A 14-Year-old Healthy Boy with Splenic Abscess Due to Salmonella Enterica Serovar Senftenberg

Salmonella enterica serovar Senftenberg may very rarely cause splenic abscess, which can be diagnosed using gallium scintigraphy and drained. A 14-year-old boy admitted for stomachache, diarrhea and fever and diagnosed from his symptoms as having enteritis did not respond when treated with fosfomycin, meropenem, and clindamycin. A low-density splenic area seen in abdominal computed tomography on admission did not show contrast medium enhancement. Gallium scintigraphy on hospital day 10, however, showed abnormal splenic accumulation confirming the splenic abscess diagnosis, after which we punctured and drained the abscessout. S. Senftenberg was isolated from pus aspirated pus from the abscess, after which responded well to ceftriaxone and levofloxacin. Follow-up gallium scintigraphy on hospital day 24 showed that the abnormal splenic accumulation had disappeared, after which he has been followed up with abdominal ultrasonography and blood tests as an outpatient. He has experienced no relapse of splenic abscess.
