Chronic headache and bilateral papilledema unveil olfactory groove meningioma

Meningiomas are common intracranial tumours that originate from the meninges. Olfactory groove meningiomas (OGMs), while relatively rare, can present with a variety of nonspecific symptoms due to their location and the resulting mass effect on adjacent brain structures. OGMs are distinguished from other frontal meningiomas by their origin near the cribriform plate and their frequent presentation with anosmia; however, not all patients exhibit this symptom. OGM is primarily a radiological diagnosis confirmed by imaging features and location. Headaches are a frequent initial complaint, often accompanied by symptoms related to increased intracranial pressure such as vomiting and papilledema. This case report describes the presentation, diagnostic workup, and successful surgical treatment of a 37-year-old female with chronic headache caused by a large OGM. It highlights the importance of thorough clinical evaluation and imaging in patients with persistent headaches and demonstrates the effectiveness of timely surgical management for such tumours.
