Computed tomography (C-) of patient 1. (A) Coronal. A 4.2 x 3.5 x 2.2-cm nasal mass extends from the left frontal sinus through the anterior ethmoid until the inferior turbinate; the left frontal sinusitis is also seen. (B) Axial. Mass that fully occupies the nasal cavity, causing right septal deviation.

CT of the sinus showed a bilaterally occluded airway, with a 2.8 x 1.5 x 1.6-cm mass substituting the left middle turbinate and causing remodeling of the medial wall of the left maxillary sinus and septal deviation to the right with impaction on the contralateral middle turbinate (Fig. 8, Table 1). Chronic pansinusitis and left otomastoiditis were also seen.

A computed tomography of patient 2. Large left polypoid mass eroding the medial and superior wall of the left orbit, touching the globe and extending into the sphenoid recess. Bilateral frontal, maxillary, and sphenoidal sinusitis, and right ethmoidal sinusitis are seen. The right middle turbinate is what is left from a previous partial turbinectomy.

A CT of the sinus revealed a large nasal mass with a thin bony outline laterally, which extended into the sphenoid recess and left orbit (Fig. 2, Table 1).
Patient 2. Magnetic resonance image, showing a 4.6 x 2.3 x 3.7-cm expansile lesion in the left frontal sinus, with well-defined lobulated contours and homogeneous T1 hypointensity and T2 hyperintensity, extending into the sphenoid and ethmoid sinuses, displacing the superior rectus, medial rectus, and superior oblique muscle, which allowed protrusion into the left orbit. Mucosal thickening was seen in all paranasal cavities, particularly in the right ethmoid and maxillary sinuses. The intracranial cavity seems unaffected.

An 86-year-old man with a history of nasal bone fracture, gastroesophageal reflux disease, and diabetes mellitus presented with a left nasal mass incidentally found on an MRI of the brain (Fig. 4, Table 1).
Patient 3. Computed tomography C+ depicts a 2.6 x 2.5 x 1.7-cm solid left nasal mass obliterating the middle meatus, destroying the middle turbinate, and invading the anterior ethmoid air cells. There is erosion of the left lamina papyracea, but no orbital invasion is seen.

A CT showed a solid, well-circumscribed lesion (2.6 x 2.5 x 1.7 cm) that seemed to erode the middle turbinate, obliterate the left middle meatus, extend into the ethmoid air cells, and erode the left lamina papyracea (Fig. 5, Table 1).

(A) Coronal view. (B) Axial view of a computed tomography of the sinus in patient 4, which depicts a massive 5.2 x 5.5 x 3.5-cm well-defined bony mass with cortical remodeling, extending to the frontoethmoidal regions. A severe mass effect is seen: there is lateral bowing of the right maxillary sinus, left septal deviation, and elevation of the right fovea ethmoidalis. There was no significant enhancement with contrast. All right-sided sinuses were opacified.

A CT confirmed a bony mass in the right nasal cavity that was causing significant mass effect toward the left and obliteration of the frontal, ethmoid, and maxillary sinuses (Fig. 6, Table 1).
Patient 4. Magnetic resonance image, (A) T1, (B) T2, showing a large expansile lesion in the right nasal cavity (5.4 x 6.1 x 3.6 cm) extending into the frontoethmoid recess, remodeling of the medial wall of the right maxillary sinus with lateral bowing, and severe nasal septum deviation. There was a T1 hyperintensity and T2 hypointense signal intensity without enhancement and a rim of high T2 signal associated with linear enhancement. Right frontal, ethmoid, and maxillary sinuses are opacified, the right maxillary with inspissated secretions.

MRI confirmed the massive nasal mass (5.4 x 6.1 x 3.6 cm), which led to a differential diagnosis of CBM, fungus ball, or Wegener granulomatosis (Fig. 7, Table 1). Middle turbinate cultures isolated Staphylococcus aureus and Haemophilus influenzae organisms.
