SAMANCI, Y. et al. Lung carcinoma metastasis presenting as a pineal region tumor. Neurocirugía [online]. 2011, vol.22, n.6, pp.579-582. ISSN 1130-1473.
The pineal region is an unusual site for brain metastasis and most metastatic pineal lesions are asymptomatic. A 53 year-old man presented with severe headache, limitation of upward gaze and diplopia. The patient's neurological examination was unremarkable. Magnetic resonance imaging (MRI) scans of the brain demonstrated a 1,5 x 2 cm well demarcated solitary mass in the pineal region with hydrocephalus. Surgery was performed and adenocarcinoma was diagnosed. A systemic investigation revealed adenocarcinoma of the lung as primary lesion. Although rare, metastatic tumor should be considered in the differential diagnosis of pineal region tumors.
