Retroperitoneal bronchogenic cyst presenting as an adrenal mass

Area of Science:

• Thoracic Surgery
• Surgical Pathology
• Gastrointestinal Surgery

Background:

• Bronchogenic cysts are congenital anomalies typically found in the mediastinum.
• Subdiaphragmatic and retroperitoneal locations are exceedingly rare.
• Literature review confirms the rarity of retroperitoneal bronchogenic cysts.

Observation:

• A unique case of a retroperitoneal bronchogenic cyst presenting as a symptomatic adrenal mass is described.
• The cyst mimicked an adrenal tumor, highlighting diagnostic challenges.
• This presentation is distinct from previously reported retroperitoneal cases.

Findings:

• This report adds a fourth case to the literature of retroperitoneal bronchogenic cysts.
• The adrenal mass presentation underscores the diverse clinical manifestations of these rare cysts.
• Analysis of subdiaphragmatic bronchogenic cyst cases provides further context.

Implications:

• Increased awareness of rare ectopic presentations of bronchogenic cysts is warranted.
• Diagnostic imaging and surgical planning must consider these unusual locations.
• This case contributes to the understanding of rare congenital thoracic malformations extending into the retroperitoneum.
