A few patients with CSD have been described with osteolytic lesions but not true osteomyelitis. These patients do not have a fever or leukocytosis.

Back pain as the presenting symptom has been reported. In one case report, CT scanning revealed a soft-tissue mass dorsal to the processi transversa L1-2, and MRI revealed a contrast-enhancing paraspinal mass with infiltration of the erector spinae consistent with inflammation. [54] B henselae immunoglobulin (Ig)M antibody findings were positive. The patient spontaneously recovered after about 1 month.
