78% (GH less than 10 ng/ml). Endocrinological evidence of cure was observed most commonly in patients who exhibited preoperative GH values below 70 ng/ml.

Undecussated innervation to the sternocleidomastoid muscle: a reinstatement.

Clinical evidence is presented to support the contention that the sternocleidomastoid muscle is innervated primarily by undecussated fibers from the ipsilateral hemisphere. Stroke patients often show contralateral hemiparesis accompanied by weakness in head turning to the side of the paresis.

Endocrine outcome after transsphenoidal adenomectomy for prolactinoma: prolactin levels and tumor size as predicting factors.

The level of prolactin in the serum was determined pre- and postoperatively in 90 patients who were operated upon transsphenoidally for prolactin-secreting pituitary adenomas. Twenty-three had microadenomas and 67 had macroadenomas. Those patients who were cured had a distinctly lower mean prolactin level (about 200 ng/ml or less) than those who were not cured. Of those patients whose adenomas were larger than 10 mm in diameter, only 39% were cured. The relationship between prolactin levels and tumor size and the return of menses and cure is discussed.

The specificity of serum prolactin as a diagnostic indicator of pituitary adenoma.

Serum prolactin levels were determined in 205 patients with a variety of intracranial diseases, including 70 cases with pituitary tumors. It is concluded that although the absence of elevated prolactin levels does not help to rule out pituitary pathology, the presence of hyperprolactinemia is highly specific for diseases of the pituitary and hypothalamus, and prolactin determination should be part of the regular work-up of pituitary tumor suspects. Excluding known causes of hyperprolactinemia, such as tranquilizing drug ingestion, the presence of neurological disease outside the hypothalamic-pituitary area was not associated with increased serum prolactin concentrations.

Precocious puberty of cerebral origin.

Eighty-two cases of precocious puberty of cerebral origin were reviewed. All shared as a common factor the distortion, compression, or destruction of diencephalic structures. Attempts were made to parallel basic research findings with those derived from human pathology, hoping to gain further insight into the physiopathology of precocious puberty of cerebral origin.

Organismic states and their effect on recovery from neurosurgery: a new perspective with implications for a general theory.

The authors examine and review current research on recovery of function following brain damage. Emphasis is placed upon the physiological and neurochemical states of the organism prior to neurosurgery and their influences on behavioral recovery of function. It is proposed that the consequences of a given neurosurgical procedure depend not only on its neuroanatomical locus but also on the organismic state of the brain substrate at the time of such a procedure. The brain substrate can be modified prior to a given manipulation, resulting in an alternation of the effects of the manipulation. The implications of this new perspective for both basic research and clinical medicine are discussed.

Hyperdipsia associated with hypothalamic-midbrain hemorrhage.

A case of diencephalic-midbrain hemorrhage presenting with excessive thirst, coma, and death is discussed. Some diencephalic dysfunction syndromes are reviewed, as well as their physiological basis. Thirst and drinking behavior can provide a valuable localizing symptom and sign in clinical-pathological correlations.
