Metastasis of prostate carcinoma to the thyroid cartilage presenting with airway obstruction

Two-year follow-up of a thyroid cartilage metastasis from prostate cancer: A case report

“…Accordingly, radiotherapy was recommended [15] . As per a recent report, such lesions can significantly grow to then potentially compromise the airway [17] . Similarly, our patient was diagnosed with metastatic castrate-resistant prostate cancer.…”

“…In these instances - as with all oncologic decisions - the patient's overall status is a key determinant. In case of obstruction, ensuring a patent airway is first and foremost [17] . In case of a symptomatic lesion, palliative treatment shall be attempted.…”

Prostate-Specific Membrane Antigen PET/CT Detection of Prostate Cancer Metastasis to Thyroid and Cricoid Cartilages

“…4 Of the previously reported cases, most were detected using the 68 Ga-PSMA PET/CT; however, some reports have also used conventional CT imaging, MRI, and 18 F-fluorocholine PET/CT modalities. [5][6][7][8][9][10] Here, we present 4 patients with metastatic lesions to thyroid and cricoid cartilages detected on PSMA PET/CT at our institution over the span of 19 months. This limited data set suggests that the incidence of prostate cancer metastasis to the thyroid and cricoid cartilages may be far more common than previously presumed.…”

“…As metastases typically spread through the bloodstream and lymphatic system, metastatic lesions are unlikely to be found in such tissue 4. Of the previously reported cases, most were detected using the 68 Ga-PSMA PET/CT; however, some reports have also used conventional CT imaging, MRI, and 18 F-fluorocholine PET/CT modalities [5][6][7][8][9][10].
