Ectopic hepatic tissue presented as a posterior mediastinal mass

Area of Science:

• Medicine
• Pathology
• Radiology

Background:

• Mediastinal masses can present with various respiratory symptoms.
• Ectopic tissues in unusual locations pose diagnostic challenges.

Observation:

• A pediatric patient presented with respiratory issues.
• Imaging revealed a right posterior mediastinal mass.
• Histological examination identified the mass as ectopic liver tissue.

Findings:

• The mediastinal mass was confirmed as histologically unremarkable ectopic hepatic tissue.
• This represents a rare case of intrathoracic liver.
• Literature review highlights the rarity and diagnostic considerations of ectopic liver.

Implications:

• Ectopic liver in the mediastinum is a rare congenital anomaly.
• Diagnosis requires careful histological assessment.
• Understanding these rare cases aids in clinical management and differential diagnosis.
