Computed tomography demonstration of pancreatic microcystic adenoma
Abstract:
Microcystic adenoma is an uncommon pancreatic neoplasm that is generally thought to be a benign tumor. Herein, we review the literature related to microcystic adenomas and discuss the use of computed tomography in the differential diagnosis of the tumor. The controversy in pathology regarding the presence or absence of a potential for malignant degeneration in microcystic adenomas is presented along with the therapeutic controversy regarding the necessity for total surgical excision. Two new cases of pathologically proven microcystic adenoma of the pancreas are reported. In one case there was evidence of metastasis by computed tomography, sonography, and scintigraphy.
Insights
Microcystic adenomas are rare pancreatic tumors, usually benign. However, one case showed metastasis, raising questions about their potential for malignancy and treatment necessity.
Area of Science:
- Gastroenterology and Hepatology
- Surgical Oncology
- Diagnostic Imaging
Background:
- Microcystic adenoma is an uncommon pancreatic neoplasm.
- It is generally considered a benign tumor.
Observation:
- This review discusses computed tomography (CT) in the differential diagnosis of microcystic adenomas.
- Pathological and therapeutic controversies regarding malignant potential and surgical excision are presented.
- Two new cases of pathologically proven microcystic adenoma are reported.
Findings:
- One reported case demonstrated evidence of metastasis via CT, sonography, and scintigraphy.
- This finding challenges the notion of universal benignity for microcystic adenomas.
Implications:
- The potential for malignant degeneration in microcystic adenomas requires further investigation.
- Diagnostic imaging plays a crucial role in evaluating these pancreatic neoplasms.
- Treatment strategies may need re-evaluation based on potential for metastasis.
