In order to evaluate characteristics of nosocomial meningitis in adults, we performed a prospective cohort study of 50 episodes of nosocomial bacterial meningitis. These cases were confirmed by culture of cerebrospinal fluid (CSF) in patients aged >16 years. Classic symptoms of bacterial meningitis (headache, neck stiffness and fever) were present in >70% of the episodes, although only a minority (41%) presented with impairment of consciousness. Underlying conditions, such as a history of neurosurgery, recent head injury, CSF leakage or a distant focus of infection, were present in 94% of the episodes. Staphylococcus aureus was the most common pathogen in patients with a history of neurosurgery, causing 10 of 32 episodes (31%). Patients with a distant focus of infection, such as otitis, sinusitis or pneumonia were more likely to have meningitis due to Streptococcus pneumoniae than patients without [six of nine episodes (67%) vs seven of 41 (17%); P=0.01]. Complications occurred in 50% of the episodes and 16% of the patients died. Our study confirms that adults with nosocomial meningitis are a distinct patient group with specific bacterial pathogens, as compared to those with community-acquired bacterial meningitis. Underlying conditions, especially a history of neurosurgery or a distant focus of infection, were present in the large majority of patients, and mortality and morbidity rates were high.

A 55-year-old woman was admitted to our hospital complaining of severe headache with fever and apparent neck stiffness. Neutrophilic pleocytosis was demonstrated in cerebrospinal fluid (CSF) and bacterial meningitis was strongly suspected, but bacterial culture of CSF was negative. After the symptoms normalized within a few days, she developed diabetes insipidus and gadolinium (Gd)-enhancement of the enlarged hypophysis and stalk was observed on cranial MRI. A Lymphocytic Hypophysitis (LH) was clinically diagnosed. Follow-up studies demonstrated spontaneous remission of serological, radiological, and CSF findings, and she was discharged on hormonal replacement therapy with desmopressin. Three months later, she returned to our hospital complaining of headache again under adenohypophysial hypofunction and expanding pituitary lesion on MRI. CSF analysis showed meningitis but there was no evidence of infection by microorganisms. Our diagnosis was relapsing LH with aseptic meningitis, and the patient was administered methylprednisolone pulse therapy, which induced rapid improvement in clinical, endocrinological, and radiological findings. This case showed a possible unique clinical presentation of LH characterized as recurrent aseptic meningitis. It is important to recognize this phenotype of LH, and to prescribe corticosteroid therapy after appropriate endocrinological and radiological studies.

Bacterial meningitis is a life-threatening disease with a high mortality if left untreated. School-age children, adolescents and adults often present with typical symptoms such as fever, headache, neck stiffness and altered mental status, whereas infants show rather unspecific symptoms.The important task of the primary physician is to recognize the life-threatening condition in time and to refer the patient immediately to the next hospital.

A 22-year-old man with incessant ventricular tachycardia (VT) associated with pneumococcal meningitis without obvious heart disease manifesting as febrile sensation and severe headache visited our emergency department. Initial electrocardiography showed ventricular premature couplets, but the rhythm grew more serious and developed into incessant monomorphic VT resulting in an electrical storm. After examining the cerebrospinal fluid, bacterial meningitis was suspected. The electrical storm ended 21 hr after he had received conservative treatment for meningitis. Streptococcus pneumonia was cultured from the cerebrospinal fluid. No VT was observed during the remainder of the hospital stay and could not be induced in the electrophysiological study.

A 47-year-old man presented with headache, nausea, vomiting and fever. Laboratory findings including analysis of cerebrospinal fluid suggested bacterial meningitis. Erysipelothrix rhusiopathiae was identified in cultures of cerebrospinal fluid. The patient recovered without any neurological sequelae after antimicrobial treatment. It is interesting that intracranial infection by E. rhusiopathiae reappeared after scores of years and that it presented with absence of an underlying cause or bacteraemia.

