Video: Radiation and Brain Tumors Part 3 – Brain Tumors and Outer Space, featuring Dr Sandeep Burma

Part 3 of a three-part series reviewing the effects of radiation on the brain. Join in on this grand finale as we review brain tumor development in a pilot who had logged many hours flying aircraft at high altitudes.  High altitude pilots at the edge of the Earth's protective atmospheric shield, and astronauts just beyond it,...

Video: Radiation and Brain Tumors, Part 2 – Cured of One Cancer Only to Develop Another

Part 2 of a three-part series reviewing the effects of radiation on the brain.  Radiation is commonly used to treat a wide variety of neoplastic conditions and often has great success, but sometimes the treatment can cause additional problems.   Join me on a narrated tour of radiation’s dark side in this review of radiation-induced brain...

Video: Normal Neuro Anatomy: Coronal Section of the Brain Through the Anterior Commissure

Take an anatomy tour through a coronal section of the normal brain at the level of the anterior commisure.  Join me as I review the major neuroanatomical structures of the normal brain, touching on structures that are important to normal functioning and also key players in certain disease processes.     https://youtu.be/lwF0AySb0c0

Cerebral Vascular Territories

The cerebral hemispheres are supplied with blood via three major arteries: the anterior, middle, and posterior cerebral arteries.  This coronal section through the frontal lobes shows hemorrhage involving the vascular territory of which of these three major cerebral arteries? Answer:  The cerebral hemispheres are supplied with blood via three major arteries: the anterior, middle, and posterior... Continue Reading →

Ice Cream and Imaging: Typical Appearance of Vestibular Schwannoma

Cranial nerve schwannomas most commonly arise from Schwann cells that myelinate the distal aspect of the vestibular division of the 8th cranial nerve. Vestibular schwannomas, sometimes referred to by the double misnomer "acoustic neuroma" (it is a double misnomer because they are not neuromas and they do not usually involve the acoustic division of cranial...

Classic Imaging: Cyst with an Enhancing Mural Nodule

For many years the only mechanism for observing gross pathologic features of CNS neoplasms was to examine brains extracted after death.  However, advancements in imaging technology now allow providers to observe typical gross neuropathological findings in the brains of living patients.  Some brain tumors have characteristic MRI findings, an example of which is a cyst...

Verocay Bodies in Schwannoma

Schwannomas are peripheral nerve sheath tumors that arise from cells that myelinate peripheral nerve axons called Schwann cells. A classic histologic finding in schwannomas are Verocay bodies (arrows), which consist of short palisades of tumor cell nuclei separated by eosinophilic anucleate bands of tumor cell processes.  Verocay bodies are often more prominent in schwannomas that arise in the setting of a...
