Abnormal Presentation of Bartonella henselae Encephalopathy in a Pediatric Patient.

Cat scratch disease (CSD) is a zoonotic infection caused by the transmission of gram-negative bacteria Bartonella henselae through a scratch or bite of a feline carrying B. henselae-infected fleas. CSD often presents clinically as a self-limited flu-like infection with painful regional lymphadenopathy appearing one to two weeks following initial transmission. However, a growing body of literature highlights abnormal presentations of Bartonella infections within the pediatric population. In this case report, we describe an atypical presentation of a B. henselae infection in an 11-year-old female with seizures, prolonged encephalopathy, agitation, and truncal instability. With an atypical presentation, a delay in diagnosis can result in potentially permanent organ damage, particularly as traditional empiric antibiotics fail to cover Bartonella infections. As such, proper treatment and complete resolution of symptoms require astute clinical recognition to make the correct diagnosis promptly.

Unconventional Obturator Artery Nutrient Branch: Image of an Anatomical Variation.

Variations in vascular anatomy are of great concern to surgeons, as proper identification of aberrant arteries can reduce the risk of iatrogenic injury and improve patient outcomes. Several studies have highlighted the irregular branching pattern of pelvic arteries, with a recent focus on the obturator artery (OA). The OA has an inconstant origin from the internal iliac artery, external iliac artery, or inferior epigastric artery. Within the pelvis, the OA can give off muscular branches and nutrient vessels to the ilium and pubis. Though occasionally described in text, few resources employ images of human donors that depict branches arising from the OAs. Out of the 34 hemisected pelves studied, we identified 1 individual with a substantial nutrient vessel branching unilaterally from the OA. Herein, we present the first image of this unconventional nutrient artery. This vessel should be highlighted given that its size and course make it particularly vulnerable during intrapelvic surgeries such as pelvic lymph node dissection or in procedures requiring arterial embolization of the OA.
