Giant retroperitoneal hemolymphangioma: A case report and review of literature

Figure 1 Computed tomography and 3D reconstruction images showing the volume reduction of the cystic mass before and after ultrasound-guided percutaneous nephrostomy. A large cystic mass was found around the left kidney. A: Preoperative sagittal computed tomography (CT) images; B: Preoperative CT coronal images; C: Preoperative three-dimensional coronal image; D: Sagittal CT images after drainage; E: CT coronal image after drainage; F: 3D coronal image after drainage; G: Sagittal CT images after surgery; H: Postoperative CT coronal image; I: 3D coronal image after surgery.

Figure 2 Presence of multiple solid cystic masses and cord-like tissues around the kidney. Dark red fluid was drained from the sac. A: Perirenal cyst solid mass; B: Multiple cord stripes.

Figure 3 Immunohistochemical staining of tissues dissected from the cystic mass. Some endothelial cells are relatively positive for CD34 and other cells are positive for D2-40. A: CD34 (vascular +); B: D2-40 (lymphatic +).
