Abstract:
Low-grade (WHO level I) meningiomas are slow-growing, benign tumours typically presenting with unspecific symptoms (e.g. headache), seizures, cranial nerve compression and neuropsychological symptoms determined by location and size of the lesion. Haemorrhagic onset and sequelae are rare, and have been described infrequently. This is a case of a 50-year-old male presenting with signs of tentorial herniation secondary to hyperacute intratumoural haemorrhage (ITH) into a previously undiagnosed meningioma. Emergency surgical decompression and exstirpation of the lesion helped to achieve a favourable outcome. ITH has been described in all including benign intracranial neoplasms. Factors associated with a higher risk for haemorrhage in meningiomas are discussed. Though haemorrhages associated with meningiomas have been reported, ITH into low-grade meningiomas leading to herniation remains a rarity. Bearers of known lesions and their treating physicians who opt for conservative or delayed treatment should be aware of this remote complication.
Insights
A rare case of intratumoural haemorrhage (ITH) in a low-grade meningioma caused tentorial herniation. Emergency surgery led to a positive outcome, highlighting a rare complication of benign brain tumors.
Area of Science:
- Neurology
- Neurosurgery
- Oncology
Background:
- Low-grade (WHO level I) meningiomas are typically benign and slow-growing brain tumors.
- Common symptoms include headaches, seizures, and cranial nerve compression, varying with tumor size and location.
- Intratumoural haemorrhage (ITH) is an infrequent complication of meningiomas, particularly low-grade ones.
Observation:
- A 50-year-old male presented with signs of tentorial herniation due to acute ITH in an undiagnosed meningioma.
- The patient experienced a hyperacute onset of symptoms.
- Emergency surgical decompression and tumor removal were performed.
Findings:
- The case highlights a rare instance of ITH in a low-grade meningioma leading to life-threatening tentorial herniation.
- Factors contributing to hemorrhage risk in meningiomas are discussed.
- Despite the rarity, ITH is a potential complication across all intracranial neoplasms, including benign types.
Implications:
- This case underscores the importance of recognizing ITH as a rare but severe complication of meningiomas.
- Physicians and patients with known meningiomas should be aware of this potential, even with conservative management.
- Prompt surgical intervention is crucial for favorable outcomes in cases of symptomatic ITH with herniation.
