case_images: Necrotic brain tissue was evident at the point of entry of the retained short arm of the spanner [Figure 1a]. T-shaped spanner penetrating the left parieto-occipital lobe of the brain, extending into the contralateral occipital lobe [Figure 1b]. The situation was explained to the attendants and the patient was brought to the operating room with the retained spanner approximately 3 hours after admission and the intervention was designated as high risk. The intracranial part of the metallic spanner was slowly removed followed by debridement and irrigation of the track with normal saline and hydrogen peroxide [Figure 1c-e].
