A 12-year-old Bedouin boy presented with sudden asymmetrical status epilepticus. The presence of a scalp wound, rubbery cervical lymphadenopathy and a history of contact with cats suggested the diagnosis of cat-scratch disease complicated by encephalopathy. The diagnosis was supported by histological examination of a cervical lymph node and a positive skin test with cat-scratch antigen. The rapid establishment of the diagnosis avoided the necessity of elaborate and complicated neuroradiological investigations.

Cat scratch disease is a subacute regional lymphadenitis usually preceded by a history of being scratched by a cat or young kitten. The spectrum of illness ranges from mild self-limited adenopathy to severe systemic disease, including hepatosplenomegaly, encephalopathy, osteolytic lesions, splenic abscesses, mediastinal masses, and neuroretinitis. Vision loss is a rare complication of the disease. The authors report a patient with cat scratch disease associated with acute febrile illness, lymphocytic meningitis, and acute vision loss secondary to neuroretinitis. To their knowledge, this is the first ophthalmic case reported in which the diagnosis is supported by both a positive skin test and positive histopathology.

We described a eight-year-old girl with encephalopathy due to cat scratch disease. Cat scratch disease is a common cause of benign, self-limited, regional adenopathy seen among young people. Encephalopathy is uncommon but is a serious complication of cat scratch disease. Cat scratch disease with associated encephalopathy was described by Stevens in 1952. Since then there have been reports of only 39 cases in the English literature. As far as we know, this case is the first case in Japan. In cases of a rapidly progressive encephalopathy, the diagnosis of cat scratch disease should be considered.

Seventy-six patients with neurologic complications of cat-scratch disease are discussed. Encephalopathy occurred in 61, while 15 had either cranial or peripheral nerve involvement. The average age of the patients with encephalopathy was 10.6 years (range, 1 to 66 years), and almost twice as many males as females were affected in contrast to patients with uncomplicated cat-scratch disease, in which the ratio was almost equal. Fever was not documented in 50% of patients with encephalopathy and only 26% had temperatures higher than 39 degrees C. Convulsions occurred in 46% and combative behavior in 40%. Lethargy with or without coma was accompanied by variable neurologic signs. Results of laboratory studies, including imaging of the central nervous system, were inconsistent and nondiagnostic. Biopsy tissue from 14 patients showed histopathologic findings compatible with cat-scratch disease. The "English-Wear bacillus" was demonstrated by the Warthin-Starry stain in 10 of 14 skin or lymph node specimens. Of the 15 patients without encephalopathy, two children with facial nerve paresis displayed cranial nerve symptoms and/or signs, 10 patients had cat-scratch disease neuroretinitis, and three women had peripheral neuritis. All 76 patients recovered within 12 months; 78% recovered within 1 to 12 weeks. There were no neurologic sequelae. Treatment consisted of control of convulsions and supportive measures. Commonly used antibiotics administered to more than half of the patients were apparently ineffective.

Cat scratch disease is usually benign, self-limited and without sequelae. Margileth has established four clinical criteria, three of which must be satisfied to make the diagnosis: 1) a history of animal exposure, usually kitten, with primary skin or ocular lesions; 2) regional chronic adenopathy without other apparent cause; 3) a positive cat scratch disease antigen skin test; and 4) lymph node biopsy demonstrating noncaseating granulomas and germinal center hyperplasia. Central nervous system involvement in cat scratch disease has been previously reported, although it is extremely uncommon. In a several-month period, we encountered two cases of cat scratch disease complicated by encephalopathy. The intents of this paper are twofold: 1) to briefly review the current literature on cat scratch disease, 2) to demonstrate that cat scratch disease complicated by encephalopathy presents acutely with seizures, posturing and coma and resolves rapidly with supportive care.

A five-year-old male was admitted to the hospital with generalized seizures. Enlarged lymph nodes raised the suspicion of cat-scratch disease. The diagnosis was confirmed by a positive history of a cat bite, typical histopathologic findings in the biopsy of the lymph nodes, and a positive skin test. Brain CT scan and LP were repeatedly normal. The clinical course was remarkable for recurrent episodes of status epilepticus refractory to usual anticonvulsant therapy and prolonged encephalopathy consisting of mental confusion, hemiparesis, tremor, chorea, and vomiting. All neurologic symptoms gradually resolved within nine months, without sequelae. Cat-scratch encephalopathy should be suspected in a child presenting with status epilepticus and enlarged lymph nodes. Aggressive and prolonged anticonvulsant therapy is strongly recommended.

A case of cat-scratch disease (CSD) complicated by reversible encephalopathy is presented. Neurological complications of CSD are uncommon. Laboratory and radiological examinations were negative. There was complete recovery.

A patient with optic neuritis is described whose associated lymphadenopathy, cat exposure, and positive cat scratch antigen skin test suggested the diagnosis of cat scratch disease. Optic neuritis and other neurologic abnormalities, especially encephalopathy, may be associated with, or the presenting manifestation of, cat scratch disease. To our knowledge, this is the fourth case of cat scratch disease-related optic neuritis to be reported.

Cat scratch disease is a relatively common cause of chronic (three weeks or longer) lymphadenopathy, with 80% of cases occurring in children and adolescents. This self-limited infection caused by a small, gram-negative, pleomorphic bacillus has been identified in ocular granuloma, skin inoculation lesions, and lymph node specimens. Dermatologic manifestations observed prospectively in 908 patients included primary cat scratch inoculation papules, pustules or rarely, vesicles. Occasionally, enanthematous mucous membrane (oral, ocular) primary inoculation lesions were observed. About 5% of patients have generalized macular, maculopapular, morbilliform, and rarely petechial, usually nonpruritic exanthem. Rarely, erythema nodosum or multiforme and ecchymoses with petechial rashes are seen. Thrombocytopenic purpura is extremely uncommon. Unusual manifestations such as the oculoglandular syndrome of Parinaud, encephalopathy, or severe systemic disease occur in about 10% of patients. Management consists of symptomatic treatment and occasional aspiration of a suppurative node. The disease usually resolves spontaneously in two to four months.

We describe a renal allograft recipient with cat-scratch disease in whom refractory hypotension, severe metabolic acidosis, pulmonary infiltrates, and encephalopathy developed. The patient first presented with a history of cat bites and scratches, fever, headache, and arthralgias. Four weeks later, the clinical presentation of septic shock suddenly developed in the patient. Cat-scratch disease was documented clinically and by finding delicate pleomorphic bacilli in Warthin-Starry silver stains of biopsy specimens taken from the primary inoculation site and regional lymph node. The administration of intravenous sulfamethoxazole and trimethoprim, erythromycin lactobionate, and tobramycin sulfate therapy correlated with recovery. Although cat-scratch disease is usually a benign, self-limited illness, this article illustrates its systemic nature, its potential for devastating complications in the immunocompromised host, and its possible response to vigorous antibiotic therapy.
