# Isolated mediastinal lymphangioma in a child: A rare case report

## TL;DR

A rare case of a mediastinal lymphangioma in a young child is reported, emphasizing the importance of accurate diagnosis using multiple imaging techniques.

## Contribution

This case report provides insights into the radiological features of isolated mediastinal lymphangioma in children.

## Key findings

- Multimodal imaging confirmed a diagnosis of mediastinal cystic lymphangioma with internal haemorrhage.
- Surgical excision and histopathology confirmed the diagnosis of cystic lymphangioma.
- Accurate diagnosis helps avoid unnecessary interventions and complications.

## Abstract

The mediastinum is an unusual location for cystic lymphangiomas. An 18-month-old male presented with acute fever, dry intermittent cough and respiratory distress. Chest radiography, ultrasonography, contrast-enhanced CT and MRI suggested a diagnosis of mediastinal cystic lymphangioma with internal haemorrhage. Surgical excision of the lesion and histopathological examination confirmed cystic lymphangioma.

This case highlights the multimodal radiological features of isolated mediastinal cystic lymphangioma for accurate diagnosis and improved management, to avoid unnecessary interventions and complications.
