Question

A patient is admitted to the hospital and found to have a tumor near the cerebral aqueduct, which is causing cerebrospinal fluid (CSF) to accumulate in the brain. The patient is subsequently diagnosed with

A) Meningioma
B) Glioblastoma multiforme
C) Ependymoma
D) Acoustic neuroma

Answer 1

A patient with a tumor causing CSF accumulation near the cerebral aqueduct would likely be diagnosed with an Ependymoma, a type of tumor that can lead to hydrocephalus, or excess CSF buildup causing pressure against the skull.

Step-by-step explanation:

A patient admitted to the hospital with a tumor near the cerebral aqueduct leading to an accumulation of cerebrospinal fluid (CSF) would likely be diagnosed with an Ependymoma. This type of tumor arises from ependymal cells that line the ventricular system of the brain, which is where CSF is produced. The accumulation of CSF, known as hydrocephalus, occurs when the flow of CSF is blocked, leading to its buildup and resulting in pressure against the skull. Symptoms can include seizures, cognitive issues, and without treatment, could potentially lead to death. A treatment option includes the insertion of a shunt to drain the excess CSF and alleviate pressure.
