A rare presentation of primary lymphoma of bone with aneurysmal bone cyst-like changes

Primary lymphoma of bone occurs rarely in children with variable imaging findings ranging from a lytic lesion to an aggressive permeative lesion. We detail a case report with review of literature of a 14-year-old boy with a rare presentation of primary lymphoma of bone with aneurysmal bone cyst-like changes. The lesion was surgically excised as management for aneurysmal bone cyst but histopathological examination of the excised tissue revealed a non-Hodgkin's type of lymphoma. This unique type of aneurysmal bone cyst-like presentation has not been well characterised until now in the imaging spectrum of primary lymphoma of bone. Clinicians need to be aware of this uncommon presentation for early intervention and appropriate management of this malignancy in children.
