Pineal metastasis is uncommon and most metastatic pineal lesions are asymptomatic. To our knowledge the herein reported case is the first in which the pineal gland was confirmed as the metastatic site of a bladder carcinoma.
The patient reported in this case is a 59-year-old man who suffered from headache and delirium for 4 days after surgical treatment for removal of a bladder carcinoma 1 year ago. Magnetic resonance imaging (MRI) revealed a solid tumor involving the pineal gland with significant enhancement.
The patient underwent surgical treatment for removal of the neoplastic lesion in the pineal gland. Histopathological examination confirmed invasion of the pineal gland by metastatic urothelial carcinoma.
This case highlighted that the presence of pineal lesions in patient with known malignancy should raise suspicion of metastatic involvement.
