Unicameral bone cyst with fracture

Case contributed by A.Prof Frank Gaillard

Well circumscribed, expansile, lucent lesion in the metaphysis and proximal diaphysis. Through the inferior aspect of the lesion a pathological fracture is noted, coursing obliquely downwards from medial to lateral. 

A prominent trabeculation through the upper part of the lesion on x-ray mimics a multiloculated lesion, however unilocularity is confirmed on CT. 

CT obtained sometimes later confirms that the lesion is well circumscribed and unilocular. 

Case Discussion

X-ray of the humerus of an 11 year old has features that are consistent with a unicameral bone cyst with pathological fracture.
