Practice Based Learning and Systems Based Practice
  1. Gain an understanding of the utility of cytopathology evaluation of central nervous system (CNS) lesions
  2. Appreciate the importance of a multidisciplinary approach to diagnosis
    1. Anatomic location of lesion within CNS
    2. Clinical history and presenting signs and symptoms
    3. Radiologic imaging characteristics
  3. Appreciate the diagnostic utility of stereotactic guided needle biopsy of CNS lesions, given the procedure's low morbidity and mortality
    1. Recognize the ability of core needle biopsy to accurately distinguish reactive / inflammatory conditions from neoplastic lesions
    2. Learn basic technical aspects of stereotactic guided needle biopsy
    3. Appreciate the utility of immediate, onsite cytopathologic evaluation of tissue obtained (interpersonal comunication)
    4. Understand proper preparation techniques for immediate cytologic evaluation in order to allow accurate diagnosis while preserving tissue for additional studies (smear techniques, use of appropriate stains)
    5. Understand proper triaging of specimen based upon initial morphologic impression
Medical Knowledge
  1. Gain familiarity with the morphologic appearance of normal brain tissue in cytology preparations and stains
    1. Astrocytes (including reactive astrocytes), oligodendrocytes, normal neuronal cells, choroid plexus, etc.
