Student Case Presentation Nick Paphitis, SMD-06 University of Virginia Health System 55yo male • 11/06 – CC: several weeks of intermittent HA (worse in AM), worsening dysequilibrium and visual changes (1yr h/o clumsiness and falls, dx’d as migraines) – Denied vertigo, weakness, weight loss, some N/V – PMHx – HTN, lipids – FHX – sister w/ migraines, father w/ prostate CA, mom w/ breast CA – SHx – no tobacco, 1-2 drinks/night – Meds – HCTZ, Lipitor Hospital Course and Outcome • Admitted to Neuro, NSGY performed craniotomy w/ • • • • gross total resection of tumor Path - hypercellular glial neoplasm composed of hyperchromatic, pleomorphic astrocytes. Areas of palisading necrosis are identified, as are regions of geographic necrosis. Endothelial proliferation is abundant and mitotic figures are easily seen, favor astrocytoma, WHO Grade IV (GBM) Post-Op uncomplicated with good improvement of neurologic symptoms Rad Onc – 1/3 to 2/15 along w/ temozolomide, did well, weaned from steroids completely F/U MRI @ Duke sched. 3/1/06 Radiographic Features and DDx • Malignant astrocytomas are usually hypointense on T1- weighted images. These tumors typically enhance heterogeneously and serpiginously following contrast infusion. There may be areas of solid contrast enhancement within a more diffusely serpiginous pattern, or the lesion may show a totally solid pattern of enhancement. • The enhancing tumor can be distinguished from the surrounding hypointense signal of edema on T1weighted sequences. On T2-weighted sequences, the edema is hyperintense and cannot be distinguished from tumor. • Midline shift, necrosis, hemorrhage w/in mass • DDx – malignant astrocytoma, metastatic dz, PCNSL, MS, low-grade glioma/astrocytoma, abscess Reference: Up to Date Recurrence?
