Twisted Right Ovarian Teratoma Mimicking Ruptured Inflamed Appendix in a Young Woman

A 27‑year‑old female was referred to our health facility with a working diagnosis of a ruptured appendix on account of sudden onset of severe right iliac fossa and pelvic pain. Abdominal ultrasound scan, plain abdominal radiograph, and abdominal computed tomographic scans done in our health facility revealed a fairly rounded poorly vascularized right ovarian mass containing a tooth, fat, and Rokitansky nodule. A radiological diagnosis of matured poorly vascularized right ovarian teratoma with possible torsion was made. She had laparotomy with excision of the right ovarian mass, and the histology of the excised specimen confirmed the diagnosis of matured right ovarian teratoma. She responded well postoperatively, and subsequent follow‑up assessment was satisfactory.
