Abstract

Spontaneous rupture of mature cystic teratoma is a rare complication which results in leakage of the liquefied sebaceous contents into the peritoneum leading to acute or chronic peritonitis. We report a case of a 23-year-old female who presented with pain abdomen, abdominal distension and fever. Contrast enhanced abdominal CT scan showed right adnexal complex cystic lesion with discontinuity in its wall along with features of peritonitis.

Highlights

Dermoid is the most common ovarian neoplasm comprising between 10 to 25 percent of ovarian tumours
We present the CT findings of a case of spontaneous rupture of mature cystic teratoma causing chemical peritonitis
On USG there was a cystic lesion of size ~6x5.5cm in right adnexal region with internal echoes and septations within along with mild fluid collection with internal echoes in abdomen and pelvis

Summary

Introduction

Dermoid is the most common ovarian neoplasm comprising between 10 to 25 percent of ovarian tumours. The tumor can rupture causing leakage of the sebaceous contents into the peritoneum and resulting in peritonitis. This is a rare complication, occurring in less than 1% of cases.[1] We present the CT findings of a case of spontaneous rupture of mature cystic teratoma causing chemical peritonitis.
