Intracranial Meningioma in a Patient with ABPA: A Case Report and Literature Review

Meningiomas are the most common primary intracranial tumours, accounting for about 36% of central nervous system neoplasms. Arising from arachnoid cap cells, they are typically benign, slow-growing, and often found incidentally, though symptoms may occur from compression of nearby neural structures. We present a case of intracranial meningioma in a 25-year-old female with allergic bronchopulmonary aspergillosis (ABPA) caused by Aspergillus terreus. The patient presented with holocranial headache, diminished right eye vision, and other neurological symptoms. Radiological investigations revealed a right temporal space-occupying lesion with characteristic features of meningioma. The patient underwent right temporal craniotomy with tumour decompression. Histopathological examination confirmed the diagnosis of meningioma. This case highlights the importance of considering meningioma in the differential diagnosis of CNS lesions, even in patients with concurrent fungal disease in other organ systems. Additionally, it draws attention to Aspergillus terreus as a causative agent of ABPA, which is relatively uncommon compared to Aspergillus fumigatus.
