Ovarian Torsion with Resulting Constipation in a Panther Chameleon (Furcifer pardalis)

Abstract A 3-yr-old female panther chameleon (Furcifer pardalis) was presented with a history of long-term inactivity, anorexia, and difficulty defecating. Using sonographic examination, we diagnosed preovulatory follicular stasis with suspected ovarian cysts. Surgical management was elected, and the ovaries were intertwined and showed severe torsion and morphologic changes. The colon was caught within the entanglement, resulting in obstipation and urate retention. After ovariectomy, the animal was able to pass feces 17 h postsurgery and regained appetite. Preovulatory follicular stasis, as well as constipation, are commonly seen conditions in reptiles; however, torsions are rarely described.
