Invasive aspergillosis usually does not occur in immunocompetent patients. Recently, however, the incidence of invasive aspergillosis has been increasing in immunologically competent patients. It is difficult to diagnose neuroaspergillosis because of its varied radiological findings and clinical manifestations. We report a case of aspergillosis of the central nervous system, presenting as a mass-like lesion, in an immunocompetent patient. The patient was diagnosed after a surgical biopsy and treated with antifungal agents. The clinical outcome was good.

Aspergillosis of the central nervous system from sinonasal origin is rare in immunocompetent hosts. Due to the rarity of the cases in immunocompetent hosts, only few cases are reported in the previous literature. But, some cases reported diversity of clinical presentations in immunocompetent hosts. Aspergillosis of the central nervous system from sinonasal origin, bony invasion with only orbit or cranial base was more common than intracerebral aspergillosis in immunocompetent hosts. In this type of disease, although maxillary sinus is more commonly involved, sphenoid sinus and clivus are unusual sites for aspergillosis of central nervous system. Because of the anatomical position of sphenoid sinus, it is associated with poor prognosis with intracranial extension. We reported a case of the aspergillosis of central nervous system involving clivus in the immunocompetent host who was misdiagnosed as metastatic tumor or plasmacytoma due to the unusual location and host factor.

Cerebral aspergillosis is rare and usually misdiagnosed because its presentation is similar to that of a tumor. The correct diagnosis is usually made intra-operatively. Cerebral abscess with fungal infection is extremely rare and few cases have been reported, but it carries a poor prognosis. A 73 year-old man presented with decreased visual acuity and paresis of the right cranial nerve III. Magnetic resonance imaging (MRI) revealed a mass in the right cavernous sinus, extened to the anterior crainial fossa and the superior orbital fissure. During surgery, a well encapsulated pus pocket was found, and histopathological examination of the mass resulted in the diagnosis of aspergillosis. Despite appropriate anti-fungal treatment, the patient eventually died from fatal cerebral ischemic change and severe brain swelling. The correct diagnosis of cerebral aspergillosis can only be achieved by histopathological examination because clinical and radiological findings including MRI are not specific. Surgical intervention and antifungal therapy should be considered the optimal treatment. Early diagnosis and aggressive antifungal treatment provide good results.

During the last five decades, long-term therapy with immunosuppressive agents such as pulse cyclophosphamide in conjunction with high-dose corticosteroids has enhanced both patient survival and renal survival in patients with diffuse proliferative lupus nephritis. Nevertheless, severe side effects such as infectious complications remain the main cause of morbidity and mortality. Central nervous system aspergillosis is uncommon but life-threatening in lupus patients. In this single-patient case study, carotid aneurysm with sphenoidal sinusitis was suspected when severe epistaxis occurred during cyclophosphamide pulse therapy. With anti-fungal therapy, a graft stent was successfully deployed to the aneurysm and specimens of sphenoidal mucosa showed typical hyphae, indicating aspergillosis. Three months after stopping voriconazole treatment, two cerebral aneurysms that were revealed on MR images were successfully removed by aneurysmal clipping. The patient remained alive at one-year follow-up with lupus nephritis in remission. The rarity and high mortality of aspergillus-related fungal aneurysms have led to most cases being recognized postmortem. However, such aneurysms must be diagnosed early to prevent fatal complications by performing appropriate management such as surgical procedure or endovascular intervention.

OBJECTIVETo explore the treatment and appropriate management of invasive aspergillosis infection following orthotopic liver transplantation.

METHODSThe clinical data of 576 cases who underwent orthotopic liver transplantation consecutively between January 2000 and January 2005 were analyzed retrospectively.

RESULTSThe prevalence of invasive aspergillosis infection was 1.74 (9/576), included 8 cases with pulmonary aspergillosis and 1 case with cerebral aspergillosis. The interval between transplantation and diagnosis were from 10 days to 2 months. Persistent or discontinuous low fever maybe the main clinical presentation after operation. Liposomal amphotericin B (AmBisome) is the mainly treatment for invasive aspergillosis infections, 5 patients were cured and 2 patients developed multi-organ aspergillosis infection died.

CONCLUSIONSThe clinical features of invasive aspergillosis infection following orthotopic liver transplantation were un-typical presentations in the early stage and easy to disseminate. Appropriate modification of immunosuppression therapy and early, high dose and long-term application of antifungal treatment is effective and safe to cure the disease.

Aspergillosis of the central nerve system is a rare disease, and intracranial fungal epidural abscess has not previously been described. We had been referred a 63-year old man who had 4 months history of hearing difficulty on his left ear and 3 months history of headache. Effusion of left middle ear was identified by otoscopy and tympanocentesis. Temporal bone CT showed soft tissue densities in middle ear, mastoid antrum and air cells with normal bony contours. T1 and T2-weigted MRI showed low signal intensity and peripheral rim enhancement after administration of gadolinium. Drainage of abscess through transmastoid approach was performed. Biopsy specimen showed septated fungal hyphae with Grocott's methanamine silver (GMS) and Periodic acid-schiff (PAS) stains. The authors hereby report a case of aspergillus epidural abscess of the middle cranial fossa.

BACKGROUND: We describe a case of skull base osteomyelitis due to invasive aspergillosis which had been aggravated after antifungal treatment but significantly recovered by dexamethasone. CASE REPORT: A 74-year-old male patient presented to neurology clinic complaining of sudden onset right-sided facial palsy and headache. Brain magnetic resonance imaging (MRI) and sphenoid sinus biopsy confirmed Aspergillus infection of skull base. He was treated with voriconazole for two months, but his headache was not relieved, and he additionally complained of vertigo and dysphagia. A subsequent MRI showed reduced enhancement of initial lesions, but increased thickness of surrounding dura mater. With an impression of paradoxical inflammatory response after antifungal treatment, parenteral dexamethasone was administered for one month while maintaining voriconazole. His symptoms improved thereafter. CONCLUSION: A paradoxical inflammatory response during antifungal treatment in the skull base aspergillosis aggravates the neurological symptom by thickening the dura mater, which can be recovered by dexamethasone.
