1/60. Rhinocerebral mucormycosis: a case of a rare, but deadly disease.

    Rhinocerebral mucormycosis is a rare fungal infection of the nasal cavity and sinuses that can spread to the orbits and cranium within days. Its presentation can be confused with those of sinusitis, viral infections, diabetic ketoacidosis, or carotid sinus thrombosis, and it is often missed at early presentation. survival is directly linked to early detection and treatment. We present a case of rhinocerebral mucormycosis and discuss the literature on its early signs and symptoms, pathophysiology, and treatment options.

2/60. Rhinocerebral mucormycosis: report of two cases.

    Rhinocerebral mucormycosis is a rare opportunistic infection caused by fungi. It is commonly fatal and aggressive infection localised paranasal sinuses and orbit. We report two cases had necrotising infection on the left nasolabial region. Despite aggressive surgical debridement and medical treatment, the patients died 6 and 7 days after admission. Plastic Surgeons should be aware when they have a patient with rapidly developing soft tissue infection over the paranasal sinuses and periorbital region. Combined treatment is mandatory for these patients. It usually results in death, but powerful efforts may save the patient.

3/60. survival after rhino-orbital-cerebral mucormycosis in an immunocompetent patient.

    OBJECTIVE: Rhino-orbital-cerebral mucormycosis is usually associated with a poor prognosis and is almost exclusively seen in immunocompromised patients. We report the third documented case of rhino-orbital-cerebral mucormycosis caused by Apophysomyces elegans (a new genus of the family Mucoraceae first isolated in 1979) in an immunocompetent individual. Orbital exenteration and radical debridement of involved adjacent structures combined with intravenous liposomal amphotericin resulted in patient survival. DESIGN: Interventional case report. METHOD: A 59-year-old immunocompetent white man sustained a high-pressure water jet injury to the right inner canthus while cleaning an air conditioner filter. He later had "orbital cellulitis" develop that did not respond to antibiotics and progressed to orbital infarction. Imaging studies and biopsy results led to a diagnosis of mucormycosis. Tissue culture grew Apophysomyces elegans, a new genus of the family Mucoraceae first isolated in 1979. Orbital exenteration and radical debridement of involved adjacent structures, combined with intravenous liposomal amphotericin, resulted in patient survival. RESULTS: After orbital exenteration and debridement of involved adjacent structures along with intravenous liposomal amphotericin, our patient has remained free from relapse with long-term follow-up. CONCLUSIONS: The agent causing this case of rhino-orbital-cerebral mucormycosis (Apophysomyces elegans) contrasts with the three genera most commonly responsible for mucormycosis (rhizopus, Mucor, and absidia) in that infections with this agent tend to occur in warm climates, by means of traumatic inoculation, and in immunocompetent patients. Rhino-orbital-cerebral mucormycosis should be considered in all patients with orbital inflammation associated with multiple cranial nerve palsies and retinal or orbital infarction, regardless of their immunologic status. A team approach to management is recommended for early, appropriate surgery and systemic antifungal agents.

4/60. mucormycosis of the nose and paranasal sinuses.

    Rhinocerebral mucormycosis is an invasive fungal infection initiated in the paranasal sinuses that frequently progresses to orbital and brain involvement. If recognized early, involvement is limited to the nasal cavity and paranasal sinuses. Diabetics in poor control are at greatest risk, however, any immunocompromised individual may be infected. The mainstays of therapy are reversal of immunosuppression, systemic amphortericin B, and surgical debridement. survival has improved dramatically, yet deaths still occur if the infection is not recognized and not treated early in its course or if the source of immunocompromise is not reversible. Several case examples illustrate the clinical course of this unusual, but potentially fatal, fungal infection. Taxonomy, clinical presentation, diagnosis, and management of mucormycosis of the paranasal sinuses are reviewed in detail.

5/60. Acute subdural hematoma and intracerebral hemorrhage. Rare complications of rhinocerebral mucormycosis.

