Intracranial Tumor
Intracranial tumors are the most common solid malignancy in pediatrics, with the majority found in the posterior fossa. In these patients, presenting symptoms and signs are frequently related to intracranial hypertension due to obstruction of cerebrospinal fluid flow. Specific cranial nerve palsies and ataxia may also be presenting signs, with or without intracranial hypertension. The anesthesia for surgical resection is nuanced by management of intracranial hypertension, the potential for hemodynamic instability, and postoperative complications resulting from damage to critical brainstem structures. This chapter discusses signs, symptoms, and differential diagnosis; tumor classification; anesthetic induction; and intraoperative and postoperative complications of surgery for a posterior fossa tumor.
