Welcome to your Long Case 04: Meningitis

A 22-year-old university student living in a hostel presents with high-grade fever, severe diffuse headache and repeated vomiting for two days. His family reports increasing neck stiffness and drowsiness during the last six hours. Which additional historical feature would most strongly support an acute bacterial rather than tuberculous meningitis presentation?

Progressive headache over three weeks with weight loss

Evening fever associated with persistent night sweats

Gradual development of diplopia over several weeks

Rapid deterioration in consciousness within 24–48 hours

Chronic low-grade fever with prolonged constitutional symptoms

None

A 21-year-old man presents with fever, severe headache, vomiting and neck stiffness. He shares a university hostel room with three other students. The physician specifically asks about similar illnesses among his roommates and recent close contact with anyone diagnosed with meningitis. What is the main clinical significance of this information?

It helps assess possible meningococcal exposure and the need for contact management

It establishes that the patient has tuberculous meningitis

It determines whether lumbar puncture is contraindicated

It confirms that the infection originated from a middle ear infection

It identifies the presence of raised intracranial pressure

None

A 28-year-old man presents with headache, fever and vomiting for 18 days. He reports progressive weight loss, night sweats and increasing difficulty concentrating. His family notices intermittent double vision. Examination reveals neck stiffness and a right sixth cranial nerve palsy. Which diagnosis best explains this clinical pattern?

Acute meningococcal meningitis

Uncomplicated viral meningitis

Acute pyogenic meningitis

Subarachnoid hemorrhage

Tuberculous meningitis

None

A 22-year-old man with suspected meningitis is febrile and drowsy. He opens his eyes when spoken to, answers questions appropriately and obeys commands. There is no focal neurological deficit. Which Glasgow Coma Scale score most accurately represents his level of consciousness?

GCS 13/15

GCS 14/15

GCS 10/15

GCS 15/15

None

A 23-year-old man presents with fever, severe headache and photophobia. Examination reveals resistance to passive neck flexion. When his hip is flexed, extension of the knee produces pain and resistance. Which interpretation of this examination finding is most appropriate?

It indicates a focal upper motor neuron lesion

It supports meningeal irritation but is not diagnostic on its own

It confirms raised intracranial pressure

It establishes bacterial rather than viral meningitis

It indicates spinal cord compression

None

A 24-year-old man is admitted with suspected acute bacterial meningitis. Initially, he is alert with neck stiffness and fever. Several hours later, he becomes increasingly drowsy and develops unequal pupils and weakness of his left arm. Which clinical interpretation is most appropriate?

The findings indicate expected recovery from meningeal inflammation

The neurological findings confirm uncomplicated viral meningitis

The findings establish an isolated peripheral nerve disorder

The findings indicate a normal post-treatment neurological response

The findings suggest a serious intracranial complication requiring urgent assessment

None

A 22-year-old hostel resident develops high-grade fever, severe headache, vomiting, photophobia and neck stiffness over two days.

Which diagnosis is most likely at initial assessment?

Acute bacterial meningitis

Tuberculous meningitis

Uncomplicated migraine

Chronic viral encephalitis

Primary tension-type headache

None

A 25-year-old man presents with sudden severe headache, vomiting and neck stiffness. The headache reached maximum intensity within seconds while he was exercising. He has no preceding febrile illness. His temperature is normal, but he appears distressed. Which alternative diagnosis must be urgently considered before attributing the symptoms to meningitis?

Tuberculous meningitis

Uncomplicated viral meningitis

Chronic bacterial meningitis

Subarachnoid hemorrhage

Tension-type headache

None

A 23-year-old man presents with fever, headache and altered behavior. His family reports progressive confusion, recent abnormal emotional outbursts and a generalized seizure. Neck stiffness is mild. Which diagnosis should be considered particularly strongly because of the prominent cerebral dysfunction?

Encephalitis or meningoencephalitis

Isolated cervical muscle spasm

Primary migraine without aura

Acute bacterial sinusitis without CNS involvement

None

10.

A 22-year-old man with acute meningitis undergoes lumbar puncture after appropriate clinical assessment. CSF is turbid, with 1,800 white cells/µL, 90% neutrophils, protein 180 mg/dL and glucose 25 mg/dL. Simultaneous blood glucose is 100 mg/dL. Which interpretation best integrates these findings?

A typical uncomplicated viral meningitis pattern

Normal CSF findings for a young adult

A CSF pattern suggesting isolated intracranial hemorrhage

A typical noninfectious headache-associated CSF pattern

A CSF pattern strongly supporting acute bacterial meningitis

None

11.

A 22-year-old hostel resident is diagnosed clinically with acute bacterial meningitis. CSF demonstrates neutrophilic pleocytosis, elevated protein and reduced glucose. Gram staining reveals Gram-negative diplococci. Which causative organism is most strongly suggested by this combination of findings?

Streptococcus pneumoniae

Mycobacterium tuberculosis

Neisseria meningitidis

Haemophilus influenzae

Listeria monocytogenes

None

12.

A 21-year-old man presents with fever, headache and neck stiffness. Lumbar puncture reveals clear CSF with 180 white cells/µL, predominantly lymphocytes, mildly elevated protein and normal CSF glucose relative to blood glucose. He remains alert and hemodynamically stable. Which diagnosis is most consistent with this investigation pattern?

Viral meningitis

Acute pyogenic meningitis

Meningococcal septicemia

Tuberculous meningitis

Intracranial bacterial abscess

None

13.

A 30-year-old man presents with three weeks of headache, low-grade fever, vomiting and progressive drowsiness. CSF shows predominantly lymphocytic pleocytosis, markedly elevated protein and reduced glucose. MRI demonstrates basal meningeal enhancement with hydrocephalus. Which interpretation best integrates these findings?

Uncomplicated viral meningitis with spontaneous recovery

Acute meningococcal infection without neurological complications

Primary migraine associated with incidental CSF abnormalities

Tuberculous meningitis with impaired CSF circulation

Normal inflammatory changes following a generalized seizure

None

14.

A 22-year-old man presents with fever, severe headache, vomiting and neck stiffness. Acute bacterial meningitis is strongly suspected. He is drowsy, and the clinical team decides that lumbar puncture requires further safety assessment. Blood cultures have been obtained without delaying care. Which management decision is most appropriate?

Wait for CSF culture confirmation before prescribing antibiotics

Start appropriate empirical intravenous antibiotics immediately

Delay antimicrobial treatment until MRI excludes all neurological complications

Prescribe oral analgesics and reassess after 24 hours

Perform lumbar puncture despite unresolved safety concerns

None
