Acute appendicitis-like symptoms as initial presentation of ovarian vein thrombosis

Postpartum ovarian vein thrombosis is a rare condition, with an incidence rate being 1/600 deliveries. It most often arises in the right ovarian vein. A 33-year-old patient who had had normal vaginal delivery presented with fever, pain in the right iliac fossa, and leukocytosis on the sixth day after delivery. An antibiotic course was instituted but 3 days later symptoms reappeared. Diagnosis of acute appendicitis was made. At surgery through a McBurney incision, a woody tumoration consistent with ovarian vein thrombosis was found. Anticoagulation therapy with heparin and antibiotics were instituted. Phlebography and color Doppler sonography confirmed the presence of thrombosis of both the common femoral iliac and inferior vena cava. Fribrolysis with urokinase was performed. The patient has remained stable and symptom-free over a 4-year follow-up. Ovarian vein thrombosis typically presents with symptoms suggestive of acute appendicitis, as was the case in our patient. Color Doppler sonography is the favored diagnostic procedure, with CT being a supplementary tool. Surgery is not necessary and treatment consists of anticoagulants and antibiotics. Even though postpartum ovarian vein thrombosis is rare, early recognition of the condition is of paramount importance to institute the adequate treatment and avoid potential serious sequelae.
