Metástasis no osteoblástica rinosinusal y orbitaria por adenocarcinoma de próstata

Background

Bone metastases due to prostate adenocarcinoma usually present osteoblastic characteristics on the imaging modalities.

Method

Case report.

Results

A 77-year-old patient diagnosed with prostate adenocarcinoma with osteoblastic metastases in the dorsal spine and ribs, empirically treated with decongestants for symptoms associated with nasal polyposis, presented with binocular diplopia and ptosis of the right eyelid. Painful ophthalmoplegia and ipsilateral frozen orbit were observed. The CT confirmed the presence of a soft tissue density neoformation infiltrating the paranasal sinuses spreading towards to the base of the skull and extraocular muscles. Biopsy by endoscopic sinus surgery triggered the diagnosis of metastasis.

Conclusions

Regardless of the characteristics seen on the imaging modalities, onset in other organs and systems in patients with a history of prostate adenocarcinoma should prompt the histopathological study of the lesions.
