Pneumatosis cystoides-like pattern is a group of histopathological features occasionally found in ovarian teratomas. This is a case of laparoscopic ovarian cystectomy performed for incomplete adnexal torsion where histology reported mature ovarian teratoma with “pneumatosis cystoides-like appearance”. This term is used to describe the presence of multiple cystic spaces within the tumor wall. It has been reported also in other organs, such as gastrointestinal tract, urinary bladder and the vagina. It may be secondary to mechanical, bacterial or ischemic causes, with the pathogenesis remaining unclear. It is benign and may exist more often than reported.

Keywords: teratoma, ovary, pneumatosis cystoides
