A 28-year-old woman with systemic lupus erythematosus (SLE) suffered recent onset fever, headache, encephalopathy followed by severe, repeated generalized seizures. Investigations revealed limbic encephalitis. Tests for Herpes simplex encephalitis and paraneoplastic encephalomyelitis were negative. High titers anti-ribosomal-P antibodies in the cerebrospinal fluid (CSF) suggested an association with nervous system lupus. No brain biopsy was performed. Treatment was with anti-seizure, anti-viral, and immunomodulating medication.

In recent years, the frequency of primary cerebral lymphoma (PCNSL) has increased, even among immunocompetent patients. In order to treat the disease optimally, early diagnosis is important. We present three patients with atypical courses of this disease and stress the importance of PCNSL in the differential diagnosis for optimal treatment. In a 75-year-old man, a space-occupying, radiopaque, enhancing CNS lesion disappeared completely after biopsy and short steroid therapy. One year later, the tumor recurred on the other side and again regressed after steroid therapy. The first biopsy showed signs of a papillary tumor, so a choroid plexus papilloma was suspected initially. A 57-year-old woman developed progressive bilateral hearing dysfunction. Lymphocytic pleocytosis led to a primary diagnosis of chronic lymphocytic meningitis. During the further course of disease, the patient developed multiple space-occupying cerebral lesions. Stereotactic biopsy revealed PCNSL. Despite combined chemo- and radiotherapy, a relapse occurred. A 49-year-old woman rapidly developed memory and concentration disturbances. Computed tomography revealed diffuse edema in both hemispheres and MRI detected severe, diffuse, white matter lesions. The CSF revealed lymphocytic pleocytosis including plasma cells. Herpes encephalitis and, after lack of clinical improvement and progression of the MRI changes, acute disseminated encephalomyelitis (ADEM) were suspected. Corticosteroid treatment was initiated. After enormous clinical improvement, a clinical relapse occurred and MRI detected bitemporal and singular space-occupying lesions in the corpus callosum and hypothalamus. Finally, open biopsy showed PCNSL. However, on examination of the treatment history of patient 1, the initial diagnosis must be revised; a PCNSL seems most probable. The phenomenon of tumor remission under steroid administration is rare. In patients 2 and 3, atypical clinical signs and symptoms delayed diagnosis of PCNSL. This tumor can mimic diverse neurological diseases and remit following corticosteroid treatment alone. In unclear cerebral disease, biopsy should be performed early for exact diagnosis and optimal treatment.

Cat scratch disease (CSD) is a zoonotic illness caused by the Gram negative bacillus Bartonella henselae characterized by a small skin lesion at the site of a bite, lick or scratch by a cat, commonly followed by regional lymphadenopathy 1 or 2 weeks later. We report herein on severe neurological complications of CSD combining brainstem encephalopathy and basal ganglia impairment. This 12-year-old female acutely presented to a local hospital with profound coma and a prolonged tonic posturing of extremities. On the neurological examination she was deeply comatose with pin-point pupils and lack of vestibulo-ocular responses, suggestive of brainstem encephalopathy, along with marked rigid hypertonicity suggestive also of basal ganglia impairment. Initially suspecting Herpes simplex encephalitis or acute disseminated encephalomyelitis she was promptly started with high-dose methyl-prednisolone and acyclovir. Her parents apparently reported that she was scratched by a kitten some 4 weeks prior to her present admission and as such, suspecting CSD, she was begun with doxycycline and rifampicin. Her serology had proven positive for IgM antibodies to Bartonella henselae establishing the diagnosis. She regained consciousness after 4 days and the signs of brainstem and extra-pyramidal impairment also gradually abated and disappeared after 10 days. A follow-up exam after a month disclosed mild extra-pyramidal abnormalities which disappeared after 3 months. Although extremely rare, CSD should be also considered in a patient presenting with a severe encephalopathy and associated basal ganglia impairment. The prompt administration of high-dose methyl-prednisolone upon admission may have contributed to the favorable outcome in our patient and therefore should be advocated in any patient presenting with profound encephalopathy regardless the underlying etiology recovered later.

We experienced a right-handed 53-year-old man who presented with disturbance of consciousness and fever. Herpes simplex encephalitis (HSE) was diagnosed based on the detection of herpes simplex virus DNA in the cerebrospinal fluid. The administration of acyclovir for 42 days improved his consciousness level. Drowsiness, fever and seizures reappeared 20 days after stopping acyclovir treatment (day 67) and he responded well to vidarabine and methylprednisolone pulse therapy. An assessment of aphasia on day 98 revealed transcortical sensory aphasia. Brain MRI showed lesion in the left temporal lobe, bilateral insular cortexes and bilateral frontal lobe. His higher brain dysfunction continued. On day 156, he underwent hip replacement arthroplasty under general anesthesia sevoflurane. His higher brain dysfunction rapidly improved thereafter. We concluded that the accelerated improvement in our patient's higher brain function was related to the protective effect of sevoflurane. Some reports also show the protective effects of sevoflurane in experimental allergic encephalomyelitis by inhibition of T cell activation. These protective and anti-inflammatory effects may explain the accelerated improvement in higher brain function after general anesthesia.
