Endoscopic Studies II: Thoracocentesis

246
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Summary

Spinal epidermoid cysts (EC) are rare. Prompt surgical removal of spinal EC causing paraparesis is crucial for optimal neurological recovery in patients.

Area of Science:

  • Neurosurgery
  • Neurology
  • Pathology

Background:

  • Spinal epidermoid cysts (EC) are exceptionally rare congenital, acquired, or iatrogenic lesions.
  • These intradural extramedullary tumors can cause significant neurological deficits.

Purpose of the Study:

  • To report a case of spinal epidermoid cyst presenting as progressive paraplegia.
  • To emphasize the importance of timely surgical intervention for optimizing neurological outcomes in spinal EC.

Main Methods:

  • A 62-year-old female with a 5-month history of progressive paraparesis underwent laminectomy and durotomy.
  • Gross total excision of the T7 level posterior compressive intradural extramedullary lesion was performed.

Main Results:

  • Histopathology confirmed the lesion as an epidermoid cyst.
  • Postoperatively, the patient experienced improved spasticity but only partial recovery of lower extremity motor function (3/5).

Conclusions:

  • Acute or subacute onset of paraparesis secondary to spinal EC necessitates prompt gross total cyst resection.
  • Early surgical management is critical for maximizing neurological recovery in patients with spinal epidermoid cysts.
