Neurogenic pulmonary oedema induced by bacterial meningitis: a case report
1Medical Unit, Highland Acute Hospitals NHS Trust, Inverness. raymonddsou@yahoo.com
Abstract:
We report a case of neurogenic pulmonary oedema occurring in association with bacterial meningitis. An 87 year old man suddenly developed severe dyspnoea without cardiac failure (MUGA scan ejection fraction 47%). Radiographs showed pulmonary oedema. A few hours later he developed signs of meningitis and lumbar puncture suggested a partially treated bacterial meningitis. We suspect that the bacterial meningitis had induced neurogenic pulmonary oedema.
Insights
Neurogenic pulmonary edema can occur with bacterial meningitis. This case highlights a potential link between meningitis and lung fluid in an elderly patient.
Area of Science:
- Neurology
- Pulmonology
- Infectious Diseases
Background:
- Bacterial meningitis is a serious infection of the membranes surrounding the brain and spinal cord.
- Pulmonary edema, or fluid in the lungs, can have various causes, including cardiac failure.
Observation:
- An 87-year-old man presented with sudden, severe shortness of breath (dyspnea).
- Cardiac function was normal, as assessed by MUGA scan (ejection fraction 47%), ruling out heart failure as the cause.
- Radiographs confirmed the presence of pulmonary edema.
Findings:
- The patient subsequently developed clinical signs of meningitis.
- Lumbar puncture results indicated partially treated bacterial meningitis.
- The clinical presentation suggests bacterial meningitis as the likely cause of neurogenic pulmonary edema.
Implications:
- This case suggests a potential association between bacterial meningitis and neurogenic pulmonary edema.
- Further research is warranted to understand the mechanisms linking meningitis to pulmonary complications.
- Early recognition and management of meningitis may be crucial in preventing severe respiratory distress.
