Aneurysmal Bone Cysts of the Spine: Two Case Reports

Abstract

Aneurysmal bone cysts are rare entities which causes expansile and destructive bone lesions characterized by reactive proliferation of connective tissue. They usually grow rapidly with hypervascularity. In clinical practice they can be easily misdiagnosed due to the rare occurance and having no such typical findings as radiologically. Most cases have uncommon pain symptoms, but rarely, if fractures occur, neurological findings can be seen and the surgical treatment, if needed, could be difficult. We will discuss our evaluations to two cases that we experienced in our clinic in this report. Fig. 1. (A, B) Cyst extending to spinal canal with a press on me-dulla is observed on T2 images with non contrast MRI. The cyst is hyperechoic and prominent soft tissue extending is not seen. (C) On non contrast CT images, lytic-destructive expancil mass is observed on T corpus.
