Summary |
Objectives |
Routine vestibular schwannoma surgery can result in serious and potentially lethal infectious complications. A high degree of vigilance is necessary to diagnose these uncommon infections and in case of postoperative neurological symptoms, brain magnetic resonance imaging should be performed to eliminate a brain abscess. In some cases, the final diagnosis is not the expected one.
Clinical presentation |
A 39-year-old man presented three months postoperatively after a vestibular schwannoma removal by translabyrinthin approach with a rapid and progressive history of headaches, confusion, and left hemi paresis with fever. The brain CT and MRI were in favour of a delayed postoperative frontal abscess.
Technique |
A biopsy under stereotactic guidance was performed. Histopathologic examination revealed WHO grade 4 glioblastoma multiforme.
Conclusion |
Symptoms and signs of glioblastoma multiforme are congruent with brain abscess. Its rapid evolution, the normality of the first magnetic resonance imaging, and its radiological aspect made it a differential diagnosis of a postoperative brain abscess and should be systematically researched.
