Hemolymphangioma is a malformation of the lymphatic and blood vessels. To the best of our knowledge, only a limited number of hemolymphangioma cases have been reported in the literature thus far, with no cases developed in the waist region. The present study reported the case of a 17-year-old male patient with hemolymphangioma growing on the waist, presented with back pain for four months. Upon physical examination, the lesion was identified to be oval in shape, soft and compressible, with mild tenderness. No abnormalities were detected in the results of laboratory examinations. However, a magnetic resonance imaging (MRI) scan revealed a tumor with low signal intensity on T1-weighted imaging (WI) and high signal intensity on T2-WI. The mass was successfully removed during surgery. During the seven-month follow-up period, the patient was asymptomatic with no evidence of recurrence. The present study discussed the imaging findings and pathological features of this uncommon case and reviewed the relevant literature.
