Before 1983 physicians diagnosed cat-scratch disease by its clinical manifestations and a positive Hanger-Rose skin test. Three out of four criteria, as outlined by Warwick, 1 were required for diagnosis. In 1983 Wear, et al.2 reported that they found gram-negative pleomorphic organisms using the Warthin-Starry stain on lymph nodes from patients with cat-scratch disease. The organism was then i...

BACKGROUND Cat-scratch disease (CSD) is mostly contracted by children and young adults. To our knowledge, CSD in elderly patients has never been characterized, and it may be underrecognized in this age group. METHODS The study population included all patients with CSD diagnosed at our reference laboratory during 1991-2002. Demographic, clinical, and laboratory data for patients with CSD aged ...

Cat scratch disease (CSD) caused by Bartonella henselae is the most common Bartonella infection worldwide. CSD usually presents as self-limiting lymphadenitis characterized by lymphadenopathy that occurs after contact with a cat and the symptoms resolve within 2 to 4 months. Serology testing is the cornerstone of diagnosis. However, it may require the use of clinical specimens for microbiologic...

Cat scratch disease (CSD) is a bacterial disease caused by Bartonella henselae and it is mainly characterized by self-limiting lymphadenopathy in the draining site of a cat scratch or bite. We report a patient with history of fever, swelling lymph nodes, vasculitic-like skin lesions, and positivity of Bartonella serology initially considered as expression of a disimmune disease.

Cat scratch disease is a non-epidemic infection caused by Gram negative bacillus Bartonella henselae. The most common course of the disease includes regional lymphadenitis and skin papule at the entrance site of the infection. We report a case of a female, 22 years of age, with cat scratch disease. Clinically we observed the typical skin papule at the entrance site of the infection with severe ...

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 are most common regions being involved. The can be considered as an FDG-avid disease, given granulomatous nature infection. We herein report F18 FDG PET/CT findings 49-year-old woman, who has abdominal lymphadenopathy revealed ...

A 3 year old girl with hepatosplenic cat scratch disease developed prolonged fever unresponsive to treatment with multiple antibiotics, including gentamicin, azithromycin, rifampin, and ciprofloxacin. Fever resolved with corticosteroid treatment.

An unusual case of primary meningo-encephalitis followed by partial complex seizure in a 9-year-old boy was found to be a symptom of cerebral Bartonella henselae infection or cat scratch disease. Despite one clinical relapse at 4 weeks post-presentation, he remained seizure free on carbamazepine for one year. Six months after stopping carbamazepine, however, he developed deja vu phenomena and a...

A 7-year-old boy was referred to us for evaluation of an enlarging neck mass. The results of his primary care physician's initial clinical examination suggested lymphadenopathy secondary to lymphadenitis, and the patient was treated over a 4-week period with two rounds of antibiotics. However, the mass did not resolve, and it subsequently became fluctuant. The patient was referred to our instit...

CT and MR imaging of the brain and gallium-67 scintigraphy showed an enhancing, gallium-avid mass in the left middle cranial fossa of a 10-year-old girl. Craniotomy revealed an inflammatory mass related to the left trigeminal nerve. The lesion contained rodlike bacteria, and serologic tests were positive for cat-scratch disease. Neurologic involvement in cat-scratch disease is uncommon, and the...
