Left frontal lobe glioblastoma multiforme masquerading as psychosis: A case report

Brain tumours often present with a variety of early subtle, non-specific symptoms. This can obscure an organic origin of the illness, which deters timely referral and management. We report a rare case of psychosis in a patient with a left frontal lobe tumour, preceded by 2 months of lethargy and word- finding difficulty with minimal neurological deficits, who was referred to our psychiatric unit from a primary care facility. Blood investigation findings including tumour marker levels were normal. Prompt neuroimaging revealed a left frontal lobe lesion with findings indicating a glioblastoma. The patient was subsequently referred to the neurosurgical team for surgical resection of the tumour. A high index of suspicion is paramount among atypical sociodemographic groups of patients with atypical psychiatric presentations. The primary care setting, which is often the first point of contact for patients, provides an avenue for early detection of such cases and timely referral to the appropriate healthcare system to ensure an optimal outcome.
