title: Symptomatic hemorrhage associated with recurrent pilocytic astrocytoma with granulation tissue--case report.
abstract: A 51-year-old woman had been followed up for 10 years for recurrence of pilocytic astrocytoma 5 years after the initial treatment consisting of subtotal resection, chemotherapy, and radiation therapy. The patient presented with sudden onset of headache and vomiting. Computed tomography and T(2)*-weighted magnetic resonance imaging revealed hemorrhage in the tumor located in the right basal ganglia, thalamus, and hypothalamus. She underwent gross total resection of the lesion. Histological examination confirmed recurrent pilocytic astrocytoma with organizing hematoma and granulation tissue. Although neither symptomatic hemorrhage nor late benign recurrence is common, careful long-term follow up is necessary for patients with pilocytic astrocytoma.
