    • Melanoma

    • Sarcomas

    • Breast CA

    • Colon CA

    Correct Answer

    What indicates the best prognosis for Ependyomas?

    • Astrocytomas

    • Anaplastic Astrocytomas

    • Gliomas

    Correct Answer
    A. Astrocytomas
    Explanation
    this is a low grade glioma which will offer the best prognosis: Anaplastic Astrocytomas are Grade 2 and Gliomas are grade 3

  • 5. 

    What location is most severely affected in patients with meningiomas?

    • Tentorium Cerebelli

    • Transverse Sagittal Sinus

    • Confluence Point

    • Falx Regions

    Correct Answer
    A. Falx Regions
    Explanation
    Meningiomas are tumors that occur in the meninges, the protective membranes surrounding the brain and spinal cord. The falx cerebri is a fold of the dura mater that separates the two cerebral hemispheres. It runs along the midline of the brain. When meningiomas develop in the falx regions, they can cause severe effects due to their location and potential compression of brain tissue. Therefore, the falx regions are the most severely affected location in patients with meningiomas.

    Rate this question:

  • 6. 

    What is histologically representative of meningiomas?

    • Malignancy

    • Hypercellularities

    • Rosettes

    • Swirls

    • Whirls

    Correct Answer
    A. Whirls
    Explanation
    Whirls are histologically representative of meningiomas. Meningiomas are typically characterized by the presence of whorls, which are concentric arrangements of tumor cells. These whorls can be seen under a microscope and are a key feature used to diagnose meningiomas. Other histological features commonly associated with meningiomas include hypercellularities, rosettes, and swirls. However, the presence of whirls is the most specific and characteristic feature of meningiomas.

  • 7. 

    Where does ependymomas occur in the spinal cord?

    • Ventral horn

    • Cauda qquina

    • Filum terminale

    • Conus medullaris

    Correct Answer
    A. Filum terminale
    Explanation
    Ependymomas occur in the filum terminale of the spinal cord. The filum terminale is a slender strand of connective tissue that extends from the conus medullaris to the coccyx. Ependymomas are tumors that arise from the ependymal cells lining the central canal of the spinal cord. They are typically slow-growing and can cause symptoms such as back pain, weakness, and sensory changes. Treatment usually involves surgical removal of the tumor, sometimes followed by radiation therapy or chemotherapy.

    Rate this question:

  • 8. 

    Primary CNS lymphomas occurs predominantly in whom?

    • AIDS patients

    • Children with DiGeorge Syndrome

    • people with Tap defiencies in MHC class I

    • Some with Bruton's Tyrosine Kinase Defiency

    Correct Answer(s)
    A. AIDS patients
    A. Children with DiGeorge Syndrome
    Explanation
    In a AIDS pts. the CD-4 is below 200 mm/cm3, and in a patient with DiGeorge syndrome the Thymus is nonfunctional or absent making them extremely immunocompromised. In people with MHC I defiencies of Tap this is not as severe because this is part of the adaptive immune system, and so is Bruton Tyrosine Kinase (B-Cells).

    • Corticospinal

    • Urinary retention

    • Spinothalamic

    • Scoliosis

    • Lordosis

    Correct Answer(s)
    A. Corticospinal
    A. Urinary retention
    A. Spinothalamic
    Explanation
    also a possible sx is back pain

    • Decadron

    • Methotrexate-anti cancer drug

    • Radiation therapy

    • Surgery

    Correct Answer
    A. Decadron
    Explanation
