PERITONEAL STRUMOSIS; SIX YEARS AFTER LAPAROSCOPIC OVARIANCYSTECTOMY - A CASE REPORT

Abstract

Peritoneal strumosis or Struma ovarii with peritoneal dissemination is a rare presentation of extra-ovarian struma ovarii with benign thyroid histology. Here we describe a rare case of peritoneal strumosis which occurred six years after laparoscopic ovarian cystectomy. A 30-year-old P1L1 woman presented with complaint of abdominal distension for three years. She had history of laparoscopic surgery six-years ago for left ovarian tumour and its histopathology report revealed struma ovarii. On examination, the patient had an irregular large mass of about 20 weeks gravid uterus size. On per vaginal examination, a mass of mixed consistency occupied the whole of the posterior fornix. Ultrasound and contrast-enhanced computed tomography (CECT) pelvis were done. All tumour markers and thyroid function tests were within the normal range. The patient was taken up for staging laparotomy in which multiple nodules ranging from 2 to 10 cm were found in the omentum, in relation to the gut, bladder, ovary, and uterus. Histopathology confirmed the diagnosis of benign peritoneal strumosis. Conclusively, we must exercise caution to avoid spillage of any ovarian tumour while handling it.
