An 86-year-old female with medical comorbidities including well-controlled type 2 diabetes (HbA1c 5.6 %) on oral therapy and glaucoma who presented with 2 weeks of right ear pain, right frontal headache and right facial pain just lateral to the nose. The patient also described painful extraocular movements (EOMs) on the right, decreased vision, and thick purulent drainage from the right nasal cavity. Vitals were normal with a blood pressure of 132/70, heart rate of 78, respiratory rate of 14, oxygen saturation of 97 % on room air, and temperature of 36.7 degrees Celsius. Examination was significant for hand motion vision, severely restricted right eye EOMs with ptosis, and excyclotorsion. Computerized tomography of the head and orbits demonstrated soft tissue thickening and indistinctness of fat in the region of the right optic canal and right orbital apex, possibly representing extension of paranasal inflammatory disease to an unusual bone defect in the right lateral wall of the right sphenoidal sinus (). Additionally, there was associated right anterior ethmoidal mucosal disease and complete opacification of the right maxillary antrum. Magnetic resonance imaging (MRI) of the brain without and with intravenous (IV) contrast showed right-sided paranasal sinus infection with transsphenoidal phlegmonous extension into the right orbital apex and cavernous sinus consistent with orbital apex syndrome (, ). Ophthalmology and otolaryngology (ENT) were consulted and performed a right endoscopy of the nasal cavities. This revealed purulence from the right middle meatus obstructing the view of the sphenoid. Nasal swab was sent for bacterial culture. Infectious disease was consulted who recommended IV vancomycin, cefepime, and metronidazole in addition to dexamethasone.\nThe patient underwent surgery on hospital day three. ENT completed a broad endoscopic sinus debridement including right total ethmoidectomy, frontal sinusotomy, sphenoidotomy, tissue biopsy, and washout of orbital apex with tissues sent for bacterial and fungal cultures. Tissue from the right naris and right ethmoid sinus grew methicillin-susceptible Staphylococcus aureus (MSSA). Initial pathology at frozen section examination revealed mixed acute and chronic inflammation at all biopsy sites. The patient’s antibiotics were narrowed to IV cefazolin on hospital day 5. On hospital day 6, one colony of Aspergillus fumigatus grew from a culture of the right orbital apex tissue. The pathology revealed fungal hyphae consistent with Aspergillus spp. and related molds, with tissue invasion in the orbital apex (, ). She was started on IV voriconazole. She was discharged to a skilled nursing facility after a 9-day hospital course with antimicrobials including oral cefdinir for a 4-week course and oral voriconazole with a planned treatment course of at least 12 weeks. At two-week follow-up with infectious disease, a repeat MRI brain showed worsening right ethmoid and sphenoid sinus fungal infection. Intravenous caspofungin was added to her regimen for a two-week course of therapy with clinical improvement. She underwent further debridement with rigid endoscopy at two, four, and six weeks after diagnosis with mostly crusted blood products and no evidence of necrotic tissue. Ophthalmologic exam ultimately demonstrated improvement in visual acuity to 20/50 with full EOMs.
A 50-year-old female was admitted with a paroxysmal boring pain in the left parietal and left frontal region for 9 months, accompanied by progressive vomiting and decreasing of visual acuity and proptosis in the left eye. Headache could be relieved by diclofenac sodium. Two months prior to presentation, her headache worsened extending to the whole left side of the face, accompanied by numbness. No light perception or reflex was detected in the left eye. Horizontal movement was limited in the left eye. Pre-operative CT showed a 29 × 20 mm isodense lesion with heterogeneously enhancement in the region of the left cavernous sinus, left orbital apex, left optic nerve canal, and sphenoid sinus. Bone destruction could be seen in the left wall of the sphenoid sinus. The optic nerve could not be distinguished from the lesion (Fig. a). MRI showed a 21 × 26 mm patchy lesion that was isointense on T1WI and hyperintense on T2WI in the left cavernous sinus region (Fig. b, c). Enhanced-MRI showed noticeable enhancement of the lesion. The lesion was closely related to the dura mater and extended to the sphenoid sinus and optic apex, partly surrounding the left internal carotid artery (Fig. d). MRA suggested stenosis in the cavernous segment of the left internal carotid artery and A1 segment of the left anterior cerebral artery. The patient underwent partial mass excision via a pterional craniotomy due to its close attachment to the ophthalmic branch and maxillary branch of the trigeminal nerve. The lesion was partly fibrotic and partly a milk-white viscous substance. A biopsy was performed immediately and histopathologic examination revealed Aspergillus species (Fig. e). The patient was administered voriconazole after surgery. Post-operative images indicated the resection of the mass (Fig. f). Examination after a follow-up of 15 months showed a complete resolution of the headache. Her vision of the left eye was not regained.
