Meningiomas are the most common benign intracranial tumour and show a rising incidence with age. They present with a wide array of symptoms and, in this paper, we discuss a case report of an intracranial meningioma presenting as paraesthesia of the lower left lip and chin region. Coincidentally, the symptoms manifested soon after a course of routine dental treatment, further complicating the diagnosis of the lesion. This case highlights the importance, to clinicians at all levels, of the wide array of causes of nerve paraesthesia within the orofacial region and how less frequently occurring conditions must be considered at an early stage.
Clinical Relevance: Intracranial lesions should be included in the differential diagnosis of paraesthesia or anaesthesia of a localized area.
Article
Meningiomas grow slowly from the arachnoid cap cells1 and most commonly occur in the venous sinuses and the skull base,2 around the sixth and seventh decade of life. According to the fourth edition of the World Health Organization (WHO) Classification of Tumours of the Central Nervous System, published in 2007, there are 15 types of meningiomas of which only one variant is malignant.3 They are the most frequently diagnosed intracranial tumour and represent 13–26% of all intracranial tumours.4 In adults, there is a marked female bias with a female:male ratio of 3:2 to 2:1.5
The incidence of meningiomas is increasing over time, particularly in the elderly, and in a large autopsy series it was as high as 1.4%.6 This increase is related to wider indications for cranial imaging, better imaging facilities and ageing populations.
