# Bilateral Renal Infarct in a Young Adult: Unveiling an Autoimmune Enigma

## TL;DR

A young man with sudden abdominal pain was found to have bilateral kidney damage linked to a rare heart condition and autoimmune factors.

## Contribution

This case highlights a rare connection between left ventricular non-compaction cardiomyopathy and bilateral renal infarction.

## Key findings

- CT scans confirmed bilateral renal infarcts in a young adult.
- The patient had positive antinuclear antibodies and left ventricular non-compaction cardiomyopathy.
- The case suggests a possible thromboembolic cause linked to the heart condition.

## Abstract

A man in his late 20s presented to the emergency department with sudden-onset abdominal pain. Urinalysis was significant for hematuria and slightly elevated creatinine. A computed tomography (CT) scan with IV contrast revealed bilateral renal infarcts, which was corroborated by a computed tomography angiogram (CTA). Further evaluation by an autoimmune panel demonstrated a positive antinuclear antibody, while echocardiography showed left ventricular non-compaction cardiomyopathy. The workup included consultations with multiple specialities and additional investigations to assess hypercoagulability, vasculitis, and infectious etiologies. Following supportive care, the patient was discharged in stable condition with a plan for outpatient follow-up and further workup, including screening of first-degree family members for left ventricular non-compaction and associated cardiovascular risks. Here we describe a report of a rare case of bilateral renal infarct of possible thromboembolic etiology due to an underlying rare genetic cardiovascular condition.
