Extralobar pulmonary sequestration of the left retroperitoneum

Extralobar pulmonary sequestration in children with abdominal pain: Four case reports

BACKGROUND

Extralobar pulmonary sequestration (ELS) with torsion is extremely rare, consequently, the diagnosis of ELS with torsion in children presents a challenge for clinicians. Herein, we report four cases of ELS with torsion that presented with abdominal pain, and further review the relevant literature to summarize the clinical features.

CASE SUMMARY

Four children presented to our department with abdominal pain. All underwent chest computed tomography, which revealed an intrathoracic soft tissue mass with pleural effusion. All four children underwent thoracoscopic resection of the identified pulmonary sequestration, and the vascular pedicle was clipped and excised. None of the patients experienced any postoperative complications.

CONCLUSION

Clinicians should consider the possibility of ELS with torsion in children presenting with abdominal pain as the chief complaint.

Intraabdominal pulmonary sequestration presenting with elevated urinary normetanephrine levels

Carrying a prenatal diagnosis of a left-sided intraabdominal mass, a term female newborn underwent postnatal imaging that confirmed a left suprarenal mass. Urinary normetanephrine levels were elevated. Given a preoperative diagnosis of neuroblastoma, the baby underwent an uneventful resection of the mass en bloc with the left adrenal gland. The pathologic examination returned pulmonary sequestration and a normal adrenal gland. Postoperative urinary catecholamines were normal. To the best of our knowledge, this is the first description of a newborn with an intraabdominal pulmonary sequestration presenting with elevated urinary catecholamines.

Prenatal sonographic detection of intra-abdominal extralobar pulmonary sequestration: report of three cases and literature review

Three cases of intra-abdominal extralobar pulmonary sequestration detected antenatally by ultrasound are reported. One case was associated with a large left diaphragmatic hernia. Sonographically, all the cases were found in the left supra-renal region presenting as a well-defined echogenic mass with cystic hypoechoic areas. The condition should be considered in the differential diagnosis of all antenatally detected upper abdominal echogenic masses, particularly when associated with a diaphragmatic hernia. Postnatal ultrasound-guided fine needle aspiration biopsy in one case yielded respiratory type epithelium and this procedure could provide a reasonably confident diagnosis of the lesion.
