Ectopic Endometrial Tissue in the Thigh

Magnetic resonance neurography for the diagnosis of extrapelvic sciatic endometriosis

“…Manifestations at remote sites are termed extrapelvic endometriosis and present a particular diagnostic challenge because they often have unspecific or even distracting symptoms (12,13). Since the first report in 1946, it has been regularly appreciated in the literature that extrapelvic deposits of endometriotic tissue can occur along the sciatic nerve and cause neuropathic injury as observed here (1,14,15). During 4 years of inconclusive findings including laparoscopy, disabling pain and clinical signs of a sciatic neuropathy gradually developed in our patient.…”

Endometriosis in gluteus muscle with surgical implantation

“…No other patterns of occurrence could be found in the literature. Isolated cases have been described of endometriomas in the femoral vein at the saphenous opening (Recalde and Majmuder 1977), deep to the vastus lateralis muscle (Nunn 1949, Gitelis et al 1985, in the hamstring compartment of the thigh (Schlicke 1946, Giangarra et al 1987, surrounding the common peroneal nerve dccp to the lateral head of the gastrocnemius muscle (Pate1 et al 1982), and in relation to the forearm muscles (Biebl 1938, Navratil 1939. In only 1 of these cases was the endometrioma embedded in and surrounded on all sides by muscle (Giangarra et al 1987).…”

Sciatica in the female patient: anatomical considerations, aetiology and review of the literature

“…Typically, patients present with pain in the hip and the buttock radiating in the leg and foot that has its onset few days before menstruation and becomes progressively more severe, subsiding 2 or3 days to 2 weeks after cessation of menstruation; hence, the term cyclical or catamenial sciatica. As time goes on, the duration of sciatic discomfort may increase until it is constantly present with excruciating exacerbation during menses [14,25,26,28,35,39,44,45,49,50,55,58,63,69,73,75,77,113,124,133,140,143,144,146,147,154,156,158,160,164,167]. Diagnosis is usually late.…”
