“…Computed tomography (CT) of the sinuses is the first choice for preoperative diagnosis of chronic rhinosinusitis and for planning ESS because of its ability to delineate the fine bone structures of the sinuses, orbital lamina, and skull base . Several studies have reported the CT features of MSFB, which include intralesional hyperdensity (IH), calcification spots, erosion of the inner sinus wall, irregular surface of the material, and sclerosis of the lateral sinus wall …”

Objectives/Hypothesis Maxillary sinus fungus ball (MSFB) is the most common type of noninvasive fungal rhinosinusitis. Surgical removal of the ball achieves good outcomes. Making a rapid and accurate diagnosis is important to avoid unnecessary medical therapy. Intralesional hyperdensity (IH) on computed tomography (CT) is reportedly a good indicator. The aim of this study was to evaluate the diagnostic features of MSFB without IH on preoperative CT images. Study Design Retrospective database review. Methods Two hundred fifty‐eight patients with histopathological evidence of a sinus fungal ball were retrospectively investigated. Forty‐seven of 222 patients with MSFB did not show IH on preoperative CT images and were enrolled in the MSFB group. Forty‐one patients with unilateral nonfungal chronic rhinosinusitis were enrolled in a control group. CT features previously reported to have diagnostic significance were evaluated. Results Sclerosis of the lateral sinus wall, erosion of the inner sinus wall, and irregular surface of the material were significantly more common in the MSFB group than in the control group. In the subgroup of patients with total opacification in the maxillary sinus, the sensitivity, specificity, and positive and negative predictive values for erosion of the inner sinus wall were more than 90%. In the subgroup with partial opacification, the sensitivity, specificity, and positive predictive value of an irregular surface of the material were more than 80%. Conclusions We have devised an algorithm to help diagnose MSFB without IH on preoperative CT images. Use of this algorithm would improve the diagnostic accuracy and ensure appropriate treatment.

“…In a previoius study (13), the prevalence of intrasinus calcifications on CT scans in patients with sinonasal fungus ball has been reported as 67.2% (116 cases). The calcifications were located mostly in the center of the maxillary sinus (85.9%), followed by near the sinus wall (7.7%).…”

Cone Beam Computed Tomographic Findings of Double Osteomas with Maxillary Sinusitis

An osteoma may originate from cartilage or embryonal periosteum. It may occur externally or within the paranasal sinuses. In most cases, a paranasal osteoma is a solitary lesion and is located in a single sinus. A double osteoma with maxillary sinusitis is rare. A 54-year-old woman was referred for evaluation and treatment of a right maxillary sinus bony lesion. She complained of headache and foul smell after sneezing since 1 month ago. Panoramic radiography revealed two radiopaque masses in the right maxillary sinus. Cone beam computerized tomography images revealed radiopacities with partially corticated borders attached to the medial wall of the right maxillary sinus, near-complete radiopacification of the right maxillary sinus, and peripheral bony thickening due to chronic sinusitis. On histopathologic examination, the removed radiopaque masses were diagnosed as osteomas.

Computed tomography (CT) is often the primary imaging modality for the evaluation of sinonasal disease. For some indications, magnetic resonance imaging (MRI) may provide additional information. There are established indications for using MRI in complicated sinonasal inflammatory disease, invasive fungal sinus disease, and sinonasal mass lesions. When MRI is used in the evaluation of sinonasal disease, it is usually used as a complementary modality in addition to CT. Magnetic resonance imaging in sinonasal disease can be used to further characterize the primary sinonasal disease process and to evaluate the extent of complications such as orbital or intracranial involvement. When MRI is used in sinonasal disease, it should be evaluated in the context of the clinical situation and CT imaging features. This will help radiologists provide a meaningful differential diagnosis to assist in clinical management.
