Abstract
A 62-year-old man was referred for a 68Ga–prostate-specific membrane antigen (PSMA) PET/CT scan for newly diagnosed prostate cancer (ISUP grade 5), on the background of left vestibular schwannoma treated with surgical excision 25 years ago. PSMA PET study confirmed the presence of PSMA-avid malignancy in the left prostate lobe with no evidence of PSMA-avid nodal or distant metastasis. An incidental PSMA-avid focus (SUVmax, 4.3) was identified in the region of the left cerebellopontine angle, which corresponded to a homogeneous enhancing lesion centered at the left internal acoustic canal and left cerebellopontine angle on MRI. The combined PSMA PET findings and MRI characteristics were consistent with recurrent vestibular schwannoma.
