Intramural gastric pseudocyst: A case report and a comprehensive literature review
MetadataShow full item record
Rationale: Intramural pseudocyst, although first reported several decades ago, is a rare entity. Scientific knowledge regarding its clinical management is sparse.
Patient concerns: We present three cases to show the diverse clinical patterns of patients diagnosed with an intramural gastric pseudocyst.
Diagnosis: A final diagnosis should rest on proper evaluation by cross sectional imaging, including computer tomography and magnetic resonance imaging. Endoscopic ultrasound adds to the work-up.
Interventions: Previously, identified “lesions of the gastric wall” were not well recognized as an intramural pseudocyst, and treatments including resectional surgery were employed. Contemporary proper diagnostics should provide support to a less aggressive treatment approach.
Outcomes: While an indolent natural history without any clinical symptoms or discomfort could be expected in most cases, individual clinical evaluation should be applied.
Lessons: A heterogeneous information pattern from the limited number of cases in the literature makes it difficult to draw any firm conclusions. Attention to this rare condition should be increased to help clinicians arrive at a correct diagnosis and possibly prevent some patients from being over treated or from the use of unnecessary surgery.
