Summary A 59-year-old woman suffered from occipital headache and bilateral cranial nerve VII, VIII, IX, X, XI and right XII deficit after developing otitis media. Magnetic resonance imaging (MRI) showed a thickening of the dura mater which was enhanced by gadolinium-DTPA (Gd). Aspergiflusflavus was identified from the culture of otorrhea. She was treated with miconazole, flucytosin and fluconazole, which resulted in an improvement of the clinical symptoms and a thinning of the Gd-enhanced lesions on MRI. This is the first case of hypertrophic cranial pachymeningitis caused by Asp. j?avus infection.
Introduction
Case report
Hypertrophic cranial pachymeningitis is a rare disease that often causes multiple cranial neuropathy. By now, few cases have been reported in the literature, and the greater part of them are still etiologically unclarified. We report a case of hypertrophic cranial pachymeningitis following otitis media, presenting occipital headache and multiple cranial neuropathy. AspergiZlus fIavus was proven to be the etiological agent. To our knowledge, this is the first case of hypertrophic cranial pachymeningitis due to Asp. fzavus infection.
A 59-year-old woman was born deaf in her left ear due to Mondini’s anomaly (hypoplasia of the auris interna). She had suffered from diabetes mellitus since 1968, and has been receiving insulin therapy for the past 2 years. In addition, she developed liver cirrhosis with esophageal varices in 1986. In October 1987, she developed otitis media on the left side. She noticed left occipitalgia a few months later, and developed left facial palsy in April 1988. In October 1988, she noted hoarseness and difficulty in swallowing. In January 1989, she suffered from otitis media on the right side, followed by headache and hearing impai~ent on the right side. In March 1989, a tracheal fenestration was performed as she developed dyspnea because of palsy of the bilateral vocal cords. On April 3, 1989, the date of the admission to our department, physical examination revealed: anemic palpebral conjunctivae and hepatomegaly (4 cm palpable below costal margin). Mental state was normal, and cranial

Gait was slightly unsteady; tandem gait was poor. Mild impairment of vibratory sensation and hyporeflexia, symptoms of diabetic neuropathy, were observed in the lower extremities. The blood count showed mild anemia (Hb 10.2 g/dl). The ESR was 55 mm/h. Serum protein was 8.0 mgldl and albumin 3.3 mg/dl. Liver function tests were: GOT 52 IU/l. y-GTP 204 IUIl, cholinesterase 68 IUIl, and ICG 43.8% (15 min). The fasting glucose level was 163 mgidl and HbAlc level was as high as 7.0%. C-reactive protein level was 1.5 mg/dl (normal, < 0.4 mgidl). The cerebrospinal fluid was clear. showing mild pleocytosis (7/mm’) and 66 mgidl protein.

Fungal hyphae were microscopically observed in the smear of the surgically evacuated content in the right maxillary sinus. A culture of the otorrhea revealed the formation of yellowish green colonies, which were identified as Asprl-giffus,fl~us (Fig. 2). From May 16, miconazole therapy was started with an initial dose of 200 mgiday up to 1000 mg/day, intravenously. One month later, occipital headache, bilateral facial palsy and dysphagia improved markedly. Furthermore. an MRI taken on June 28 revealed that the Gd enhancement of the dura mater in the posterior fossa was markedly reduced (Fig. 1b). Miconazole was discontinued 1 month later because of the worsening anemia. Flucytosine (4 6 g/day) and then. fluconazole (100 mgi day) was administered orally instead.

Discussion In the present case, a marked thickening of the dura mater in the posterior fossa as seen on MRI, indicated hypertrophic cranial pachymeningitis to be the cause of multiple cranial neuropathy. We assumed Aspergihs to be the etiological agent because of the following reasons, although we have not performed any surgical exploration of the dura mater: (1) fungal hyphae were observed in the content of the maxillary sinus, and Asp.
