A case report of mediastinal extramedullary hematopoiesis: imaging, pathological and thoracoscopic biopsy correlation

To summarize the clinical features, imaging characteristics, and surgical diagnosis and treatment experience of mediastinal extramedullary hematopoiesis.

By summarizing and analyzing the case data and reviewing the literature, one case of posterior mediastinal extramedullary hematopoiesis on thoracoscopic biopsy in our department was summarized.

Posterior mediastinal extramedullary hematopoiesis is a response to failure of bone marrow erythropoiesis, which is relatively rare clinically, and diagnosis requires a combination of patient history and imaging, puncture biopsy or thoracoscopic excisional biopsy can provide a pathological diagnosis, and surgical complete resection is the main treatment modality.
