We report the case of a patient with organized chronic subdural hematoma (OCSH) that was treated with craniotomy. A 72-year-old man was admitted with a complaint of a drowsy mental status after a generalized tonic-clonic seizure. A brain computed tomography scan acquired at a local hospital revealed a large chronic subdural hematoma (CSDH) in the left frontoparietal lobe. The patient had not experienced head trauma and had been taking clopidogrel due to angina. A neurosurgeon at the local hospital performed single burr hole trephination in the left frontal bone and drained some of the hematoma. Brain magnetic resonance imaging performed upon transfer to our hospital showed a large OCSH with a midline shift to the right side, revealing a low, heterogeneous signal on T2-weighted images (WI) and an isodense signal on T1-WI. We performed craniotomy and membranectomy to achieve adequate decompression and expansion of the brain. Following this, the patient recovered completely. Our findings support that neurosurgeons should consider the possibility of organization of a CSDH when selecting a diagnosis and treatment plan.
