title: Infantile tumoral calcinosis of the cervical spine presenting as torticollis.
abstract: The computed tomography (CT) and MRI findings of infantile tumoral calcinosis and the utility of image-guided biopsy are demonstrated. A 5-month old presented with torticollis and a calcified cervical spinal mass. The radiologic appearance suggested a malignant neoplasm, prompting CT-guided biopsy, which diagnosed tumoral calcinosis. We hope to increase awareness of this entity and describe image-guided biopsy as a way to avoid morbidity associated with open biopsy.
