Summary: We report linear calcifications along the trajectories of previously implanted depth electrodes in 2 patients. A 20‐year‐old man and a 38‐year‐old woman with medically intractable complex partial seizures (CPS), underwent bilateral frontal and mesiotemporal depth electrode implantation as part of their epilepsy surgery workup. Brain computed tomography (CT) at that time was normal (except for cerebrellar atrophy in one case). One patient had a left anterotemporal lobectomy (ATL), and the other declined operation. Subsequent CT scans showed linear calcifications 1–2 cm long in the occipital lobes (unilateral in 1 and bilateral in the other) that followed the trajectories of the temporal depth electrodes. This finding remained unchanged at latest followup (2–2.5 years), and no new pathology has appeared on subsequent scans. No abnormalities of calcium metabolism were detected. Review of all available CT scans of our patients with a history of previous depth electrode implantation showed no additional similar cases. We believe this is the first report of intracerebral calcifications after depth electrode implantation.
