Eosinophilic pleural effusion with Charcot-Leyden crystals

Area of Science:

• Thoracic Surgery
• Pulmonology
• Pathology

Background:

• Mediastinal tumors, particularly teratomas, can present with diverse clinical manifestations.
• Eosinophilic pleural effusions are uncommon and require thorough investigation for underlying causes.

Observation:

• A 17-year-old female patient presented with symptoms indicative of pleural effusion.
• Analysis of the pleural fluid revealed eosinophilia and the presence of Charcot-Leyden crystals.

Findings:

• Diagnostic imaging confirmed a benign cystic teratoma located in the anterior mediastinum.
• The teratoma was identified as the likely underlying cause of the eosinophilic pleural effusion.

Implications:

• This case underscores the importance of considering mediastinal masses in the differential diagnosis of unexplained eosinophilic pleural effusions.
• Early diagnosis and surgical management of benign cystic teratomas are crucial for favorable patient outcomes.
