[Back pain].

Abstract

This 54 year old male patient complained of upper back pain for four months, which increased on physical exertion. An X-ray examination of the spine showed compression fractures of the anterior aspects of the thoracic vertebrae VI and XI as well as anterior aspects of the thoracic vertebrae VI and XI and signs of osteoporosis. Physical examination revealed signs of hypogonadism as well as eunuchoid disproportions of the skeleton. Serum tests gave evidence of a hypogonadotropic hypogonadism due to isolated LH-secretion deficiency (Pasqualini syndrome) with secondary osteoporosis.
