Abstract
Lymphangiomas of the ovary are unusual benign tumours characterised by proliferation of lymphatic channels, composed of cystic spaces lined by a single layer of endothelial cells. We present a case of 61-year-old woman who presented with complaints of pain abdomen. Investigations revealed a large left ovarian multiseptate multiloculated cystic mass extending to pelvis, abdominal cavity and infraumbilical region likely neoplastic. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed suspecting malignancy. Histopathological examination revealed an ovarian lymphangioma.

Lymphangiomas of the ovary are unusual benign tumours characterised by proliferation of lymphatic channels, composed of cystic spaces lined by a single layer of endothelial cells
Ovarian cystic lymphangiomas must be included in the differential diagnosis of cystic ovarian masses and long term follow up is suggested to exclude a possibility of malignant transformation
Summary
Lymphangiomas are benign and slow-growing tumours of the lymphatic system [1] They are characterised by lymphatic proliferation and composed of multiple cystic spaces lined by single layer of flattened endothelial cells, which are separated by fibrocollagenous septae. Ultrasound whole abdomen showed a large pelvic and abdominal multiloculated cystic mass with eccentric solid tissue in the mid pelvis slightly inclined to the right side measuring 14.6 × 10.2 cm. CT abdomen showed a large multiloculated and multiseptated cystic mass measuring 13.2 × 12.18 × 11.5 cm involving the pelvic cavity and adnexa extending into the abdominal cavity up to infraumbilical region. Histopathological examination of the left ovarian cystic mass revealed multiple varying sized dilated vascular channels lined by a single layer of flattened endothelial cells without any atypia or hyperchromasia.
