Overview
- What this deck will teach you
The Tumors
What actually grows inside the lateral ventricles
- Why lateral ventricular tumors are a special problem
- How these tumors make themselves known
- Age plus location narrows the diagnosis
- Gliomas: the common adult primary tumors
- Oligodendroglioma extending into the ventricles
- Ependymomas, subependymomas, and how to tell them apart
- Giant cell astrocytoma at the foramen of Monro
- Meningiomas: second most common, favor the atrium
- Meningioma of the right atrium
- Choroid plexus tumors: the pediatric-leaning group
- Choroid plexus papilloma filling the left atrium
- Central neurocytoma and the incidental cysts
- Central neurocytoma arising from the septum pellucidum
- Tumors from elsewhere: metastases and lymphoma
- Metastatic tumor in the right atrium
- Primary CNS lymphoma extending into the frontal horn
- Quick reference: tumor, favored location, and age clue
The Anatomy
The C-shaped cavity and its five parts
- The big picture: a paired C-shaped cavity
- The frontal horn: the front tip
- The body: the long middle segment
- The atrium: the busy crossroads
- The occipital and temporal horns
- Landmark table: which structure forms which wall
Blood Supply and Drainage
The arteries that feed and veins that empty the ventricle
- Arterial supply: two choroidal systems that meet
- Choroidal artery territories by region
- Venous drainage: everything funnels to the deep veins
Planning the Operation
Selecting patients and mapping the brain before surgery
- Who gets surgery, and who gets a biopsy
- Mapping the brain before you cut: functional imaging
- Mapping the blood supply and using real-time tools
The Operative Approaches
Choosing and performing a corridor to the tumor
- General principles: the corridor follows the location
- Choosing the corridor from tumor location
- Transcallosal approach: getting in through the midline
- Transcallosal approach: the dissection and entry
- Transcallosal approach: staying oriented inside
- Posterior transcallosal and precuneal variations
- Transcortical approach: a direct cortical route
- BrainPath resection of a right atrial meningioma
- Anterior and posterior transcortical routes
- DTI tractography around a right atrial meningioma
- Temporal-horn approaches: sparing language and vision
- The transsylvian approach to the temporal horn
After Surgery
Recovery, imaging, and the guiding principles
- Postoperative management
- Three ideas to carry away
- Viva: A tumor sits in the medial atrium. Which corridor, and what one preoperative finding would change your mind?
