Rationale:
Ectopic bronchogenic cysts (EBCs) are rare congenital lesions, mostly located in the mediastinum. They are extremely rare in the abdomen, particularly near the spleen.
Patient Concerns:
A 48-year-old Chinese female, who was asymptomatic and undergoing a routine health examination, was incidentally found to have a low-density soft tissue mass near the spleen. Preoperative considerations included a mucinous tumor, a gastrointestinal stromal tumor, or malignant tumors such as gastric cancer.
Diagnoses:
A contrast-enhanced computed tomography scan showed a 2.6 cm soft tissue mass between the stomach and spleen. Gastroscopy revealed no significant abnormalities, and laboratory tests were normal. Laparoscopic exploration identified the mass in the splenic fossa, and histopathological examination confirmed it as an ectopic bronchogenic cyst.
Interventions:
The patient underwent laparoscopic resection of the mass, involving dissection of adhesions and separation from the spleen.
Outcomes:
The patient recovered uneventfully postoperatively and was discharged after six days. Follow-up computed tomography at four months showed no recurrence, and the patient remained asymptomatic.
Lessons:
Recognizing ectopic bronchogenic cysts in rare abdominal locations, like the spleen, is essential for proper diagnosis and treatment. Early intervention for suspected malignant tumors, especially with minimally invasive laparoscopic surgery, is key to effective management and can make a significant difference in patient outcomes.
