Unique partial duplication of the left ovarian vein: A case report

Partial duplication of the left ovarian vein is an extremely rare anatomical variation with significant clinical implications. We report the case of a 52-year-old female with no significant medical history, presenting with a 2-month history of vague upper abdominal pain. A diagnostic abdominal CT scan revealed an incidental finding of partial duplication of the left ovarian vein. The vein was enlarged, measuring 8 mm in diameter, and displayed a unique bifurcation at the lower end of the L4 vertebra, reuniting at the upper endplate of the L3 vertebra. Additionally, a short 4 mm segment connected the duplicated mid-segments. This case underscores the importance of thorough imaging and evaluation in identifying rare vascular anomalies, which can have significant implications for diagnosis and management.
