A case of ovarian vein thrombosis in a patient with extensive stage small cell lung cancer with metastasis to the pancreas.

Ovarian vein thrombosis is a well-known but rare entity, which is most often diagnosed during the postpartum period. It has also been reported to be associated with inflammatory and malignant processes within the abdomen and pelvis. We report an unusual case of ovarian vein thrombosis in a patient with extensive stage small cell lung cancer with metastasis to the pancreas. This diagnosis should be considered in the differential diagnosis for pelvic pain in a patient with primary or metastatic intra-abdominal/intra-pelvic malignancy.
