# An Atypical Presentation of Bartter Syndrome Type 3 With Hypocalciuria and Opisthotonus Posture in a Preterm Infant

## TL;DR

A preterm infant showed rare symptoms of Bartter Syndrome Type 3, including low calcium in urine and a specific body posture, emphasizing the need for early diagnosis.

## Contribution

The paper presents a rare case of Bartter Syndrome Type 3 with hypocalciuria and opisthotonus in a preterm infant.

## Key findings

- The infant exhibited hypocalciuria and opisthotonus posture, atypical signs of Bartter Syndrome Type 3.
- Early recognition of these neuromuscular signs is crucial for timely genetic confirmation and management.

## Abstract

This case highlights an unusual presentation of Bartter Syndrome Type 3 marked by hypocalciuria and opisthotonus posture. Recognizing such atypical neuromuscular signs is essential for early diagnosis, genetic confirmation, and targeted management in pediatric patients with electrolyte imbalances.
