A 14-year-old girl, whose birth and developmental history were normal till the age of 7, was admitted to our hospital because of slowly progressive difficulties in walking, speaking and hearing. She also complained of absence of menstruation. She showed poor school records since the age of 7. On neurological examination, she showed limb and truncal ataxia. There was no nystagmus but slurred speech was found. Muscular power was good and her sensory system was normal. Tendon reflexes were equally present, and plantar reflexes were flexor. Bilateral moderate nerve deafness was also present. Mental deficiency was diagnosed on an intelligence test. Brain CT and MRI showed cerebellar atrophy. Gynecological examination revealed scanty pubic hair and small uterus. Karyotype was 46XX. Endocrinological studies demonstrated high level of FSH, low level of E2, and the normal response to pituitary stimulation with LHRH, indicating the existence of primary hypogonadism. Although the etiology of this multisystem disorder is unknown, it is possible that both nervous and endocrine disorders were genetically determined.

A 1-year 11-month-old girl was admitted for losing her weight and gait disturbance. At 4 months of age, she began to become emaciated inspite of normal food intake. Physical and neurological examinations were normal except for a marked lack of subcutaneous fat, irritability and nystagmus. CT scans demonstrated a large tumor occupied in the third ventricle and marked dilatation of the lateral ventricles. Endocrinological studies revealed high levels of plasma growth hormone (GH) in contrast with normal levels of somatomedin-C. The basal value of GH returned to normal with a subnormal response to insulin subsequently after VP-shunt. Then, a pilocytic astrocytoma was partially resected with transcallosal approach. Postoperative course was uneventful and her growth rate returned to normal range. CT scans after radiation therapy of 49 Gy showed marked decrease in size of the tumor. At 3 years and 6 months of age, enlargement of her breast was pointed out although MRI indicated no enlargement of the tumor. Basal value of LH, FSH, E 1 and E 2 elevated and LHRH test showed over-response of LH and FSH. Other hypothalamic-pituitary functions were partially preserved. Case of precocious puberty following diencephalic syndrome associated to the hypothalamic and/or optochiasmatic glioma is quite rare in the previous literature. Mechanisms of diencephalic syndrome and following puberty are unclear. However, endocrinological and radiological findings observed in the present case suggest that hormonal disfunction might be due to the failure of inhibition on GH and LHRH secretion mechanism in the anterior hypothalamus.
