FIG. 1 — Case 1. Preoperative axial noncontrast CT (A) and axial (B) and coronal (C) contrast-enhanced T1-weighted MRI showing a large, enhancing anterior skull base lesion. Postoperative axial noncontrast CT (D) and axial (E) and coronal (F) contrast-enhanced T1-weighted MRI following staged EEA and left-sided orbitozygomatic craniotomy with STR of the lesion. Postoperative axial noncontrast CT (G) and axial (H) and coronal (I) contrast-enhanced T1-weighted MRI showing recurrence of the anterior skull base tumor. Axial noncontrast CT (J) and axial (K) and coronal (L) contrast-enhanced T1-weighted MRI following combined EEA followed by a right-sided frontal orbital temporal craniotomy for NTR of the lesion. Axial noncontrast CT (M) and axial (N) and coronal (O) contrast-enhanced T1-weighted MRI 28 months after the second surgery (36 months after the index surgery).
