[NONSENSE MUTATION 193C>T OF NEUROFIBROMATOSIS TYPE 2 - A NEUROSURGICAL CHALLENGE]

BOBEST Mátyás, TÓTH Csaba, GYURCSÓ Mária, MOLNÁR Mária Judit, GARZULY Ferenc

[A 15 years old male was operated because of incidentally found intercostal schwannoma. Two years later severe cerebellar ataxy and left sided anacusis developed. MRI revealed bilateral vestibularis tumors and multiple cervical intradural extramedullar myelon compressing lesions. After partial resection of the huge left sided cerebello-pontin tumor, histologically schwannoma, and the exstirpation of the multiple cervical meningiomas the patient died three months later due to septic complications. The 24 years old mother had been operated on similar lesions 12 years earlier, after two weeks postoperative period she died. Her 14 years old twins are living, a boy also with bilateral acustic tumours and a girl who is intact. Genetic investigation revealed C>T nonsense mutation at position 193 in the exon 2 of the NF2 gene. This mutation cause premature truncation of the gene protein and is probably in connection with the clinically severe phenotype. Early diagnosis of this type of neurofibromatosis is mandatory concerning the therapy.]

[A CASE OF SCHIZENCEPHALY WITH POLYMICROGYRIA]

LEEL-ŐSSY Lóránt, SZŰCS Iván, ALMÁSI Kálmán

[A case of extensive bilateral frontotemporal schizencephaly is alleged - more extensively in the left hemisphere - which associated with polymicrogyria. The cortical anomaly was discovered only incidentally by MR examination in a 22 year-old man who suffered from headache due to a mild head trauma. Neurological examination proved to be negative. He had no complaints or symptoms a few weeks later. The developmental anomalies in corticalisation are shortly overviewed in this group together with the possible causing factors. It has been emphasized the importance of the precise intrauterine and/or postpartum differential diagnosis between schizencephaly, porencephaly and other failure in corticalisation.]

[UNCOMMON MANIFESTATION OF CENTRAL NERVOUS SYSTEM SARCOIDOSIS]

RÓZSA Anikó, SZTANKANINECZ Yvette, GÁCS Gyula, MAGYAR Tamás

[Two cases of uncommon manifestation of central nervous system sarcoidosis are reported. A 42 year-old man had a spinal cord sarcoidosis. MRI of the spinal cord showed myelopathy in the cervico-thoracic region, and the T2-weighted image showed increasing signal intensity. Neurological symptoms did not correllate with radiological abnormalities. Neurological manifestation was paucisymptomatic. Half a year later steroid and azatioprin therapy led to almost complet radiological and clinical regression. In the second case we present a 49 year-old woman who had left side internuclear ophthalmoplegia and the brainstem lesion. The patient was proven to have sarcoidosis. In this case no abnormalities were found in brain MRI. Neurological symptoms could not be detected by MRI, probably caused by brainstem parenchymal lesions consisting of microgranulomatosis that is sarcoid "brainstem encephalitis". Neurological symptoms improved after steroid treatment in this case too. In both of the cases pulmonary lymphadenopathy helped to diagnose sarcoidosis. In our cases there were interesting correllations between neurological symptoms and MRI abnormalities. At the spinal cord sarcoidosis the radiological abnormalities were more striking than the clinical manifestation. In the other case we found distinct brainstem symptoms but could not detect MRI abnormalities.]
