# An Uncommon Presentation of Renal Angiomyolipoma: A Case Report

## TL;DR

A 77-year-old woman with a rare kidney tumor and a lung condition was found to have tuberous sclerosis, and her high blood pressure improved after treatment.

## Contribution

This case report highlights the rare presentation of renal angiomyolipoma as a cause of secondary hypertension in the context of tuberous sclerosis.

## Key findings

- Renal angiomyolipoma was identified as a cause of secondary hypertension in a patient with tuberous sclerosis.
- Embolization of the renal AML led to improved blood pressure control and symptom resolution.
- The patient also had lymphangioleiomyomatosis, a known association with tuberous sclerosis.

## Abstract

Renal angiomyolipoma (AML) is a rare benign tumor of the kidney that can occur as a sporadic lesion or a part of tuberous sclerosis. A 77-year-old female patient with a history of hypertension, hyperlipidemia, and an unclear history of left nephrectomy in 1999 presented with progressive shortness of breath and palpitations. Her vital signs showed elevated blood pressure, and the examination was benign and non-focal. A work-up showed multiple lesions in her lungs and right kidney, representing lymphangioleiomyomatosis. The patient was diagnosed with tuberous sclerosis and was followed up by pulmonology and nephrology. She underwent embolization of the renal AML, after which her blood pressure (BP) was more controlled, and she reported feeling well and symptom-free. Renal AML, as a part of tuberous sclerosis, is a rare cause of secondary hypertension. Embolization of AML is effective in controlling BP.
