Case report reveals renal lymphangioma misdiagnosed as a renal cyst in an adult, suggesting the need for careful evaluation.
Renal lymphangioma is rare in adults and easily misdiagnosed due to non-specific clinical and imaging features. A 49-year-old Chinese male was admitted after routine physical examination detected a right renal cyst, with CT indicating a cystic lesion. He underwent laparoscopic surgery, and postoperative pathology confirmed renal lymphangioma. No recurrence was noted during 16-month follow-up. Clinicians should maintain high suspicion for this entity when evaluating adult renal cystic lesions, as pathological examination is the gold standard for diagnosis and surgical intervention yields favorable outcomes.
