Abstract
|
|
|
|
The pineal gland is an unusual site for brain metastasis, and a solitary pineal gland metastasis is rare. A 71-year-old man presented with dizziness, gait disturbance, and memory impairment. Brain computed tomography revealed a solitary hyperdense mass with central calcification in the pineal region and obstructive hydrocephalus. Brain magnetic resonance images showed a heterogeneously enhancing mass with intratumoral calcification and microcysts. Metastatic squamous cell carcinoma was diagnosed following an endoscopic biopsy. A systemic review revealed that the primary site of the carcinoma was the lung. Although rare, metastasis should be considered in the differential diagnosis of pineal region tumors, especially in elderly patients with a pineal tumor that presents unusual imaging findings.
