Insights

Symptomatic subependymomas in the lateral ventricle and septum pellucidum were surgically cured in two cases. Imaging revealed calcified masses with hemorrhage, and histology confirmed subependymoma, highlighting characteristic features.

Area of Science:

  • Neurosurgery
  • Neuroradiology
  • Neuropathology

Background:

  • Subependymomas are rare, slow-growing glial tumors typically found in the ventricles.
  • Symptomatic presentations often necessitate surgical intervention for definitive diagnosis and treatment.
  • Understanding the imaging characteristics and biological behavior is crucial for management.

Observation:

  • Two cases of symptomatic subependymomas in the lateral ventricle and septum pellucidum are presented.
  • Magnetic resonance imaging (MRI) and computed tomography (CT) demonstrated calcified lesions with evidence of intratumoral hemorrhage.
  • Cerebral angiography indicated hypovascularity of the tumors.

Findings:

  • Histopathological examination confirmed the diagnosis of subependymoma in both cases.
  • Surgical resection resulted in a complete cure for both symptomatic patients.
  • The study reviews literature on surgically treated subependymomas, discussing their unique biological traits.

Implications:

  • This case series emphasizes the importance of advanced imaging techniques like MRI in diagnosing subependymomas.
  • Surgical management is effective for symptomatic subependymomas, leading to favorable outcomes.
  • Further understanding of subependymoma biology may refine treatment strategies and improve patient care.
