Duplex collecting system is a common congenital urinary system anomaly and is usually asymptomatic. Vascular variations associated with a duplex system are common but haven't been reported as obstructive. 14-month-old female had a right sided incomplete ureteral duplication complicated by lower pole hydroureteronephrosis due to distal ureteral obstruction by an aberrant vessel crossing the bifid ureters at ureteric junction of these bifid ureters. Prenatal imaging detected right hydronephrosis. Magnetic resonance suggested a diagnosis of duplicated ureters. At surgery, an aberrant artery compressed the lower moiety ureter at the bifid ureteric junction. The stenotic section was resected and ureter segments were anastomosed. The occluding small artery was not resected to preserve vascularization. An anatomical vascular variation can cause proximal ureteral dilatation and segmental hydronephrosis in a bifid system.

Introduction: Lymphangiomas are benign tumors/malformations, characterized by proliferation of the lymphatic vessels. They may arise anywhere, although the most common localizations are the head-neck region and the axilla. To date, only 21 cases of lymphangioma of the ovary in a 60-year literature survey have been reported. Case report: A 16-year-old female patient with long standing abdominal distension had 40 cm × 15 cm × 29 cm ovarian lymphangioma. Conclusions: Our case highlights that lymphangiomas can occur in the adolescent population and should be added to the differential diagnosis of ovarian masses in this age group. [ABSTRACT FROM AUTHOR]
