Our patient is a 15 year-old boy, with a previous diagnosis of neurofibromatosis type 2, who had undergone surgical resections of olfactory groove tumors, at five and 13 years of age. Both resections had histopathologically-confirmed meningothelial meningioma (WHO grade I). The patient also had other intracranial lesions bilaterally in the cerebellopontine angle, and in the left Mackel cave, involving the vestibular and trigeminal nerves. All of these lesions showed enhancement with MRI. The patient suffered left hearing loss and left hemiparesis since the first surgery 10 years ago. Three months before admission, the patient developed seizures and antiepileptic drugs were introduced. MRI showed relapse in the olfactory groove lesion (Figure 1a). At this time, a third microsurgical approach of the olfactory groove lesion was performed, achieving satisfactory resection (Figure 1b). The patient’s condition did not worsen postoperatively.
