RT Journal Article SR Electronic T1 A giant ganglion cyst of hip joint causing lower limb edema JF Saudi Medical Journal JO Saudi Med J FD Prince Sultan Military Medical City SP 569 OP 571 VO 31 IS 5 A1 Gong, Weihua A1 Ge, Fangmin A1 Chen, Li YR 2010 UL http://smj.org.sa/content/31/5/569.abstract AB Lower limb edema caused by a giant ganglion cyst of hip joint, rather than deep venous insufficiency or lymphedema, is unusual particularly for guiding clinical practice. In this study, we present a rare case of a 76-year-old man with a 3-month history of progressive swelling of right lower extremity and 2-month history of a known inguinal mass, which was initially thought as hemangioma by using ultrasound. But, subsequent computed tomography examination and exploration surgery revealed a giant ganglion cyst compressing the right femoral vein. Resection of the cyst led to complete resolution of symptoms postoperatively. To the best of our knowledge this is a very rare case of giant ganglion cyst of hip joint origin causing lower limb edema in the literature.
