ABSTRACT

Unilateral ovarian torsion was diagnosed in two unrelated iguanas based on gross and microscopic findings. Case No. 1 was an adult female green iguana, Iguana iguana, that died with severe egg retention and systemic bacterial infection with unilateral granulomatous oophoritis and a 360° clockwise torsion of the left ovary. Case No. 2 was a two year-old female rhinoceros iguana, Cyclura cornuta, that died after a seven day history of marked weakness, lethargy, anorexia and tremors, and had a 270° counterclockwise torsion in the right ovary with oophoritis and a coelomic serosanguineous effusion. This is believed to be the first report of ovarian torsion in iguanas, although follicular torsion has been recently documented in a green iguana.
