Extraperitoneal lymphangiomas are rare and usually asymptomatic. The incidence retroperitoneal lymphangiomas is approximately 1%. The symptoms often depend on the location of the tumor and the tumor size. We’d like to share a case in Chi-Mei hospital.
A 47-year-old man suffered from urinary frequency and nocturia for 2 years. The symptoms worsened recently. Physical examination found low abdominal dullness and palpable mass without tenderness. Sonography found post-voiding residual urine 914ml. Abdominal CT showed a huge cystic lesion in lower abdomen with compression to urinary bladder and bilateral ureter. The patient then received surgical excision of the tumor. During the surgery, a huge cystic lesion containing 3100cc fluid with adhesion to urinary bladder, left external iliac vessels, and obturator nerve was found, and was removed smoothly. The post-operative pathology reported in cystic lymphangioma. The patient’s post-operative condition remained fine, and no complication was noted.
