Answer

CT imaging is 100% specific for the diagnosis

Answer

Blood tests reliably confirm mesothelioma in early stages

Question 2

Superior vena cava (SVC) syndrome developing in a mesothelioma patient most likely results from:

Accepted Answer

Direct tumor compression or invasion of the SVC or mediastinum

Answer

Metastatic spread to the contralateral lung

Answer

Pleural effusion compressing the heart

Answer

Paraneoplastic coagulopathy causing venous thrombosis

Question 3

What is the significance of finger clubbing in a patient being evaluated for mesothelioma?

Accepted Answer

It suggests underlying chronic hypoxia and pulmonary disease, raising suspicion for advanced thoracic malignancy

Answer

It is pathognomonic for mesothelioma

Answer

It rules out mesothelioma and suggests primary lung cancer instead

Answer

It indicates successful response to treatment

Question 4

In peritoneal mesothelioma, which symptom pattern best helps clinicians distinguish it from ovarian cancer in women?

Accepted Answer

Peritoneal mesothelioma is associated with a history of asbestos exposure and diffuse peritoneal thickening without an ovarian mass

Answer

Peritoneal mesothelioma exclusively causes right-sided pain

Question 5

Dysphagia developing in a patient with pleural mesothelioma most likely indicates:

Accepted Answer

Answer

A co-existing esophageal primary tumor

Answer

Answer

Aspiration pneumonia secondary to pleural effusion

Question 6

Which paraneoplastic syndrome is occasionally reported in association with mesothelioma and can complicate clinical evaluation?

Accepted Answer

Hypercalcemia of malignancy due to PTHrP secretion

Answer

Syndrome of inappropriate antidiuretic hormone secretion (SIADH)

Answer

Autoimmune hemolytic anemia

Answer

Cushing syndrome from ACTH secretion

Question 7
