Struma ovarii


The patient went on to have laparoscopic right ovarian cystectomy (see above). Operative notes revealed a 7 cm right ovarian cyst, with contents which macroscopically appeared consistent with a dermoid. There was associated 180 degree ovarian torsion, without fully cutting off the blood supply. The cyst was excised in its entirety.

Histopathology revealed struma ovarii with focal squamous differentiation (see above).

The patient was subsequently recalled for laparoscopic right salpingo-oophorectomy, with no evidence of residual tumor or malignancy on histopathology. Pre-operative serum TSH was normal.
