[Adult urachal cyst].

Area of Science:

• Urology
• Embryology
• Surgical Pathology

Background:

• Urachal cyst pathologies arise from the medial infraumbilical line, a rare occurrence in adults.
• Persistence of the urachus results from failed embryonic obliteration during the fourth gestational month.
• These lesions pose diagnostic challenges due to diverse clinical presentations.

Observation:

• A case of a urachal cyst in an adult woman is presented.
• The lesion was surgically excised.
• The case occurred at the Hospital Interamericano de Medicina Avanzada in Caguas, Puerto Rico.

Findings:

• Urachal cysts are rare adult pathologies.
• Clinical presentations can be varied, complicating diagnosis.
• Surgical excision is a treatment option.

Implications:

• Clinicians should consider urachal cysts in the differential diagnosis of infraumbilical cystic pathologies.
• Understanding the embryological origin aids in diagnosis and management.
• This case highlights the importance of considering rare urachal anomalies in adult medicine.
