F18 FDG PET/CT findings in cat-scratch disease: a case report
Abstract
Cat-scratch disease is a bacterial infection caused by Bartonella Henselae which affects lymph nodes that drain the sites of inoculation. Axillary, cervical and inguinal lymph nodes are the most common regions being involved. The disease can be considered as an FDG-avid disease, given the granulomatous nature of the infection. We herein report F18 FDG PET/CT findings of a 49-year-old woman, who has abdominal lymphadenopathy revealed on ultrasonography (USG). PET/CT scan demonstrated bilateral axillary and abdominopelvic hypermetabolic enlarged lymph nodes with SUVmax value of 6.2 to 18.5. Moreover, a hypermetabolic hypodense lesion in the spleen with SUVmax value of 11.3 was detected. Excisional biopsy of the axillary lymph node performed. Based on clinical-histopathological findings and the history of being scratched by a cat recently, the patient was diagnosed with cat-scratch disease. In conclusion, cat-scratch disease represents a cause of false-positive results in oncological PET/CT scans. Furthermore, PET/CT may have a role in revealing the applicable biopsy area and showing the additional involvement sites. Keywords: Cat-Scratch Disease, PET-CT, Lymphadenopathy.
