Extralobar pulmonary sequestration as an intraabdominal tumour.

Area of Science:

• Medical Diagnostics
• Surgical Oncology
• Congenital Anomalies

Background:

• Pulmonary sequestration is a rare congenital lung anomaly with abnormal tracheobronchial communication and systemic blood supply.
• Extralobar sequestration, lacking tracheobronchial connection, often presents asymptomatically or with non-infectious complications.
• Computed tomography (CT) is crucial for diagnosing pulmonary sequestration by visualizing feeding vessels.

Purpose of the Study:

• To report a rare case of pulmonary sequestration diagnosed incidentally in an adult patient.
• To emphasize the diagnostic and management considerations for extralobar pulmonary sequestration in older individuals.

Main Methods:

• An incidental retroperitoneal tumor was detected via abdominal ultrasound in a 68-year-old patient with nephropathy.
• CT scan confirmed the tumor, leading to surgical excision due to suspected neurogenic origin.
• Postoperative monitoring included oxygen therapy for hypoxemia.

Main Results:

• Surgical resection of the retroperitoneal tumor was performed.
• The patient experienced an uncomplicated postoperative recovery and was discharged on day 5.
• The case highlights an unusual presentation of pulmonary sequestration in an adult.

Conclusions:

• Pulmonary sequestration is an exceptionally rare diagnosis in adult patients.
• Incidental findings on imaging can lead to the diagnosis of rare congenital anomalies.
• Surgical resection remains the primary treatment for pulmonary sequestration to prevent complications.
