Fibrous hamartoma of infancy at the wrist and the use of MRI in preoperative planning.

Fibrous hamartoma of infancy is an uncommon, self-limiting benign tumour that presents during the first 2 years of life, developing from subcutaneous fibrous tissue proliferation at almost any site. We describe the results of MRI of a lesion at the wrist. The scans enabled a planned surgical resection with the aim of preventing local recurrence without damaging important neurovascular structures.
