Generalised purulent peritonitis and small bowel obstruction due to a spontaneously perforated ovarian dermoid cyst.

We outline the narrative of a 28-year-old woman who initially presented to the emergency department with vomiting, diarrhoea, abdominal pain and fever. Blood tests revealed significantly raised inflammatory markers and acute renal failure. Initially, this was attributed to gastroenteritis due to a recent foreign travel, but further investigations and radiological imaging revealed a large right ovarian dermoid cyst with a significant amount of free intra-abdominal fluid and small bowel dilation.
