The Following CT-Scan Would Suggest What?
Malignant Mesothelioma
Pleural thickening and nodularity on the right are common findings of malignant mesothelioma. Malignant mesothelioma is associated with asbestosis exposure in 77% of cases. Asbestosis exposure has been demonstrated in the following industries: ship building, construction, ceramics, paper mill, auto parts, railroad and insulation.
Pleural mesothelioma is often unilateral, with a nearly twofold predilection for the right pleura. Keep in mind basic anatomy; the right main stem bronchus is at less of an angle than the left allowing foreign material to reach lung tissue more easily.
Although the CT-Scan is not diagnostic, it is highly suggestive. A pleural biopsy of these areas is the diagnostic test of choice. Currently, treatment is a tri-modality approach starting with surgical resection of the tumor if possible, followed by radiation therapy to the region, and finally chemotherapy. The prognosis of the disease is poor with most patients living only 8-14 months even with treatment.
