Invasive aspergillus sinusitis with orbitocranial extension

Abstract

Context:Invasive sinonasal aspergillosis is a silently progressive disease that, left untreated, may invade the adjacent intracranial and intra-orbital compartments incurring serious morbidity.Aim:To evaluate our results of a collaborative surgical management plans for patients with invasive sinonasal aspergillosis with orbitocranial extension.Setting and Design:Retrospective study.Materials and Methods:Between the years 2000 and 2012, 12 patients with Aspergillus sinusitis with orbitocranial extension were treated at our institution. Preoperative CT and MRI scans were done in all cases and cerebral angiography in two patients with subarachnoid hemorrhage (SAH). Surgical combined transcranial and endonasal approaches to the skull base were considered in all patients. Adjuvant antifungals were administered postoperatively with regular clinical and radiologic follow up.Results:All cases had a long history of headache and nasal obstruction (n = 12). Five presented with unilateral proptosis, one with meningitis, one with epilepsy, two with SAH, and one patient presented with trigeminal neuralgia. Craniotomy alone was chosen for the patients with isolated sphenoiditis (n = 2) while a combined cranial and endonasal approach was elected for the other patients (n = 10). Adjuvant antifungal therapy was used for 3-12 months. Patients were followed up clinically and radiologically for an average 36-month period (range = 12-50 months) with disease eradication achieved in eight patients (67%). Two died as consequence to SAH. Follow up also showed that three patients (25%) had sinunasal recurrence requiring evacuation through an endonasal approach.Conclusions:Surgical intervention, with adjuvant antifungal therapy, aiming for safe total removal of the fungal burden, whenever feasible, has a major role in the management of invasive sinonasal aspergillosis with orbitocranial extension with minimal morbidity and good outcomes.

A treated case of rhinocerebral zygomycosis with aspergillosis: a case report from India

“…Zygomycosis and aspergillosis are two serious fungal infections that generally present with a high case fatality rate, especially among immunocompromised patients [2, 10]. Our patient was known to have been suffering from diabetes for the previous 5 years with poor compliance to treatment, leading to a hyperglycaemic state.…”

Stereotactic Radiosurgery as Initial Surgical Management for Elderly Patients with Trigeminal Neuralgia

“…Recent reports have yielded evidence that factors such as pain relief, recurrence, complications, and length of stay do not significantly differ between elderly and younger patients [10,11]. For patients who present with various medical or surgical comorbidities, MVD risks must be compared to the outcomes of less invasive strategies.…”

“…Most of them focus on evaluating the efficacy and safety of MVD in this population [4,10,11], yet no study suggested how to manage patients who are considered higher risk for more invasive surgical procedures such as MVD. The achievement of long-lasting pain relief with minimal associated sensory deficits is the hallmark of MVD for TN.…”

Update Opportunistic Infections of the Central Nervous System in Patients with Iatrogenic Immunosuppression

“…Infections with Aspergillus fumigatus frequently involve the paranasal sinuses [19]; therefore, as a rule, an otorhinolaryngologist should be consulted in all patients with Aspergillus fumigatus infection [20].…”
