A 47-year-old man with a history of macrocephaly was diagnosed with spontaneous non-traumatic bilateral calcified subdural hematomas (SDHs) ( Figures 1 – 2 ). He had chronic, daily, bilateral, dull headaches for many years. His head circumference was 62 cm, but his neurological examination was unremarkable. Calcified chronic SDHs are an unusual entity and a rare complication of chronic shunting for hydrocephalus 11. Petraglia AL, Moravan MJ, Jahromi BS. Armored brain: a case report and review of the literature. Surg Neurol Int 2011;2:120. . Although not previously diagnosed, we suspect he may have suffered from arrested hydrocephalus. Due to his increased head circumference, stretching of bridging subdural veins may have developed, slowly enlarging the bilateral SDHs, which later became calcified. The encased appearance of the brain with bilateral and extensive chronic calcified SDHs is described as the “armored brain,” also known as “matryoshka head” after the famous Russian nesting dolls 22.

Ossified chronic subdural hematoma with armored brain. Turkish Neurosurg 2008;18:420-424. . Our observation is unique because our patient never underwent a shunting procedure.
