A Rare Case of Ligament Teres Cyst in A Neonate: A Tale of Successful Management

Falciform and ligament teres cysts are those arising due to congenital remnants either umbilical vein or mesenchymal elements. Asymptomatic to some extent, but can present directly with complications leading to morbidity and even mortality, hence justifying the need of surgery. Definitive diagnosis is by contrast enhanced computerized tomogram (CECT) and treatment is by open surgery or laparoscopic surgical resection with usually a good outcome. We report a 26-day-old female presenting with abdominal distension and irritability. Imaging revealed a cyst arising from the ligamentum teres. Surgical excision was performed, and histopathology confirmed a benign serous cyst. The infant recovered well and remained asymptomatic at 1-year follow-up. Early diagnosis and surgical management are key to favorable outcomes.
