Figure 1. Neuroimaging studies. Left: Pathological diagnosis of this heterogeneously enhancing lesion was teratocarcinoma. Right: Two years following an extensive transbasal resection, no tumor recurrence is noted.

Figure 2. Neuroimaging studies. Left and Right: Representative images of invasive esthesioneuroblastoma. Even with aggressive management, it is often difficult to achieve a 2-year survival rate in these cases.

Figure 3. Neuroimaging studies.The invasive nature of esthesioneuroblastoma precludes long-term survival in advanced cases. Left and Right: In this rare exception, a 10-year malignancy-free survival rate was noted postoperatively.

Figure 4. Neuroimaging studies. Upper Left and Right: Chondrosarcomas can invade locally. Lower: Following an extensive transbasal approach for resection and postoperative radiotherapy, a 6-year survival rate without significant recurrence was demonstrated.

Figure 6. Neuroimaging studies. Upper Left, Upper Right, and Lower Left: Small cell ethmoid carcinomas are managed by administering a 20-Gy dose of radiation preoperatively following aggressive resection. Lower Right: Results after excision and radiotherapy. With this paradigm long-term survival is possible.
