“…This theory is no longer retained for primitive ABC that present rearrangements of the USDP6 oncogene which is located on the chromosome 17, but it remains plausible in secondary ABCs which do not have translocation [2,3]. This lesion can develop in the entire skeleton but touch more frequently long bones (67%), then in the metaphysis of the long bones and in the vertebral column.…”

Introduction: Aneurysmal bone cyst (ABC) is benign osteolytic lesion expansile composed benign osteolytic expansile lesion composed of blood filled cystic cavities. It is mostly diagnosed in patients less than 20 years old. We report an aneurysmal cyst bone in the proximal phalanx of the fourth toe that was long considered as chondroma in X-rays finding. Case Report: We report the case of a 24-year-old military male, with history of ankle traumatism since six months from falling from the stairs. He presented to the Radiology Department of the military hospital of Rabat where anteroposterior and lateral radiographs of the left foot were realized. They showed an osteolytic bone lesion in the proximal phalanx of the fourth toe, expansile, without periosteal reaction or calcifications, first diagnosed as chondroma and treated symptomatically by nonsteroidal anti-inflammatory drugs. The patient was referred a second time to our department for nonresolving dull aching pain in the left foot since the trauma. On physical examination, there was no palpable mass, no cutaneous sign, no motor deficit, and the local temperature was normal. Magnetic resonance imaging (MRI) was performed for further characterization of the lesion. It showed a cystic lesion that present with hypointense signal on the T1 weighted sequences and hyperintense signal on T2 weighted sequences.
