Monoclonal gammopathy reflects a serological disorder suggesting a plasma cell dyscrasia or a B-cell abnormality. However, it may occasionally be encountered as a transient manifestation in the course of several diseases including infections. This is the first reported case of a transient monoclonal gammopathy IgG lambda light chain associated with a Staphylococcus aureus infection that was complicated with renal abscess and vertebral spondylodiscitis in a previously healthy 68-year-old male. We observed a complete resolution of the gammopathy within three months of medical treatment before the entire restoration of all clinical and laboratory findings. Many invasive and cost-intensive diagnostic procedures had preceded the exclusion of a malignancy. The clinical significance and the exact pathogenesis of transient monoclonality are poorly understood and remain a matter of speculation.
