Objectives: After studying the article titled “Sonographic Evaluation and Diagnosis of Peritoneal Mesothelioma Resulting in Massive Intra-abdominal Ascites” you will be able to:
Describe the types of peritoneal mesothelioma.
Use appropriate sonographic techniques to document peritoneal mesothelioma.
Determine the extent of other abdominal pathology associated with peritoneal mesothelioma.
When sonography, computed tomography (CT), and fine-needle aspiration (FNA) biopsy are compared for the diagnosis of diffuse malignant peritoneal mesothelioma, gross pathology information is best provided by CT images gross pathology information is provided equally well by sonography or CT images none of the tests provide adequate diagnostic information sonography provides more information than CT regarding extent of disease
Ascites significant enough to cause abdominal distension is seen in approximately _____% of cases of diffuse malignant peritoneal mesothelioma. 50% 60% 70% 80%
Diffuse malignant peritoneal mesothelioma is seen in males in approximately _____% of cases. 55% 60% 65% 70%
The typical age group at risk for diffuse malignant peritoneal mesothelioma is adults older than 75 years adults between 45 and 50 years adults between 50 and 60 years adults between 65 and 70 years
Sonographic appearance of the tumors reported in this case study included ovoid hypoechoic masses free floating in the abdominal ascites small, brightly echogenic masses attached to the bowel wall long tubular structures primarily attached to the abdominal wall large encapsulated hypoechoic masses with no significant vascularity
The most common cellular subtype of diffuse malignant peritoneal mesothelioma is biphasic sarcomatoid epithelial Hurthle cell
The principal cause of morbidity related to diffuse malignant peritoneal mesothelioma is abdominal pressure increase and distension from tumor and fluid buildup heart failure kidney failure onset of diabetes secondary to pancreatic involvement
The cellular subtype of diffuse malignant peritoneal mesothelioma associated with the worst prognosis is biphasic sarcomatoid epithelial Hurthle cell
Important roles for sonography in the management of diffuse malignant peritoneal mesothelioma include all except
assessment of tumor fixation sites determination of the anatomic extent of the disease ultrasound-guided paracenteses for the buildup of ascites ultrasound-guided fine-needle aspiration biopsies
Best survival results for treatment for diffuse malignant peritoneal mesothelioma are usually obtained using cytoreductive surgery intraperitoneal chemotherapy radiation therapy a combination of (a) and (b)
