Preoperative cerebral CT showed a new local hypermetabolic foci in the left frontal lobe (A). Postoperative cerebral CT showed the tumor was completely resected (B). CT = computed tomography.

Cerebral CT, MRI, and positron emission tomography-CT showed that there was a new local hypermetabolic foci in her left frontal lobe, which was very likely to be an ectopic recurrence (Fig. 1A). The tumor underneath the galea aponeurotica adjacent to the cerebral falx in the left frontal lobe was completely resected (Fig. 1B).
The postoperative pathology examination results were consistent with the diagnosis of MPNST. H&E x 100 (A) S100 x 100 (B) NF x 100 (C) NSE x 100 (D); Ki-67 x 100 (E). Scale bar: 20 mum. MPNST = malignant peripheral nerve sheath tumor.

The postoperative pathology examination (Fig. 2) showed that most of the cells were malignant spindle cells.