    Rhinocerebral mucormycosis is a short-term and often rapidly lethal fungal disease. It is generally seen in uncontrolled cases of diabetes with ketoacidosis. This case exhibits many of the features of a typical fulminating rhinocerebral mucormycosis. However, the fatal complications of acute subdural hematoma and massive intracerebral hemorrhage due to rupture of aneurysm, as demonstrated by angiography, are unique clinical manifestations of patients with rhinocerebral mucormycosis.

6/60. mucormycosis in a transplant recipient.

    mucormycosis classically occurs in patients who have uncontrolled diabetes who develop rhinocerebral disease. A fatal case of rhinocerebral infection caused by rhizopus arrhizus in a 53-year-old man who had received a renal homograft three years previously is reported. Only five similar cases have been documented, all since 1970. Although direct smears of the purulent nasal exudate revealed the presence of numerous Gram-negative bacilli, later identified as haemophilus influenzae, the diagnosis of mucormycosis was made by demonstrating the typical broad, nonseptate branched hyphae in the necrotic tissue obtained by surgical debridement of the paranasal sinuses. culture of this material revealed growth of mold-like fungus which, upon direct microscopic examination, showed sporangiophores bearing spherical sporangia arising directly from a cluster of root-like structures of rhizoids. Despite the immediate institution of therapy with amphotericin b postoperatively, the patient died 48 hours later. Subsequently, the rhizopus isolated was shown to be resistant to both amphotericin b and 5-fluorocytosine. The present case and two others stress the importance of an aggressive diagnostic approach to patients suspected of having mucormycosis, because the usual microbiologic technics are frequently, inexplicably, unsuccessful, and possibly even misleading in this disease.

7/60. Mucor endophthalmitis.

    PURPOSE: To report on a case of type 2 diabetes, with eyelid gangrene and endophthalmitis as a presenting manifestation of rhino-orbito-cerebral mucormycosis. RESULTS: CECT head showed proptosis, mucosal thickening in the ethmoid sinus and hypodense lesions in the frontal and occipital lobes. Vitreous tap showed right angle branched aseptate hyphae consistent with mucormycosis. CONCLUSIONS: A diabetic patient presenting with sudden loss of vision, eyelid gangrene and endophthalmitis, involvement by an angio-invasive fungus-like mucormycosis is an important consideration.

8/60. Lethal rhinocerebral phycomycosis in a healthy adult: a case report and review of the literature.

    A lethal case of rhino-orbital-cerebral phycomycosis (mucormycosis) in an otherwise healthy man is presented. The clinical, radiologic, and ante mortem surgical pathology associated with microbiologic examinations failed to yield the diagnosis of fungal infection as the cause of a clinical presentation of acute sphenoid sinusitis with a fulminant cavernous sinus thrombosis. No similar case report was found in review of the literature. There is a need for a high degree of suspicion in this condition to improve the uniformly poor prognosis in this devastating infectious disease. Emphasis is placed on the necessity for early tissue or microbiologic diagnosis with appropriate histologic stains and fungal cultures. Treatment consists of extensive surgical excision of all necrotic or questionably viable tissue in conjunction with alternate-day amphotericin b therapy.

9/60. Fatal rhino-orbito-cerebral mucormycosis in an apparently normal host: case report and literature review.

    Fungal infections of the central nervous system (CNS) are fortunately rare but remain challenging problems occurring mostly in immunocompromised individuals, with protean manifestations, unpredictable course and unfavorable outcome in many cases despite aggressive neurosurgical intervention and recent antifungal drugs. Rhino-orbito-cerebral mucormycosis is a potentially lethal opportunistic fungal infection with rapid progression and high mortality. Its pathogenic nature becomes evident when the patient's general resistance is compromised. We present a case of an invasive rhino-orbito-cerebral mucormycosis in an apparently normal adult who initially developed mild paranasal sinusitis and later developed status epilepticus and despite an aggressive management died. Interesting clinical, neuroimaging and histological findings are described, and the possibility of fatal mucormycosis in an apparently normal host is highlighted.
