The median anterior and central skull base forms an interface between the sinonasal and intracranial compartments. Due to the proximity of the intracranial structures, skull base involvement is a key…
The neoplastic lesions that can be found in the sinonasal space are numerous and varied. This article describes a general approach to narrowing down the differential diagnosis and provides the…
Endoscopic sinus surgery is a minimally invasive option for the treatment of several nonneoplastic indications, particularly for medically refractory sinusitis and polyposis. Numerous interventions can be performed through endoscopic sinus…
This article describes the computed tomography and MR imaging features of the neoplasms of the sinonasal space. Although a pathologic diagnosis may not always be possible, knowledge of the features…
The aim of imaging in the follow-up of asymptomatic patients treated for sinonasal neoplasms is to detect submucosal relapsing lesions. The challenge is to discriminate recurrent tissue within the changes…
While most patients with inflammatory rhinosinusitis are successfully diagnosed clinically, imaging is indicated in patients with recurrent or chronic sinusitis, atypical symptoms and complicated acute sinusitis. Non-enhanced high resolution, thin…

Fungal sinusitis is characterized into invasive and noninvasive forms. The invasive variety is further classified into acute, chronic and granulomatous forms; and the noninvasive variety into fungus ball and allergic…
It is imperative for all imaging specialists to be familiar with detailed multiplanar CT anatomy of the paranasal sinuses and adjacent structures. This article reviews the radiologically relevant embryology of…
As endoscopic sinus surgery (ESS) has evolved since its introduction to the United States, so has technology for imaging the sinonasal cavities. Although imaging is most frequently performed for evaluating…
