title: Infantile haemangiopericytoma: a rare congenital cervical tumour.
abstract: OBJECTIVE
  Infantile haemangiopericytoma is a rare childhood vascular tumour of borderline malignancy and unpredictable clinical course. It can present a diagnostic challenge due to indeterminate clinical, radiological and pathological features. This report presents the case of a large congenital haemangiopericytoma of the neck in a neonate, and discusses diagnosis, imaging, pathology and surgical management.
  
  
  METHODS
  A full-term neonate presented with a large posterior neck mass at birth. Pre-operative radiological appearances were suggestive of teratoma, but following surgical excision the diagnosis of infantile haemangiopericytoma was confirmed on histological analysis. There were no signs of recurrence at 12-month follow up.
  
  
  CONCLUSIONS
  Haemangiopericytoma can follow an aggressive course in adults, including local recurrence and metastasis. The infantile variant is rare but typically follows a distinct clinical course, and is associated with more benign behaviour compared with similar tumours in adults and children over one year. Congenital haemangiopericytoma can be effectively treated with surgery, without requiring adjuvant therapy.
