Two cases of muco-pyocele of the posterior nasal accessory sinuses were reported. The diagnostic procedure of the disease was considered with special reference to a clinical evaluation of "computed tomography". The following conclusions were drawn:1) Muco-pyocele of the posterior nasal accessory sinuses is one of the most clinically significant disease causing visual disturbances. An early establishment of both diagnosis and surgical treatment is of prime importance for a satisfactory results.2) Conventional ophthalmological examinations, plain sinus and skull films, tomograms of the region of the posterior nasal accessory sinuses and angiograms of the internal carotid artery and the orbital vessels may be useful for making differential diagnosis of that pathologic condition, though these may require considerable experiences.3) The computed tomographic scanning (CT) is very valuable in the investigation of the posterior paranasal and the surrounding lesions, since the CT scan is capable of demonstrating whether these lesions are arising from, or extending into the posterior nasal accessory sinuses. The CT scan may be helpful to identify muco-pyocele and to differentiate it from many other diseases such as hypophyseal tumor or orbital lesions on the basis of detailed findings.
