Summary
Brain abscesses within brain metastases are rare but life-threatening. This study details a case of lung adenocarcinoma metastasis presenting as a brain abscess, emphasizing early recognition for treatment.
Area of Science:
- Neurosurgery
- Oncology
- Infectious Diseases
Background:
- Brain abscesses are serious infections with a high mortality rate.
- Metastasis to the brain is common in many cancers.
- Abscess formation within brain metastases is an exceptionally rare occurrence.
Observation:
- A 64-year-old female presented with neurological deficits and headache.
- Imaging revealed a right frontal lobe tumor with characteristics suggestive of metastasis.
- A primary lung tumor and adrenal metastasis were identified.
Findings:
- Histopathology confirmed metastatic lung adenocarcinoma.
- Purulent material within the tumor indicated abscess formation.
- Cultures identified Staphylococcus epidermidis and Streptococcus mitis.
Implications:
- Abscesses within brain metastases are difficult to diagnose preoperatively due to non-specific features.
- Early recognition is critical for appropriate management and improved patient outcomes.
- This case highlights the importance of considering abscess formation in metastatic lesions.
