title: Chondromyxoid Fibroma of Two Cervical Vertebrae with Involvement of Surrounding Soft Tissue: Radiologic Diagnostic Dilemma.
abstract: Chondromyxoid fibroma is a rare benign cartilaginous neoplasm that mostly affects the metaphyseal region of the long bones. The tibia, small tubular bones of the foot, the distal femur and pelvis are common locations, but involvement of the vertebral bones, especially the cervical vertebra, is very rare. Radiographic features show typical characteristics and this tumor often presents as a lobulated, eccentric radiolucent lesion with no periosteal reaction. In addition, geographic bone destruction is seen in all cases. We present an adult female with a one-year history of neck pain, and ultrasound findings that suggest a right paravertebral muscular lesion due to inflammatory or neoplastic origins. The histopathological studies confirmed that the biopsied specimen was a chondromyxoid fibroma of the cervical vertebrae laminae and spinous processes (C3 and C4) with abutting soft tissue. Despite the unusual location and soft tissue presentation, a chondromyxoid fibroma should be considered in the differential diagnosis of a cervical bone lesion.
