Objective:

To Present case reports and a brief review of aneurysmal bone cysts secondary to lymphomas.

Material and Methods:

Images from the archive of the Radiology and Diagnostic imaging department were obtained from patients seen at the Fundación Oftalmológica de Santander – Carlos Ardila Lülle Clínic (FOSCAL) being diagnosed of an aneurysmal bone cyst secondary to lymphoma.

Results:

Two clinical cases were reported on patients who developed a cystic bone tumor corresponding to an aneurysmatic bone cyst secondary to lymphoma.

Conclusions:

The aneurysmatic bone cyst is a rare tumor that constitutes only 1-2% of bone tumors. It mainly affects the metaphysis of long bones and occurs predominantly in young adult patients who are in the second decade of life. Despite the existence of multiple theories about its origin, there is still no clear etiology. The diagnostic approach is radiological, specifically with magnetic resonance images however, the diagnostic must be confirmed with histopathological studies.
