  2. 2. Glioblastoma multiforme is best described as a/an (A) anaplastic glioma frequent in the cerebral hemispheres (B) central nervous system tumor frequent in childhood (C) malignant tumor often seen in the cerebellum (D) rare tumor accounting for less than 10% of CNS tumors (E) tumor with an average survival rate of 10 years
  3. 3. A child presents with nausea and vomiting, a recent onset of ataxia, and a posterior fossa tumor. The most likely diagnosis is (A) craniopharyngioma (B) medulloblastoma (C) meningioma (D) neuroblastoma (E) pinealoma
  4. 4. Which neoplasms are more frequent in children than adults? (A) astrocytoma and oligodendroglioma (B) craniopharyngioma and glioblastoma (C) glioblastoma and schwannoma (D) hemangioblastoma and pituitary adenoma (E) medulloblastoma and ependymoma
  5. 5. The most frequent neoplasm of glial origin in adults is (A) cerebral astrocytoma (well-differentiated) (B) ependymoma (C) glioblastoma multiforme (D) medulloblastoma (E) oligodendroglioma
  6. 6. The most frequent site of glioblastoma multiforme is the (A) brain stem (B) cerebellum (C) cerebrum (D) hypothalamus (E) spinal cord
  7. 7. Which of the following tumors is composed of stratified squamous epithelium and cholesterol deposits and presents clinically with visual field defects? (A) craniopharyngioma (B) cystic astrocytoma (C) glioblastoma multiforme (D) medulloblastoma (E) pituitary adenoma
  8. 8. A 70-year-old man with a 4 month history of personality change, headaches, and right hemiparesis was found to have a solitary, well-circumscribed, focally hemorrhagic and necrotic mass in the left frontal lobe. The most likely diagnosis is (A) glioblastoma multiforme (B) hemangioblastoma (C) medulloblastoma (D) meningioma (E) oligodroglioma
  9. 9. A 12-year-old patient has signs, symptoms, and radiographic evidence of a calcifying supresellar mass. The most likely diagnosis is (A) craniopharyngioma (B) hemangioma (C) neurilemmoma (D) pituitary adenoma (E) retinoblastoma
  10. 10. The most common origin of brain metastases in adults is (A) breast carcinoma (B) bronchogenic carcinoma (C) colon carcinoma (D) malignant melanoma (E) prostatic carcinoma
  11. 11. A 15-year-old boy with no sexual maturation is found to have papilledema, an enlarged sella turcica and fine calcifications above the sella turcica on skull x-ray. The most likely diagnosis is (A) cranio-orbital aspergillosis (B) craniopharyngioma (C) meningioma (D) pituitary adenoma (E) tuberculous meningitis
  12. 12. Ependymomas of childhood most commonly arise in the (A) cerebellum (B) cerebrum (C) fourth ventricle (D) medulla (E) spinal cord
  13. 13. A 7-year-old girl developed nausea and vomiting. Diagnostic studies revealed a mass arising from the floor of the fourth ventricle, extending out the foramina of Luschka into the cerebellopontine angles. The mos likely diagnosis is (A) astrocytoma (B) ependymoma (C) glioblastoma multiforme (D) medulloblastoma (E) neuroblastoma
  14. 14. The mayor of a small community begins to repeat a word over and over. He later develops seizures and headaches. A CT scan demonstrates a large tumor in his cerebral hemisphere. Biopsy of the tumor is most likely to disclose which one of the following? (A) astrocytoma (B) ependymoma (C) gangliocytoma (D) medulloblastoma (E) oligodendroglioma
  15. 15. Eighteen months following posterior fossa surgery for a brain tumor, an 11-year-old child presents with evidence of spinal cord compression. What tumor type is the most likely cause? (A) cerebellar astrocytoma (B) craniopharyngioma (C) medulloblastoma (D) meningioma (E) schwannoma (neurilemmoma)
  16. 16. An 80-year-old man developed cerebral lymphoma. Staging procedures determined that this was limited to the brain. Immunohistochemical studies would confirm that this lymphoma is most likely (A) B-cell lymphoma (B) T-cell lymphoma (C) Hodgkin disease (D) plasma cell myeloma (E) Waldenstrom macroglobulinemia
