title: Cerebellar hemangioblastoma associated with diffuse neonatal hemangiomatosis in an infant.
abstract: BACKGROUND
  Hemangioblastomas (HBLs) comprise approximately 2% of all primary central nervous system (CNS) tumors. Although histological features of this rare tumor are generally benign, its outcome is often unfavorable due to high risk of recurrence and multifocal localization. HBLs can be detected as sporadic or associated with Von Hippel-Lindau disease. Diffuse neonatal hemangiomatosis (DNH) presents with multiple, progressive, rapidly growing cutaneous hemangiomas associated with widespread visceral hemangiomas in the liver, lungs, gastrointestinal tract, brain, and meninges. DNH with predominant CNS involvement is rarely reported. Herein, we present a neonatal case of cerebellar HBL associated with DNH.
  
  
  METHODS
  A 5-day-old male baby was referred with complaints of multiple cutaneous lesions. Purple papules were noted on the trunk, extremities, and the head. Thoracic magnetic resonance imaging demonstrated multiple hyperintense lesions on the chest wall and apex of the right lung. On MRI, a 3×2-cm mass lesion in the right cerebellar hemisphere was detected. Total resection of the mass and ventriculoperitoneal shunting was performed. Histopathologic examination confirmed the diagnosis of HBL. Steroid therapy was administered for disseminated hemangiomatosis, and the lesions showed regression; the patient showed good clinical recovery. The parents refused further treatment, and he was out of our control when he was 9 months old.
  
  
  CONCLUSIONS
  According to our knowledge, the presented newborn is the second case of cerebellar HBL associated with diffuse skin and visceral hemangiomas in the English medical literature. Clinicians must be vigilant about the predictive value of visceral and/or cutaneous hemangioma for an associated intracranial HBL.
