“…Czechowski et al (15) more specifically described small lesions of low signal intensity on T1-and T2-weighted MR images in 16 of 20 patients with sinonasal fungus ball and suggested that these appearances resulted from metabolic products within the fungus ball (9,16). The small central hypointense foci represent the fungal balls, while the surrounding high-signal intensity foci represent the inflammatory process.…”

When there are no calcifications visible on the CT scan, a hyperattenuating fungal ball located in the central area of the sinus with mucosal thickening on enhanced CT scans is an important feature of a non-invasive sinonasal fungus ball. On MRI, a sinonasal fungus ball has typical features of a marked hypointense fungus ball with a hyperintense mucosal membrane in T2-weighted images. A contrast-enhanced CT scan or MRI provides sufficient information for the preoperative differentiation of a sinonasal fungus ball from other forms of sinusitis.

“…Changes of underlying bony structures may include osteoporosis, bony destruction, loss of cortical margin with bony erosion, punched-out lytic lesions, osteophyte formation, osteomyelitis, periosteal elevation, marrow infiltration, and coarse trabecular pattern, and bony expansion. 7 Czechowski et al 8 reviewed the imaging techniques in 20 histologically confirmed cases of mycetoma. Sixty percent of patients showed increased radionuclide uptake consistent with infection.…”

Mycetoma is a chronic infectious disease of either bacterial (actinomycetoma) or fungal (eumycetoma) origin and is rarely encountered in the United States. Infections are usually associated with trauma and implantation of the organism into the skin/soft tissue, but symptoms may not occur for some time after the infecting event. Classically, findings include a subcutaneous infection at the site of previous trauma with the development of draining sinuses extruding grains of the causative microorganism.

“…The different strains involved in human infection impart specific colors to the grains shed through the discharging sinuses [4][5][6][7][8], so this color is of diagnostic value in the identification of the etiologic agent. Definitive identification of the causative agent is based on clinical features and microbiological, histopathologic, and roentgenographic studies [9,14]. However, the fungal elements are fastidious and may be difficult to culture [15].…”