A 77-year-old woman was admitted suffering from fever and headache. On laboratory examination, bacterial meningitis and sepsis due to Klebsiella pneumoniae were diagnosed. In addition, a hepatic cystic lesion measuring 13 cm in diameter in the left lobe was indicated on diagnostic imaging. After treatment with antibiotics, her signs of infection improved and the hepatic lesion decreased in size. After discharge, however, the cystic liver mass increased and a gastric fistula developed. Hepatic and gastric resections were performed because of the possibility of biliary cystadenocarcinoma and gastric invasion. Pathologically, a pyogenic liver abscess complicated by gastric fistula was diagnosed.

A 29-year-old woman, who was diagnosed as Crouzon syndrome for which two cranio-facial surgeries had been performed as a child and at the age of 19, developed high fever, headache, and confusion for two days. She was admitted to our hospital. She was diagnosed as bacterial meningitis by cerebrospinal fluid examinations, and her condition was immediately improved by antibiotics. At the age of 23, she also suffered from bacterial meningitis caused by otitis media and sinusitis, and recovered by antibiotics with no sequela. Her cranial computed tomography showed sphenoid and ethmoid sinusitis, and bone deformation and hypertrophy with no fistula connecting intracranial space and sinus. Dead space by cranio-facial surgeries might cause the development of chronic or recurrent sinusitis leading to bacterial meningitis. Our patient is the second case of recurrent bacterial meningitis with Crouzon syndrome to our knowledge. We should recognize that recurrent sinusitis with Crouzon syndrome after cranio-facial surgery is a risk of recurrent meningitis.

We report the case of a 69-year-old female who presented with headache, stiff neck, and decreased level of consciousness. Lumbar puncture results were typical of bacterial meningitis. Blood and cerebrospinal fluid cultures showed Streptococcus bovis. Subsequent serologic studies indicated concurrent Strongyloides stercoralis infection, and larvae were visualized in two separate stool specimens. The patient responded to treatment of both infections. She refused to undergo colonoscopy despite a known association between Streptococcus bovis and colonic carcinoma.

Millions of patients see physicians each year for headache, most of which are primary headaches. However, serious secondary headaches, such as meningitis, represent about 5% of children and 1% to 2% of adults seen in the emergency department for headache. A primary care or emergency department physician may initially miss individuals with bacterial meningitis. Considering meningitis as a headache cause is important because delay in the diagnosis may have adverse consequences. A careful history and physical examination are central in identifying individuals at high risk for meningitis. This article lists information that can be obtained from the patient that may be indicative of meningitis. Performing a lumbar puncture with appropriate examination of the cerebrospinal fluid (CSF) is the key to establishing the diagnosis of meningitis. This article also includes the types of meningitis that should be considered when the CSF demonstrates a pleocytosis.

Non-enteric salmonella infections in immunocompetent adults are exceedingly rare in the United States, and meningitis is one of the least common extra-intestinal sites. In addition, it is very unusual for a patient with bacterial meningitis to present with classic meningitis signs and symptoms of > 72 h duration. The objective of this work is to describe a rare case of salmonella meningitis in an immunocompetent adult and, in the context of previously published case reports, describe the frequently atypical clinical course of salmonella meningitis along with the potential pitfalls encountered during its evaluation and treatment. An otherwise healthy 45-year-old man presented to our Emergency Department with frontal headache, fever, and stiff neck of 7 days duration. He was alert and oriented in triage, where he was noted to be afebrile, mildly tachycardic, with a normal blood pressure and respiratory rate; shortly after triage he developed a high fever, severe tachycardia, hypotension, and a change in mental status. He was resuscitated according to our severe sepsis protocol and treated empirically for bacterial meningitis. Blood and cerebrospinal fluid cultures grew group D Salmonella berta. An evaluation for underlying immunodeficiency was unrevealing. The patient was discharged home on hospital day 7 in good condition. Salmonella meningitis can present with an indolent course and can mimic, in many misleading ways, the less serious diagnosis of aseptic meningitis. This case highlights the need for an unbiased clinical assessment, aggressive management of critical illness, and point-for-point correspondence between clinical data and assigned diagnosis.
