[Pott's puffy tumor, a rare complication of frontal sinusitis].

Port's puffy tumour (PPT), corresponding to frontal osteomyelitis causing erosion of the anterior wall of the frontal sinus and subperiosteal abscess, is a rare but serious complication of frontal sinusitis or trauma to the region. It can occur even despite the use of antibiotics and requires surgical drainage of the abscess, excision of pathological tissues and obliteration of the frontal sinus by various materials. It can rarely progress to life-threatening intracranial extension. Practitioners must be extremely cautious in the presence of clinical signs suggestive of Pott's puffy tumour. The aim of this article is to present a case of progressively evolving PPT in a patient of 28 years by frontal headaches that are aggravated by painful swelling front soft and fluctuating by palpation and that has fistulated at the right upper eyelid. CT scan of the face revealed the presence of a discontinuity bone at the anterior wall of the right frontal sinus. The treatment consisted of surgery and antibiotics. The patient remained asymptomatic after a decline of 18 months.
