Massive anterior mediastinal lipoma causing cardiac arrest in a middle-aged male: a case report and literature review.

Abstract

Lipoma is a common benign soft tissue tumor, but its size and location can lead to serious issues. We report a case of a 48 year-old male patient who experienced sudden cardiac arrest outside the hospital. After resuscitation and examination, we determined that this was due to a massive mediastinal lipoma compressing the lungs, leading to respiratory failure and pulmonary encephalopathy, ultimately resulting in cardiac arrest. This case serves as a reminder to promptly identify and manage chest lipomas to avoid compression and functional impairment of the respiratory system. Early evaluation and treatment of massive lipomas are crucial for preventing complications.
