Infantile Tumoral Calcinosis of the Cervical Spine: A Case Report.

Tumoral calcinosis (TC) is an exceedingly rare disease, significantly so when located in the spine. Here, we present a 4-month-old patient with decreased head control and range of motion of the neck for several weeks. CT and MRI demonstrated a calcified mass in the retropharyngeal area and surrounding C1/C2, and TC was suspected. The patient underwent surgical biopsy and aspiration, which confirmed TC. The purpose of this case report is to document a rare disease, significantly so when taking into account both the location of the lesion and the patient's age, and to detail the treatment and response.
