  • Title: Lesson of the month: Cytotoxic lesions of the corpus callosum (CLOCCs) in status epilepticus.
    Author: Abdulghani M, Das S, Manfredonia F.
    Journal: Clin Med (Lond); 2022 Sep; 22(5):493-495. PubMed ID: 36507823.
    Abstract:
    A 26-year-old man was diagnosed with epilepsy a few months previously and admitted with status epilepticus. Computed tomography (CT) of the brain and CT venography were unremarkable. Magnetic resonance imaging (MRI) of the brain showed evidence of possible acute focal infarction in the splenium of the corpus callosum that showed a true restricted diffusion. The patient had no vascular risk factors and no focal neurological deficit on examination to explain the occurrence of an acute infarction. MRI of the brain was repeated 1 month later to assess for progression of that lesion and showed resolution of it. This case highlights the association of cytotoxic lesions of the corpus callosum that show true restricted diffusion with status epilepticus. It also emphasises the importance of medical reasoning and not being solely dependent on diagnostic investigations without reasonably linking them to the history and examination.
