Two-stage approach in the management of thoracic neuroenteric cyst with spinal extension: thoracoscopic excision following dorsal laminectomy

BACKGROUND

Neuroenteric cysts (NC) are rare pathologies and localized generally in posterior mediastinum or abdomen where they may extend to spinal canal through a vertebral defect. Isolated spinal lesions require dorsal/ventral laminectomy and thoracic ones thoracotomy or thoracoscopy. Posterolateral approach via thoracotomy is generally performed for lesions with both thoracic and spinal components. Minimal invasive excision of a thoracic NC with spinal extension in an infant is presented herein.

CASE REPORT

A term female newborn with an antenatal (26th week) diagnosis of congenital diaphragmatic hernia (CDH) was admitted. On physical examination, she was normal except mild dyspnea and CDH were excluded on radiogram. Left parenchymal opacity necessitated thorax tomography that revealed lobulated cystic lesion (6 × 3.5 × 4.5 cm) in posterior mediastinum. MRI showed intraspinal extension of the lesion through a hemivertebrae (6th). Two-stage procedure was planned for suspected neuroenteric cyst. First, intraspinal component was excised with dorsal laminectomy and the connection was closed. Then, the thoracic component was excised thoracoscopically. Histopathological evaluation confirmed the diagnosis. Total parenteral nutrition and high dose somatostatin analog was needed due to transient left chylothorax on postoperative course. She was well and symptom-free in postoperative period.

CONCLUSION

Neuroenteric cysts may lead to misdiagnoses in antenatal period. MRI is critical to show spinal and vertebral pathologies in suspected cases. Thoracoscopy may safely be performed for thoracic lesions with spinal extension in two-stage approach following closure of the connection and excision of the spinal component.

Miscellaneous causes of pediatric chest pain

This article describes some of the miscellaneous etiologies of pediatric chest pain that are important to recognize early and diagnose. Up to 45% of pediatric chest pain cases may elude definitive diagnosis. Serious morbidity or mortality is infrequent. Accurate diagnosis of more obscure causes may help to avoid unnecessary emergency department evaluation and cardiology referral, while also alleviating the concern and stress families and patients experience when dealing with chest pain.

Open approaches to posterior mediastinal tumor in adults

Thoracic surgeons must be familiar with available surgical approaches for posterior mediastinal tumors in order to choose the approach that will contribute to better prognosis and patient quality of life. An open surgical approach should be decided on based on the tumor size, location, and pathology. This article discusses the indications for the open approach in adults and outlines the surgical procedure.
