Invasive aspergillosis has increasingly been recognised to cause significant morbidity and mortality in immunocompromised patients. Fever unresponsive to broad-spectrum antibiotics is the earliest and most common sign of an invasive fungal infection. As invasive Aspergillus infections are usually acquired by inhalation of Aspergillus conidia, symptoms of a pulmonary infection such as cough, rales and marked pleuritic chest pain can be noted early in the course, whereas hemoptysis typically comes late after neutrophil recovery. Aspergillus infections of the upper respiratory tract may also involve the nasal cavity or sinuses resulting in nasal obstruction, epistaxis, facial pain, periorbital swelling and even palate destruction. Primary cutaneous infections present as non-purulent ulcerations and may be seen in association with implantable intravenous devices. Other sites of infections, such as the central nervous system, originate from dissemination of molds and may be suspected when focal neurological findings or meningism develop. The recognition of symptoms associated with invasive aspergillosis in patients at risk should prompt further diagnostic procedures, as an early diagnosis and immediate institution of antifungal therapy might improve the treatment outcome in this life-threatening condition.

Aspergillosis is an infrequent but commonly fatal infection among HIV-infected individuals. We review 342 cases of pulmonary Aspergillus infection that have been reported among HIV-infected patients, with a focus on invasive disease. Invasive pulmonary aspergillosis usually occurs among patients with <50 CD4 cells/mm3. Major predisposing conditions include neutropenia and steroid treatment. Fever, cough, and dyspnea are each present in >60% of the cases. BAL is often suggestive, but biopsy specimens are necessary for definite diagnosis. Amphotericin B is the mainstay of treatment and mortality is > 80%. Avoiding neutropenia and judicious use of steroids may be helpful in prevention. Aggressive diagnostic approach, early initiation of treatment, adequate dosing of antifungals, and close follow-up may improve the currently dismal prognosis.

A 49-year-old man with a cough productive of black sputum was admitted to our hospital. A chest CT scan was done. Cystic, estatic changes, and intra-capsula fluid surrounding an enhanced wall in the right S10 were seen. Aspergillus niger was detected by sputum culture. Aortic angiography showed that an aberrant artery originated from the inferior diaphragmatic artery and penetrated the right S10. The preoperative diagnosis was lung sequestration associated with aspergillosis. The operative procedure included right lower lobectomy and ligation of the aberrant artery. Postoperatively, Pryce-type intralobar sequestration infected with aspergillus was diagnosed. Microscopically, the parenchyma was distorted and chronic inflammation was present. Hyphae of aspergillus were found within the lumen of the cyst.

A 29-year-old man was admitted to the hospital because of a high fever and dyspnea. He had a history of bronchial asthma and had had a bullectomy of the right lung at 15 years of age. He had visited a family physician because of fever and non productive coughing. Medications had no effect on his symptoms, and dyspnea developed. A chest X-ray film showed total collapse of the right lung, and he was referred to our hospital. Laboratory data showed eosinophilia and a high titer of IgE. Total obstruction of the right main stem bronchus by mucous plug was found during fiberoptic bronchoscopy. Aspergillus was detected by pathological examination of bronchial lavage fluid. Tests for aspergillus-specific IgE and IgG antibody were positive, as was immediate skin reactivity to Aspergillus. Allergic bronchopulmonary aspergillosis (ABPA) was diagnosed. Infusion and inhalation of a corticosteroid and fluconazole were effective; the symptoms resolved and X-ray findings improved. While migratory infiltration, proximal bronchiectasis and segmental or subsegmental atelectasis caused by a mucous plug are common X-ray findings in allergic bronchopulmonary aspergillosis, total collapse is rare.

20 years old man with history of acute allergic alveolitis 7 years ago, was admitted to hospital because of dyspnea, fever and cough after massive exposition to organic dust. Corticosteroids were introduced. During 3-weeks treatment respiratory failure progressed. Chest x-ray showed massive bilateral nodular opacities. Antibiotic therapy was not effective. The autopsy revealed invasive pulmonary aspergillosis. Presence of precipitins to aspergillus fumigatus was confirmed postmortem. Diagnostic difficulties are discussed.

A 23-year-old man with bronchial asthma presented with fever, cough, and sputum. A chest X-ray examination showed pulmonary infiltrations in the left upper and lower lung fields with central bronchiectasis. Although his temperature came down with antibiotics, pulmonary infiltrations persisted with cough and sputum. Following bronchoscopy and an allergological examination, the patient was given a diagnosis of allergic bronchopulmonary aspergillosis (ABPA) based on Rosenberg's criteria, including peripheral blood eosinophilia, a high serum IgE level, immediate skin reaction to Aspergillus antigen, positive precipitating antibodies, and Aspergillus fumigatus in sputum. The patient was treated with itraconazole instead of corticosteroids. His respiratory symptoms, eosinophilia, and pulmonary infiltration then disappeared, and his IgE serum level gradually decreased. An antifungal agent alone was effective in treating this ABPA patient.

