Two Cases of Allergic Fungal Sinusitis with Differing Postoperative Course

Figure 5

Case 2 MRI findings. (a) Computed tomography (CT) image of the paranasal cavity (axial section). (b) CT image of the paranasal cavity (sagittal section). (c) CT image of the paranasal cavity (coronal section). Soft-tissue contrasts are evident in the left maxillary sinus, the left frontal sinus, the left ethmoid sinus, and both sphenoid sinuses, along with bone thinning at the lamina papyracea and the base of the skull (white arrow). (d) T1-weighted MRI of the paranasal cavity (coronal section). (e) T2-weighted MRI of the paranasal cavity (coronal section). The paranasal sinus mucosa and nasal mucosa show isosignal intensity in the T1-weighted images, high signal intensity in the T2-weighted images, and the most of the allergic mucin show none to low signal intensity. (f, g) CT images of the paranasal cavity after the surgery (coronal section). There is no apparent evidence indicating disease recurrence.
