A pleural-based lesion is an abnormal growth or mass located on or near the pleura, which is the double-layered membrane surrounding the lungs. These lesions can arise from various conditions, including infections, tumors, or inflammatory processes. Common types include pleural effusions, mesotheliomas, and metastatic cancers. Diagnosis usually involves imaging studies and sometimes biopsy to determine the underlying cause and appropriate treatment.
Pleural-based opacity refers to opacity seen in X-rays along the pleural surface. The opacity or silhouettes can mean many things like signs of injuries, possible thickening, or indications of disease.
Location and size
what is pleural thickening
Lesion excisions are coded based on their size vs the number of lesions excised. All lesion sizes of the same area are added together & coded based on the size. 11643 - excision, malignant lesion including margins, face, ears, eyelids, nose, lips; excised 2.1 cm - 3.0 cm
pleural membrane
pleural rub
the diagnosis of cutaneous disease often is based on the appearance of a specific type of lesion or group of lesions.
Pleural cavity is the potential space. There is no gap between the outer and the inner pleura. There is very little fluid in the pleural cavity. You have negative pressure in the pleural cavity.
The lungs
doctors will determine whether or not a particular lesion or lesions are cancerous based on observation and the results of an excisional or punch biopsy, in which a tissue sample is excised for microscopic analysis.
Proximal lesion
The pleural cavity is located in between the visceral and parietal of the lungs.
