pleural biopsy
Tissue sampling procedure to obtain pleural specimens for histopathological diagnosis of pleural disease.
Full Definition
Pleural biopsy is a diagnostic procedure performed to obtain tissue samples from the pleural lining for histopathological examination when pleural effusion or pleural thickening is present. The procedure can be performed using various approaches including image-guided percutaneous biopsy, thoracoscopic biopsy, or blind pleural biopsy with an Abrams needle. In the context of suspected pleural malignancy, adequate tissue sampling is crucial for distinguishing between mesothelioma, metastatic disease, and benign pleural conditions. Thoracoscopic pleural biopsy is often preferred as it allows direct visualization and larger tissue samples.
Usage
Usage note: Specify the biopsy method when documented (percutaneous, thoracoscopic, etc.).
