Calcified gliomatosis peritonei in a post-menopausal woman with mature ovarian teratoma.

Introduction: Gliomatosis peritonei (GP) is characterized by the presence of benign, mature glial implants in the peritoneum or omentum. Aim: Understanding unusual findings with clear knowledge of pathological comparisons makes diagnosis more reliable and guides future treatment. Case study: This is a case of a 70-years-old lady, post-menopausal, who presented with abdominal mass which progressively increased in size for the past 40 years. She also had constipation requiring laxatives and occasional lower abdominal pain. Her abdomen was clinically distended with a large hard central mass. Results and discussion: Computed tomography of the abdomen showed features of left ovarian teratoma with multiple gliomatosis peritonei. Histopathology of the mass post-surgery revealed a left ovarian mature cystic teratoma and the peritoneal deposits to be heavily calcified and fibrotic mature implants with no evidence of malignancy. Conclusions: Gliomatosis peritonei (GP) is a rare finding associated with ovarian teratoma and rare in postmenopausal women. It is important to appreciate a variety of radiological presentations of this condition to establish an accurate diagnosis. [ABSTRACT FROM AUTHOR]
