[Case of calcified prolactinoma combined with Rathke's cleft cysts].
A case of chromophobe adenoma with capsular calcification combined with Rathke's cleft cysts is presented. A 28-year-old woman presented with a seven-year history of amenorrhea. Several months before admission to our department of neurosurgery on November 6, 1982, she developed galactorrhea and difficulty in reading because of visual failure. Neurological examination on admission revealed bitemporal hemianopsia, visual disturbance, left optic atrophy. Plain skull films and CT scan showed suprasellar capsular calcification. The patients hormonal status was assessed pre- and postoperatively. The basal serum prolactin (PRL) level was elevated at 790ng/ml, but other hormone basal plasma levels were within normal limits despite decrease in FSH, LH, The LH, FSH and PRL demonstrated a blunted response to LH-RH (100 micrograms). Both TSH and PRL demonstrated a blunted response to TRH (500 micrograms). The GH showed no response to insulin tolerance test (0.1 U/kg). On November 24, right frontal craniotomy was performed. A grayish bulging mass was noted surrounded by a calcified layer(2-3 mm) in the suprasellar region. When incised this calcified hard layer, showed multi-small cysts with yellow fluid. Under the cyst layer, there was a soft mass which was curetted easily. Histologically, under the ossified layer, there were multi-small cysts, lined by a single layer of ciliated columnar epithelium. The central soft mass was regarded as a chromophobe adenoma with no calcified body. Following partial removal of the tumor, there was prompt improvement in clinical signs and plasma PRL level.(ABSTRACT TRUNCATED AT 250 WORDS)
