This case report describes the role of contrast-enhanced computed tomography (CT) in diagnosing multifocal brown tumours of the mandible secondary to primary hyperparathyroidism. A 35-year-old male presented with painless jaw swellings. CT revealed extensive multiloculated lytic lesions involving multiple mandibular sites, with cortical thinning and focal breaches. Crucially, the scan also identified an incidental, well-circumscribed lesion inferior to the right thyroid lobe, suggestive of a parathyroid adenoma. Histopathology of a jaw lesion confirmed a brown tumour, and biochemistry showed severely elevated parathyroid hormone levels. This case underscores the value of comprehensive CT imaging in characterizing these lesions and identifying the underlying endocrine aetiology, thereby guiding appropriate management and preventing misdiagnosis.
