“…In terms of the tumor capsule, most reports have shown no presence of capsules in AH. Similar to only a few previous reports [ 17 – 19 ], our case had a complete capsule. Unfortunately, the studies that have reported tumor capsules did not show imaging findings.…”

Imaging findings of retroperitoneal anastomosing hemangioma: a case report and literature review

Background Anastomosing hemangioma is an uncommon benign vascular tumor that may be mistaken for a malignancy. The imaging findings of anastomosing hemangioma are not well provided from the previous reports. Herein, in the study, we discuss the imaging findings for one case of retroperitoneal anastomosing hemangioma. Case presentation One 64-year-old female patient had a left retroperitoneal mass that was incidentally detected upon physical examination. A hypoechoic mass with abundant blood flow signals was found by US in the perirenal space. CT and MRI detected a large cystic and solid lesion in the left retroperitoneal space. Plain CT indicated that the internal density was uneven, and the pattern of enhancement was obvious and progressive. MRI-T2WI showed high intensity, DWI showed isointensity, and the mass also showed obvious progressive enhancement. Finally, anastomosing hemangioma was diagnosed via histopathological studies. Conclusion As a rare and benign tumour, anastomosing hemangioma is easily misinterpreted. We suggest that the observation of “genitourinary tract related, well defined, hyperintensity or isointensity on T2WI, isointensity on DWI, and obvious progressive enhancement patterns likely to the vascular enhancement” may consider the diagnosis of AH.

Primary vascular tumours of the kidney are rare and may pose diagnostic difficulties because of their similar clinical, morphological, and immunohistochemical features. This article summarizes the clinical and pathological features of primary renal angiosarcoma and anastomosing haemangioma of the kidney including epidemiology, genetics, and prognosis. Renal anastomosing haemangiomas are benign neoplasms characterized by anastomosing capillary-sized vascular channels. These tumours are rare, with about 75 cases reported in the literature. Most anastomosing haemangiomas are found incidentally on ultrasound, computed tomography, or magnetic resonance imaging. Common symptoms include abdominal pain, haematuria, and abdominal mass. Renal anastomosing haemangiomas are characterized by recurrent mutations in GNAQ and GNA14 genes. The prognosis of anastomosing haemangioma is excellent. Primary renal angiosarcomas are malignant tumours showing endothelial differentiation. To date, 76 cases have been described in the literature. Primary renal angiosarcomas are frequently symptomatic. The clinical features of renal angiosarcomas are similar to those of renal anastomosing haemangiomas, including abdominal pain, haematuria, and abdominal mass. Angiogenesis-related genes and vascular-specific receptor tyrosine kinases such as KDR, TIE1, SNRK, TEK , and FLT1 are upregulated in angiosarcomas. Primary renal angiosarcomas are highly aggressive neoplasms with a poor prognosis despite surgical treatment, chemotherapy, radiotherapy, or targeted therapy.
