Two hundred and two patients were referred to the ultrasound department for evaluation of a pelvic mass during 1977, and of these only 120 underwent an operation enabling a definitive diagnosis to be made. The diagnostic accuracy of ultrasound was compared with the final operative diagnosis. The great majority (98%) of pelvic masses could be detected, and ultrasound was accurate in predicting the antatomical site of a pelvic lesion in 88% of cases. Uterine lesions were precisely diagnosed in 87% of cases, but only 30% of adnexal conditions could be specifically recognized. Numerous situations in which ultrasound provided additional information of great clinical value were noted.

In three and half years at the Ahmadu Bello University Hospital, Zaria, Nigeria, endometriosis was found in 27 Nigerians (all negroid) and one Caucasian. Age and parity distribution were similar to what has been found in patients elsewhere. In other respects, there were striking differences. The frequency (8.2 percent) is one of the highest reported in the negro. Two fifths were menopausal, majority had associated pelvic inflammatory disease, and nearly all were in women of the lowest socio-economic status. The lesions were rare in the pouch of Douglas and were totally absent from the rectovaginal septum and in the extra peritoneal space.
