The usual presentation of cat-scratch disease (CSD) is a subacute regional lymphadenitis following cutaneous inoculation. We present the case of a 10-yr-old white female with a 4-wk history of abdominal pain and fever, without associated lymphadenopathy. A 67Ga scintigram showed inhomogenous uptake by the liver. An abdominal computed tomographic (CT) scan revealed multiple low density lesions in the liver and the spleen, that were confirmed at laparotomy. Stellate microabscesses were seen on a wedge biopsy of the liver and a CSD antigen skin test was positive. CSD should be considered in the differential diagnosis of liver lesions, even in the absence of lymphadenopathy. This case emphasizes the importance of inhomogeneous 67Ga uptake by the liver.

A 12-year-old girl with a 2-month history of fever and abdominal pain was admitted to our hospital. Ultrasound and CT scans of the abdomen showed multiple hypoechoic lesions of liver and spleen. Screening for zoonosis revealed high positive titers to Bartonella henselae. T-cell deficiency was demonstrated and remained almost unchanged during a follow-up of 11 months. A review of the literature shows that disseminated visceral affection is a rare presentation of cat scratch disease (CSD) in childhood and adolescence. Further immunological investigations are needed in more patients with CSD to confirm whether an altered immunological state may be responsible for the atypical visceral manifestation of CSD.

We reviewed 19 cases of hepatosplenic cat-scratch disease at Texas Children's Hospital (Houston). The range of the patients' ages was 2 years 4 months to 11 years 8 months. The chief complaint was fever for all patients. The duration of fever before diagnosis was 7 to 56 days (mean, 22 days). Abdominal pain was present in 13 patients (68%). Thirteen children were treated with rifampin alone, and three received rifampin therapy plus gentamicin or trimethoprim-sulfamethoxazole. Once rifampin therapy was initiated alone or in combination, improvement was noted within 1 to 5 days (mean, 2.6 days) for patients who had had prolonged fever the duration of which before rifampin therapy averaged 3 weeks. The most common dosage and duration for our patients were 20 mg/[kg x d] every 12 hours and 14 days, respectively. Rifampin should be considered in the initial antimicrobial treatment of hepatosplenic cat-scratch disease.

We report a case involving a 15-year-old girl with atypical, clinically unsuspected cat scratch disease (CSD) presenting as isolated posterior pancreatic duodenal lymphadenitis, fever, and abdominal pain. The serological, abdominal ultrasonographic, and CT findings, as well as clinical and epidemiological data, indicate that B. henselae was likely an etiologic agent of CSD in our patient.

Cat-scratch disease is caused by a Gram-negative bacillus known as Bartonella henselae. This disease is usually benign and causes regional adenitis that does not require treatment. However, some patients develop more serious atypical forms of the disease including prolonged systemic illness with hepatic and splenic abscesses.A 14-year-old girl was admitted to hospital with a 12-day history of persistent high fever and abdominal pain. Ultrasonography and computerized tomography of the abdomen revealed splenic abscesses. These findings, together with an antecedent of cat exposure, led to the suspicion of cat-scratch disease, which was confirmed by serology. The girl was treated with intramuscular ceftriaxone and clinical evolution was favorable. Splenic cat-scratch disease is infrequent. Cat-scratch disease sometimes presents as fever of unknown origin and consequently this disease should be considered in the differential diagnosis of prolonged fever. Although evolution is usually favorable, antibiotic therapy is recommended in systemic manifestations of cat-scratch disease.

Systemic cat scratch disease (CSD) is often associated with prolonged fever and microabscesses in the liver and/or spleen. We report a case of systemic CSD with hepatic, splenic and renal involvement in an aboriginal child in Taiwan. A previously healthy 9-year-old girl had an intermittent fever for about 17 days, and complained of abdominal pain, headache and weight loss. Abdominal computed tomography showed multiple tiny hypodense nodular lesions in the spleen and both kidneys. Laparotomy revealed multiple soft, whitish-tan lesions on the surface of the liver and spleen. Histopathologic examination of a biopsy specimen of the spleen showed necrotizing granulomatous inflammation with central necrosis surrounded by epithelioid cells and occasional Langhans' giant cells, strongly suggestive of Bartonella henselae infection. History revealed close contact with a cat. B. henselae DNA was detected by polymerase chain reaction in the tissue specimen, and the single antibody titer against B. henselae was greater than 1:2048. These results confirmed the diagnosis of visceral CSD caused by B. henselae. The patient's symptoms resolved after treatment with rifampin and tetracycline. This case illustrates the need for inclusion of systemic CSD in patients with fever of unknown origin and abdominal pain.

