3D Printed Intracranial Space-Occupying Lesion

3D Printed Intracranial Space-Occupying Lesion Clinical HistoryA 56-year-old woman with 6 months of intermittent headache and vomiting was admitted to hospital comatose after a grand mal seizure, and failed to regain consciousness. PathologyThe specimen is a coronal section of a brain. It is evident that the brain has been compressed laterally and downwards by a right-sided expanding intracranial mass, probably a meningioma. The original mass is not present. The anterior face shows shift of midline structures with subfalcine herniation* of the cingulate gyrus. The posterior face (see photo) shows haemorrhage of varying ages within the temporal lobe and the pons, typical of supratentorial mass lesions. There is also ventricular asymmetry. *In subfalcine (or cingulate) herniation, the most common type of brain herniation, the innermost part of the frontal lobe is pushed under part of the falx cerebri, between the two hemispheres of the brain.
