&NA;An exceptional combination of an intracranial convexity and two thoracic spinal meningiomas in a 17‐year‐old girl is reported. The small meningioma in the left central parasagittal region was removed. One year later, paraplegia rapidly developed. Two meningiomas (one of them ossified) about 2 cm in size were removed from the midthoracic level of the spinal cord. The distance between the two spinal tumors was about 2 cm. One and one‐half years after surgery the patient is well. The problem of multicentricity of meningiomas is discussed. (Neurosurgery25:447‐450, 1989)

摘要:

&NA;Spontaneous hemorrhage into the lateral part of the pons with sequelae compatible with survival has been documented previously. The author describes an unusual case with spontaneous hemorrhage into the lateral pons, with intraneural extension into the right trigeminal nerve root. Radiological features were of an expanding mass of the cerebellopontine angle. The patient was treated surgically with success. (Neurosurgery25:451‐454, 1989)

摘要:

&NA;The present study describes the phenotypic and functional analysis of tumor‐infiltrating lymphocytes isolated from a germinoma located in the pineal region. Tumor‐infiltrating lymphocytes were separated from the germinoma and cultured in medium containing IL‐2 (1000 U/ml). An immunohistochemical analysis of frozen sections revealed that 90% of the germinoma‐infiltrating lymphocytes were CD3‐positive T cells expressing CD4, CD8, and HLA Class I and Class II antigens, but were negative for CD16, CD20, CD23, CD25 and CD14 antigens. After in vitro cultivation in the presence of high concentrations of IL‐2, the lymphocytes proliferated for 2 weeks, showing marked DNA synthesis. In addition, the lymphocytes could lyse NK‐resistant allogeneic target cells. These results provide evidence for a potential role of germinoma‐infiltrating lymphocytes in vivo, and suggest that the lymphocytes may control the growth of autochthonous tumor cells by killing those that are not restricted to the major histocompatibility complex.

摘要:

&NA;A case of primary intrasellar germinoma in a 24‐year‐old woman is presented. Her initial symptoms were diabetes insipidus and headaches. The neurological examination found no abnormalities, but the endocrinological examination disclosed a deficiency in growth hormone secretion. Her skull x‐ray revealed a normal sella turcica, and a computed tomographic scan revealed no abnormal mass in the pituitary fossa, but a slightly enlarged stalk. Magnetic resonance imaging revealed a small tumor in the posterior lobe. Transsphenoidal exploration revealed a germinoma in the posterior pituitary lobe. Six cases of primary intrasellar germinoma, including our case, were reviewed. Our case is considered to be the smallest intrasellar germinoma yet reported. (Neurosurgery25:458‐462, 1989)

摘要:

&NA;Caudal regression syndrome involves absence of the sacrococcygeal vertebrae with or without lumbar vertebral defects. Since the neurological condition of infants with this syndrome deteriorates, radiographic studies are important to rule out any surgically correctable lesion. A paraplegic male neonate with a vertebral canal ending at T11 is presented. This is the first report of using magnetic resonance imaging to evaluate the spinal cord and surrounding soft tissues involved in this syndrome. Magnetic resonance imaging provides more anatomical details than myelogram with computed tomography, which greatly aids in determining whether surgery is necessary. (Neurosurgery25:462‐465, 1989)

摘要:

&NA;Two rare cases of cerebral cavernous angiomas in two infants. 9 and 6 months old, respectively, are reported and the other 11 cases in the literature concerning patients in the first year of life are reviewed. Cavernous angiomas of the brain occur rarely in the first year of life and present with seizures and head enlargement. On computed tomographic scan they typically appear as large, hyperdense, unenhanced masses, with large cysts and must be differentiated from tumors more common in infants, such as teratomas, ependymomas, and mixed tumors. Total removal is often possible, even with large lesions, because of the small amount of bleeding and the well‐defined limits of the mass. (Neurosurgery25:465‐469, 1989)

摘要:

&NA;An extremely rare case of a basioccipital meningocele causing obstruction of the upper airway in a neonate is described. A transoral approach was used to remove the meningocele and repair the dural fistula. Bilateral posterior lateral pharyngeal releasing incisions were made to allow mucosal and muscle coverage over the dural repair. This report demonstrates and emphasizes the use of lateral pharyngeal releasing incisions to cover midline full thickness defects in the posterior oropharyngeal wall that might be encountered during transoral transclival operations.

摘要:

&NA;A case of hereditary multiple exostoses with acute cervical myelopathy, tetraplegia, and apnea is reported. Neurological complications as a result of osteochondromas in hereditary multiple exostoses are rare. The majority of osteochondromas in the cervical spine arise from the neural arch. Magnetic resonance imaging and computed tomography are invaluable in localizing the origin of the lesion and its relationship to the spinal cord. Decompressive laminectomy usually results in excellent functional recovery. Where significant dorsal spinal cord compression exists without neurological deficit, prophylactic decompression can be recommended. (Neurosurgery25:472‐475, 1989)
