Introduction Renal angiomyolipoma is considered a benign mesenchymal tumor composed of fat, smooth muscle, and blood vessels. It represents 1–3% of solid renal tumors. Despite this tumor’s benignity, it can be aggressive with a locoregional extension. Case report A 41-year-old north African caucasian woman consulted with chief complaints of right lower back pain with no hematuria and no urinal sign. Thoracic-abdominopelvic contrast-enhanced computed tomography showed a right inferior polar heterogeneous renal mass complicated with venous thrombus ascending to the right atrium level. The patient underwent radical nephrectomy under extracorporeal circulation and direct supervision of the fatty thrombus at the right atrium level. The postoperative period was uneventful. The final histologic examination was concordant with renal angiomyolipoma. Conclusion Renal angiomyolipoma is the most common benign kidney tumor. Despite its benignity, it can be associated with lethal complications such as hemorrhage, and it can also show signs of local extension mimicking malignant tumors. The cornerstone of the treatment remains surgery.

Angiomyolipoma (AML) complicated with tumour thrombus extending to the confluence of inferior vena cava (IVC) with right atrium is rarely observed. We report a female AML patient admitted to our centre on January 21, 2020, with complication of tumour thrombus extending to the confluence of IVC with right atrium and had no sign of difficult breathing. She underwent whole-abdominal enhanced CT for abdominal pain and was diagnosed with a possible renal AML with tumour thrombus. Open radical nephrectomy and thrombectomy of vena cava were performed. Intraoperative transoesophageal echocardiography indicated that the tumour thrombus has reached the confluence of IVC with right atrium. The operation took 255 min with an intraoperative haemorrhage of 800mL. The patient was discharged 7 days after surgery. Pathology revealed lipoma-like AML. Immunohistochemistry showed vimentin (+), EMA (−), HMB45 (+), S-100 (−), SMA (+), TFE-3 (−), melan A (+). After 2 years of follow-up, we found that the patient showed full recovery and had no recurrence. Therefore, lipoma-like AML should also be followed closely for recurrence and metastasis. When AML involves IVC tumour thrombus, open thrombectomy and radical nephrectomy are safe and effective methods.

O angiomiolipoma (AML) é o tumor renal benigno mais comum e trata-se de uma neoplasia de formação mesenquimal, composta por vasos sanguíneos, músculo liso e tecido adiposo 1–10. Apresenta uma grande associação com Esclerose Tuberosa (TSC) e Linfangioleiomiomatose. Neste trabalho relatamos o caso de uma paciente de 28 anos, do sexo feminino, com diagnostico prévio de TSC que deu entrada no serviço de emergência com um quadro de dor abdominal e sinais de choque hipovolêmico. O diagnóstico realizado com auxílio da tomografia computadorizada com contraste foi de ruptura de AML, caracterizando o quadro como um caso de Síndrome de Wunderlich, com necessidade de abordagem cirúrgica. A paciente evoluiu de maneira satisfatória, tendo alta após 7 dias de internamento. Em retorno ambulatorial, o anatomopatológico confirmou a suspeita diagnóstica de AML, sem sinais de malignidade.
