1/11. Listeria meningoencephalitis: two cases and a review of the literature.

    INTRODUCTION: Although presently uncommon locally, Listeria is increasing an important cause of central nervous system (CNS) infection worldwide. It differs from the common meningitis pathogens in its clinical features and treatment. CLINICAL PICTURE: We present 2 recently encountered cases of Listeria meningoencephalitis. In case 1, a previously healthy 42-year-old man presented with clinical features of meningoencephalitis. In case 2, a 64-year-old woman had clinical features of pneumonia and meningoencephalitis. Both had a predominantly lymphocytic picture in their cerebrospinal fluid (CSF) samples. Listeria grew in blood cultures of both patients and the CSF culture of the first. TREATMENT: In both cases, Listeria was resistant to the empirical antibiotics used. Intravenous ampicillin was eventually used in both patients, with gentamicin, added for synergistic action in the first. OUTCOME: The first patient developed complications of hydrocephalus, subdural collection and extensive cerebritis and ventriculitis. The second patient had focal seizures and a pontine infarct. Both did not survive. CONCLUSION: These 2 recent cases with different presentations of intracranial listerosis highlight the increasing importance of listerial infections in singapore. Clinicians need to be familiar with the features of this lethal disease in order to recognize and manage it successfully.

2/11. A case report of sporadic ovine listerial menigoencephalitis in iowa with an overview of livestock and human cases.

    A case of ovine listeriosis was examined in a flock of sheep. The index case was a male lamb, which was part of a flock of 85 sheep located in central iowa. Because the sheep were raised on a premise where soybean sprouts were also cultivated for the organic foods market, the potential of a public health concern was addressed. To identify the source of contaminations, clinical and environmental samples were cultured for listeria monocytogenes. Isolates were serotyped and analyzed using pulsed-field gel electrophoresis (PFGE). listeria monocytogenes (serotype 1) was recovered from the brain of a male lamb with clinical signs of listerial encephalitis. Isolates of serotypes 1 and 4 were also cultured from feces of clinically healthy lambs, compost piles, and soybean cleanings. By PFGE, the clinical isolate was distinctly different from the other isolates. Environmental isolates were identified as L. monocytogenes serotypes 1 and 4. However, by PFGE, none matched the profile of the single clinical isolate. Thus, the ultimate source of contamination is unknown.

3/11. syringomyelia following Listeria meningoencephalitis: report of a case.

    A case of symptomatic syringomyelia which appeared six years after Listeria meningoencephalitis is described. Chronic spinal arachnoiditis, as shown by standard MRI and dynamic phase contrast (PC) cine-MRI, may occur after spinal infection and is likely the cause of syringomyelia. To our knowledge, there are no previous reports of delayed spinal complications following listeria monocytogenes infection. The possibility of developing syringomyelia should be always considered in any patient with a history of central nervous system infection.

4/11. Neurolisteriosis causing hydrocephalus, trapped fourth ventricle, hindbrain herniation and syringomyelia.

    Central nervous system infection by listeria monocytogenes is relatively uncommon, but is known to be highly morbid and fatal. We describe a case of listeria meningoencephalitis, wherein the acute episode was followed by a hitherto unreported conglomeration of severe and progressive neurological sequelae, in the form of supratentorial hydrocephalus, aqueduct block, trapped fourth ventricle, hindbrain herniation and syringomyelia. Pertinent literature is reviewed and the pathogenesis of the observed sequelae is explored.

5/11. Neurolisteriosis mimicking herpes simplex encephalitis in an immunocompromized patient.

    brain MRI was performed in an immunocompromized febrile and lethargic patient, revealing an asymmetric bilateral temporal lobe involvement, strongly suggestive of herpetic encephalitis. Nevertheless, PCR in CSF for Listeria monocytogens was positive. This case implies that Listeria might be considered in patients with clinical and imaging suspicion of herpetic encephalitis.

6/11. Cerebral listeriosis in adults. Three cases report.

    The Authors describe three autoptic cases of meningoencephalitis in adults due to an emerging pathogen, the Gram-positive bacillus listeria monocytogenes. Only one of these was an immunosuppressed patient (recurrent carcinoma of the larynx and bladder papillomas), while no severe cause of debilitation was detected in the other two cases, excluding colonic diverticulosis in both. The post-mortem examination revealed leptomeningitis and encephalitis. Lympho-monocytic tissue reaction with perivascular cuffing was present in all the cases. The etiologic agent, L. monocytogenes, was identified by cultures from clinical or autoptic specimens.

7/11. Symptomatic hydrocephalus and reversible spinal cord compression in listeria monocytogenes meningitis. Case report.

    central nervous system infections with listeria monocytogenes result in varied clinical syndromes ranging from meningitis to rhomboencephalitis. A case of Listeria meningitis complicated by symptomatic communicating hydrocephalus and hydrostatic cervical cord compression is presented which clinically and radiographically improved with aggressive ventricular drainage.

8/11. Positive bromide partition test in the absence of tuberculous meningitis.

    Five cases of lymphocytic meningitis are described where a Bromide Partition Test was performed and proved positive at levels usually considered consistent with tuberculous meningitis. Three of these cases were ultimately shown to have herpes simplex viral encephalitis, one had listeria monocytogenes in the CSF and the fifth patient recovered without treatment and was thought to have had a viral encephalitis. The Bromide Partition Test may not be as good a discriminant as has previously been suggested in differentiating between tuberculous and viral meningitis, especially when performed in a population at low risk of getting tuberculous meningitis.

9/11. Primary aldosteronism associated with a primary double cancer of the thyroid and rectum: report of a case.

    A variety of complications are encountered in primary aldosteronism. Among them, less well known is the association of functioning adrenocortical adenoma with neoplasia of other organs. Described here is a patient with primary aldosteronism who had undergone a surgical operation for thyroid cancer and died of meningoencephalitis due to listeria monocytogenes. Moreover, the autopsy revealed that he had an adenocarcinoma of the rectum. To our knowledge, this is the first documented case of a patient who had both primary aldosteronism and a primary double cancer of the thyroid and rectum.

10/11. Diagnostic ultrastructure of listeria monocytogenes in human central nervous tissue.

    The pathogenesis of listeria monocytogenes infection of the human central nervous system is poorly understood and ultrastructural aspects are not documented. A case of fatal human L. monocytogenes meningoencephalitis is described, in which diagnosis was confirmed by blood culture and in which special staining (Brown's) showed slender gram-positive bacilli in inflamed areas of the brainstem at autopsy. Electron microscopy of blocks rescued from formalin revealed rods, up to 2.5 microns long x 0.4 microns in diameter, with gram-positive type cell walls and distinctive conic ends, the latter being apparent in axial section only. The organism was either free within the cytoplasm or within endosomes or phagosomes of macrophages, smooth muscle cells, and endothelial cells. In one instance, one was seen adhering to the luminal aspect of the vascular endothelium. Central nervous system parenchymal cell infection was suspected but not confirmed. Intra-cytoplasmic bacteria were surrounded by an electron-transparent halo and, beyond that, a cloud of host-derived microfilaments, as previously described by others in vitro and in animals. The morphology of L. monocytogenes is compared with that of other intracellular pathogens and is found to be distinctive, suggesting the value of ultrastructural study in diagnosis. Such work could also help to solve outstanding pathogenetic questions of central nervous system invasion and spread.
