Intracerebral Hemorrhage - Erler Zimmer 3D anatomy Series MP2012

This dissection model highlighting an Intracerebral Hemorrhage is part of the exclusive Monash 3D anatomy series, a comprehensive series of human dissections reproduced with ultra-high resolution color 3D printing.

Clinical History.

The patient was an 80-year-old man who suddenly lost consciousness. On examination there was right gaze palsy, left hemiplegia, and right hemiparesis.

Pathology

The specimens are coronal sections of the brain at the level of the mammillary bodies (specimen where the cut surface of the brain stem is visible where the cerebral peduncles and sustantia nigra are also visible) and more anteriorly where part of both temporal lobes are included. A huge blood clot replaced brain tissue in the region of the left basal ganglia and internal capsule. The hemorrhage originated in this area and ruptured into the left lateral ventricle and its temporal horn, destroying the walls of the left lateral ventricle and extending into adjacent brain tissue. The right lateral ventricle is also filled with blood, but its walls are intact. The blood clot forms a space-occupying lesion that has enlarged the left cerebral hemisphere, causing the midline structures to shift to the right.

Note

Intracerebral hemorrhages of this type are usually a complication of systemic hypertension. The hemorrhage occurs by rupture of a microaneurysm of a branch of the striated arteries, which originate from the middle cerebral artery and supply the basal ganglia.

What advantages does the Monash University anatomical dissection collection offer over plastic models or plastinated human specimens?

• Each body replica has been carefully created from selected patient X-ray data or human cadaver specimens selected by a highly trained team of anatomists at the Monash University Center for Human Anatomy Education to illustrate a range of clinically important areas of anatomy with a quality and fidelity that cannot be achieved with conventional anatomical models-this is real anatomy, not stylized anatomy.
• Each body replica has been rigorously checked by a team of highly trained anatomists at the Center for Human Anatomy Education, Monash University, to ensure the anatomical accuracy of the final product.
• The body replicas are not real human tissue and therefore not subject to any barriers of transportation, import, or use in educational facilities that do not hold an anatomy license. The Monash 3D Anatomy dissection series avoids these and other ethical issues that are raised when dealing with plastinated human remains.
