Summary
Intrathoracic extramedullary hematopoiesis, a rare condition, can cause massive chylothorax even without hematologic disorders. This case highlights successful treatment using talc pleurodesis and low-dose radiotherapy.
Area of Science:
- Medicine
- Hematology
- Thoracic Surgery
Background:
- Intrathoracic extramedullary hematopoiesis (IEH) is a rare condition, typically associated with hematologic disorders.
- IEH commonly occurs in the paravertebral sulci and is usually asymptomatic.
- Pleural involvement of IEH is exceptionally rare.
Observation:
- A 54-year-old male patient presented with massive bilateral chylothorax.
- The patient had no history of hematologic disorders or pleural malignancy.
- The chylothorax was attributed to primary pleural extramedullary hematopoiesis.
Findings:
- This case represents a rare instance of IEH primarily affecting the pleura.
- The patient experienced a massive bilateral chylothorax as a direct consequence of pleural IEH.
- Successful management was achieved through a combination of therapeutic interventions.
Implications:
- This case expands the understanding of IEH presentation and its potential complications.
- It suggests that IEH should be considered in the differential diagnosis of chylothorax, even in patients without hematologic conditions.
- The successful treatment highlights the efficacy of video-assisted thoracoscopic talc pleurodesis and low-dose radiotherapy for this rare condition.
