Docetaxel-Induced Interstitial Pneumonitis Detected on 68Ga-PSMA PET/CT.

68Ga-PSMA PET/CT is a commonly performed procedure in the staging of intermediate- and high-risk prostate cancer after biochemical recurrence. Uptake of 68Ga-PSMA in benign conditions is also reported in the literature. Docetaxel is the mainstay of treatment in high-volume hormone-sensitive prostate cancer and castration-resistant prostate cancer. The major treatment-emergent adverse drug reactions attributed to docetaxel include myelosuppression, alopecia, and asthenia. Interstitial pneumonitis is seen in less than 2% of docetaxel-treated patients. We present a case of metastatic castration-resistant prostate cancer, wherein docetaxel-induced interstitial pneumonitis was detected on 68Ga-PSMA PET/CT, after docetaxel treatment.
