Abstract:
Meningiomas combined with meningioangiomatosis (MA-M) present similarly to more invasive lesions because of their appearance on neuroimaging. These lesions are especially rare in pediatric patients and suggestive imaging can help identify them for differential diagnosis. An 11-year-old male child who presented with diplopia and a headache was found to have an edematous invasive appearing temporal lobe mass on magnetic resonance imaging. Despite the lesion's appearance, it was completely resected and found to be a benign MA-M upon histopathologic examination. The present case demonstrated a rare meningioma with meningioangiomatosis that appeared to be a higher grade or invasive lesion upon initial imaging in a pediatric patient. A review of the literature was performed on patients who presented similarly. Despite the rarity of this condition in children, neuroimaging should be carefully examined prior to surgical resection of similar masses in preparation for highly vascular tissue, and post-operative course can be better anticipated when MA-M is considered during differential diagnosis.
Insights
Meningioma with meningioangiomatosis (MA-M) can mimic invasive brain tumors in children. This rare case highlights the importance of careful neuroimaging review for accurate diagnosis and surgical planning.
Area of Science:
- Neuro-oncology
- Pediatric Neurosurgery
- Neuropathology
Background:
- Meningiomas with meningioangiomatosis (MA-M) are rare intracranial tumors.
- MA-M can present with imaging characteristics mimicking aggressive lesions.
- Pediatric cases of MA-M are exceptionally uncommon.
Observation:
- An 11-year-old male presented with diplopia and headache.
- Neuroimaging revealed an edematous, invasive-appearing temporal lobe mass.
- Histopathologic examination confirmed a benign MA-M despite aggressive imaging features.
Findings:
- This case represents a rare pediatric MA-M with deceptive neuroimaging findings.
- The lesion appeared invasive but was histopathologically benign.
- Literature review identified similar presentations in pediatric patients.
Implications:
- Careful neuroimaging analysis is crucial for MA-M diagnosis in children.
- Anticipating highly vascular tissue is essential for surgical preparation.
- Considering MA-M in differential diagnosis improves surgical planning and patient outcomes.
