Purpose:
We present a case of metastatic neoplasia in the right frontal sinus derived from and hypernephroma, with a clinical picture that initially was interpreted as a mucocele.
Patients And Methods:
Sixty years old male. Personal history: prostatectomy and left nephrectomy because of hypernephroma three years before. In december 92 the patient reported a protrusion in the right frontal sinus. CT scans and NMR revealed a breakage of the external and internal walls of the right frontal sinus and the right orbital roof. In february 93 a surgical exploration of the frontal sinus revealed the metastatic nature of the lesion.
Discussion:
Metastatic tumors in paranasal sinuses are infrequent since most of the tumors in this localization are primary. Metastatic affectation of the frontal sinus is extremely rare. We recommend the systematic exploration of paranasal sinuses in patients affected by hypernephroma.