Invasive pulmonary aspergillosis is an opportunistic infection occurring in a background of severe immune depression. The majority of cases occur in patients who have malignant hematologic disease, particularly during chemotherapy induction or consolidations phases for acute non-lymphocytic leukemia. The principal risk factors are profound (PN < 500 per mm3) and prolonged (very high risk beyond 20 days) neutropenia, perturbed phagocyte function and cellular immune deficiency (AIDS, immunosuppressive treatment in organ and bone marrow recipients). Clinically, invasive pulmonary aspergillosis presents as acute non-specific pneumonia with cough, chest pain and fever. The severe infection rapidly becomes life-threatening. The development of massive hemoptysis is a major risk. We report four cases of invasive pulmonary aspergillosis in patients who had hemoptysis. All four patients developed non-specific pneumonia resistant to broad-spectrum antibiotics during post-chemotherapy aplasia. Computed tomography of the thorax and bronchoscopy with bronchoalveolar lavage was performed due to the occurrence of hemoptysis. In the first two cases, the patients were recovering from aplasia. The thoracic CT scan showed evidence of a cavitating mass with peripheral vessels. Bronchoscopy findings suggested mucosal lesions. The patients were managed surgically. Pathology confirmed the diagnosis of invasive pulmonary aspergillosis with the presence of ischemic necrosis of the pulmonary parenchyma harboring numerous aspergillus filaments. Outcome was favorable and chemotherapy was re-initiated in one case. These two patient died from their hematological disease a few months later. The other two patients remained in aplasia. A CT of the thorax showed multifocal infiltration with vascular contact. Bronchoscopy was again suggestive. One patient developed massive hemoptysis with respiratory distress. Embolization was performed but the patient died two days after onset of hemoptysis. In the last case, embolization was successful and outcome was favorable enabling a bone marrow allograft; the patient died a few months later from the hematological disease. The potential gravity of hemoptysis in the course of invasive pulmonary aspergillosis should lead to early treatment with emergency CT scan and, if possible, bronchoscopy with bronchoalveolar lavage to establish the therapeutic strategy based on surgical excision or embolization of the pulmonary or bronchial arteries.

A 65-year-old woman was admitted to our hospital with a dry cough and pulmonary infiltrates. Chest radiograph and CT revealed mucoid impaction and consolidations. Peripheral blood eosinophilia and elevated serum IgE were observed. Aspergillus niger was cultured repeatedly from her sputum, but A. fumigatus was not detected. Immediate skin test and specific IgE (RAST) to Aspergillus antigen were positive. Precipitating antibodies were confirmed against A. niger antigen, but not against A. fumigatus antigen. She had no asthmatic symptoms, and showed no bronchial hyperreactivity to methacholine. Thus, this case was diagnosed as allergic bronchopulmonary aspergillosis (ABPA) without bronchial asthma due to A. niger, an organism rarely found in ABPA. The administration of prednisone improved the symptoms and corrected the abnormal laboratory findings.

Invasive aspergillosis has been increasingly recognized as causing significant morbidity and mortality in immunocompromised patients but has never been diagnosed by fine-needle thyroid aspiration. A 24-year-old female with systemic lupus erythematosus presented with cough, shortness of breath, and fever of unknown origin unresponsive to broad-spectrum antibiotics. History and physical examination failed to indicate a source of infection. An 111In white blood cell scan showed thyroid localization. Physical examination revealed a multinodular goiter with a left dominant nodule. Fine-needle aspiration biopsy of a thyroid nodule revealed branching hyphae suggestive of Aspergillus sp. Despite immediate and aggressive treatment with amphotericin B and fluconazole, the patient died of overwhelming infection.

A 66-year-old man was referred to our hospital because of cough. Chest X-ray films showed complete atelectasis of the left lung. Serum CYFRA was elevated. Bronchoscopic examination disclosed a white polypoid lesion occluding the left main bronchus. A biopsy specimen from the lesion revealed numerous aspergillus hyphae. Oral itraconazole (100 mg) and weekly endobronchial instillation of fluconazole were administered. Three months later, on the 12th bronchoscopic examination, the tumor occluding the left main bronchus was detected after the removal of aspergillus, and the biopsy findings yielded a diagnosis of squamous cell carcinoma. Aspergillosis complicated by lung cancer without cavity formation is very rare, and compounded the difficulty of diagnosing lung cancer in this case.
