CTICasesDisseminated Bartonella Henselae
Imaging findings
CT and MRI scans show multiple lytic bone lesions in the ribs and calvarium, associated with multiple low-attenuation lesions in the liver and spleen, in an immunocompromised patient. Biopsy confirmed disseminated Bartonella henselae (cat scratch disease).
Key takeaways
Disseminated Bartonella henselae is an important consideration in immunocompromised hosts. It can present with disseminated osteolytic bone lesions and hepatosplenic abscesses, mimicking metastatic malignancy, fungal infection, or tuberculosis, requiring tissue biopsy for diagnosis.