Infective endocarditis and hepatosplenic abscesses are rare manifestations of cat scratch disease (CSD), especially among immunocompetent adults. An otherwise healthy woman who presented with fever and abdominal pain was diagnosed with multiple abscesses in the spleen and the liver, as well as a mitral valve vegetation. PCR on spleen tissue was positive for Bartonella henselae. Prolonged treatment with doxycycline and gentamicin led to complete recovery. Review of the literature revealed 18 cases of hepatosplenic CSD in immunocompetent adults; the majority presented with fever of unknown origin and abdominal pain. In most cases the causative organism was B. henselae and the pathological findings were necrotizing granulomas, similar to the pathological features in classic CSD. Concomitant endocarditis was diagnosed in one case. Because Bartonella is one of the leading pathogens of culture-negative endocarditis, we raise the question of whether a comprehensive evaluation for endocarditis is needed in cases of systemic CSD.

A 46-year-old woman presented with right upper abdominal pain and fever. At imaging, enlarged peripancreatic and hilar lymph nodes, as well as hypodense liver lesions, were detected, suggestive of malignant disease. At endoscopy, the mass adjacent to the duodenum was seen as a protruding lesion through the duodenal wall. A biopsy of this lesion, taken through the duodenal wall, showed a histiocytic granulomatous inflammation with necrosis. Serology for Bartonella henselae IgM was highly elevated a few weeks after presentation, consistent with the diagnosis of cat scratch disease. Clinical symptoms subsided spontaneously and, after treatment with azithromycin, the lymphatic masses, liver lesions and duodenal ulceration disappeared completely.

Gua Sha (press-stroking) is a traditional Chinese healing technique utilized to combat pain, common cold, heatstroke, and respiratory problems. Patterned ecchymoses may appear due to the action of scraping and scratching repeatedly in a unidirectional manner, with a smooth edge over a lubricated area. They may be very informative, since they, generally, reproduce the shape of the injurious agent. However, many confounding factors can make the identification of the lesions difficult. A case of a 43 year-old Chinese woman, hospitalized for abdominal pain, is reported. An unusual pattern of reddish ecchymoses on the back was present. After a careful investigation, ecchymoses were attributed to Gua Sha. The case demonstrated that clinicians and forensic pathologists should also consider press-stroking, and other similar techniques in adults who present scratch-like marks or ecchymoses on various body districts, even if they have an unusual pattern.

Although infectious diseases are the most prevalent cause of fevers of unknown origin (FUO), this diagnosis remains challenging in some pediatric patients. Imaging exams, such as computed tomography (CT) are frequently required during the diagnostic processes. The presence of multiple hypoattenuating scattered images throughout the liver associated with the history of cohabitation with cats should raise the suspicion of the diagnosis of cat-scratch disease (CSD), although the main etiologic agent of liver abscesses in childhood is Staphylococcus aureus. Differential diagnosis by clinical and epidemiological data with Bartonella henselae is often advisable. The authors report the case of a boy aged 2 years and 9 months with 16-day history of daily fever accompanied by intermittent abdominal pain. Physical examination was unremarkable. Abdominal ultrasound performed in the initial work up was unrevealing, but an abdominal CT that was performed afterwards disclosed multiple hypoattenuating hepatic images compatible with the diagnosis of micro abscesses. Initial antibiotic regimen included cefotaxime, metronidazole, and oxacillin. Due to the epidemiology of close contact with kittens, diagnosis of CSD was considered and confirmed by serologic tests. Therefore, the initial antibiotics were replaced by clarithromycin orally for 14 days followed by fever defervescence and clinical improvement. The authors call attention to this uncommon diagnosis in a child presenting with FUO and multiple hepatic images suggestive of micro abscesses.
