Splenorenal Manifestations of Bartonella henselae Infection in a Pediatric Patient.

Rising T, Fulton N, Vasavada P - Case Rep Radiol (2016)

Bottom Line: A contrast-enhanced CT of the abdomen and pelvis was also obtained which showed hypoattenuating lesions in the spleen and bilateral kidneys.Bartonella henselae IgG and IgM titers were positive, consistent with an acute Bartonella henselae infection.The patient was discharged with a course of oral rifampin and trimethoprim-sulfamethoxazole, and all symptoms had resolved following two weeks of therapy.

ABSTRACT
Bartonella henselae is a bacterium which can cause a wide range of clinical manifestations, ranging from fever of unknown origin to a potentially fatal endocarditis. We report a case of Bartonella henselae infection in a pediatric-aged patient following a scratch from a kitten. The patient initially presented with a prolonged fever of unknown origin which was unresponsive to antibiotic treatment. The patient was hospitalized with worsening fevers and night sweat. Subsequent ultrasound imaging demonstrated multiple hypoechoic foci within the spleen. A contrast-enhanced CT of the abdomen and pelvis was also obtained which showed hypoattenuating lesions in the spleen and bilateral kidneys. Bartonella henselae IgG and IgM titers were positive, consistent with an acute Bartonella henselae infection. The patient was discharged with a course of oral rifampin and trimethoprim-sulfamethoxazole, and all symptoms had resolved following two weeks of therapy.

Longitudinal and transverse ultrasound images of the left upper quadrant demonstrate the spleen to be enlarged. Multiple small hypoechoic lesions (arrows) are seen within the spleen.

Mentions: On hospital day 2, a complete abdominal ultrasound demonstrated an echogenic liver which was slightly enlarged to 11 cm in the craniocaudal dimension at the right midclavicular line. The spleen was also enlarged to 7.8 cm and contained several small hypoechoic foci (Figures 1(a) and 1(b)). A contrast-enhanced CT was then recommended for further evaluation which showed small, poorly defined hypoattenuating lesions that were seen throughout the spleen suspicious for microabscesses (Figures 2(a) and 2(b)). Additionally, small, poorly defined hypoattenuating lesions were seen within the bilateral renal cortices, findings which were also compatible with microabscesses (Figures 3(a) and 3(b)).
