Abstract:
We present a case of a 30-year-old male patient who was admitted to our institution with a 4-month history of persistent headache, pain in the left half of the face and the left ear. The initial magnetic resonance imaging detected an inflammatory process in the left pyramid interpreted as petrous apicitis. Subsequently, he developed generalized seizures. Follow-up computed tomography scanning with contrast enhancement demonstrated newly-formed brain abscess in the basal region of the left temporal lobe. The patient underwent microsurgical evacuation and resection of the abscess. Microbiological examination isolated Paenibacillus lactis as a causative microorganism. During the postoperative period, the patient further developed life-threatening meningitis that was successfully managed with prolonged intravenous antimicrobial treatment. Six-months follow-up examination confirmed complete neurological recovery with no signs of recurrence based on Magnetic Resonance Imaging (MRI). To the best of our knowledge, this is the first reported case of brain abscess caused by Paenibacillus lactis in the medical literature.
Insights
This case report details a rare brain abscess caused by Paenibacillus lactis in a 30-year-old male. The patient recovered fully after surgical intervention and antimicrobial treatment for the abscess and subsequent meningitis.
Area of Science:
- Neurology
- Infectious Diseases
- Microbiology
Background:
- Petrous apicitis can present with complex neurological symptoms.
- Brain abscesses are serious intracranial infections requiring prompt diagnosis and management.
Observation:
- A 30-year-old male presented with headache, facial pain, and otalgia, initially diagnosed with petrous apicitis.
- Magnetic resonance imaging revealed an inflammatory process, followed by computed tomography showing a temporal lobe brain abscess.
- The patient experienced generalized seizures and later developed meningitis post-abscess evacuation.
Findings:
- Paenibacillus lactis was identified as the causative agent of the brain abscess.
- Surgical evacuation and resection of the abscess were performed.
- Prolonged intravenous antimicrobial therapy successfully treated the meningitis.
Implications:
- This is the first reported case of a brain abscess caused by Paenibacillus lactis.
- Highlights the importance of considering rare pathogens in brain abscess etiology.
- Emphasizes the need for comprehensive management of associated complications like meningitis.
