The case of a 73-year-old woman with a glossopharyngeal neuralgia due to compression of the 9th nerve by the lateral choroid plexus of the 4th ventricle excessively protruding through the foramen of Luschka is reported. No similar cases are described in the literature. Such an eventuality should be suspected and verified in the presence of a glossopharyngeal neuralgia in which no other causal factors can be demonstrated.

The hypophyseal gonadotrophin LH reserve was studied in 9 adult women, 5 of whom were suffering from nervous anorexia (N.A.) and 4 normal, by means of subcutaneous injection of 50 mcg of synthetic GN-RH. Basal values of plasmatic LH proved to be significantly lower in N.A. than in the controls where the response to GN-RH was prompt. In patients with N.A., on the other hand, response was practically absent and differences were significant at all stages of the test. The parallel study of basal steroiduria and following methopirone confirmed the torpid hypophyseal response in N.A. These findings confirm previous personal reports and indicate that the GN-RH test is a useful technique for diagnostic and prognostic definition of N.A.
The aetiopathogenesis and clinical and diagnostic features of bilateral absence of the testicles in 46XY subjects are briefly reviewed. A eunuchoid 25-yr-old patient with male sex chromatin, 46 XY genotype, plasma testosterone slightly below normal, normal urinary 17-KS unaltered by gonadotropin stimulation, and bilateral absence of the testicles is presented. Examination of the inguinal canal showed a funiculus and ductus deferens residue terminating in an adipose mass. Section of the fibrous duct showed that this mass was full of capillaries and venules. Lesion between the 14th and 16th week of pregnancy is postulated.
