Chronic necrotizing pulmonary aspergillosis in an immunocompetent patient: report of a rare case

Chronic necrotizing pulmonary aspergillosis (CNPA) is a relatively uncommon manifestation of infection with Aspergillus spp. which mainly affects immunocompromised or immunostressed individuals with underlying lung diseases. Here, we present a case of mediastinum-involved CNPA in an immunocompetent patient with no symptoms and previous good health.     

Airway centered invasive pulmonary aspergillosis in an immunocompetent patient: case report and literature review

Invasive pulmonary aspergillosis is a major problem that occurs in severely immunocompromised patients. Airway centered invasive pulmonary aspergillosis is rare in patients with normal immunity or those without critical illness. Computed tomography (CT) is a very useful diagnostic modality, yielding characteristic imaging findings for early diagnosis of this infection in immunocompromised and immunocompetent patients. We describe the case of an immunocompetent patient with airway centered invasive aspergillosis, who was successfully treated with voriconazole.     

A novel cause of invasive pulmonary infection in an immunocompetent patient: Aspergillus candidus

Aspergillus candidus, a common contaminant of grain dust, may represent an important respiratory hazard to grain workers, considering its immunomodulating capability by producing p-terphenyl metabolites and terprenins, potent cytotoxic substances. However, there are only three cases of A. candidus infection in the English literature, one fatal solitary brain mass and two onychomycosis. We describe the first case of invasive pulmonary infection and skin abscesses due to A. candidus, determination of minimal inhibitory concentration for anti-fungals, and the successful treatment with liposomal amphotericin B and itraconazole. Possible mechanisms involved in the dissemination of infection in an immunocompetent host are discussed.     

Successful treatment of invasive pulmonary aspergillosis in an immunocompetent host

Immunocompromised individuals are susceptible to pulmonary Aspergillus infection, but invasive Aspergillus infection is extremely rare in the presence of normal immunity. A case of invasive pulmonary aspergillosis in an immunocompetent 57-year-old female who was successfully treated with liposomal amphotericin-B is reported here.     

Unusual radiological presentation and rapid fatal progression of invasive pulmonary aspergillosis in an immunocompetent young patient

Invasive aspergillosis occurs very rarely in immunocompetent hosts. We describe a 21-year-old female with no obvious immunosuppression or underlying lung disease, who presented with minimal symptoms and bilateral hilar prominence on chest X-ray. Invasive aspergillosis was diagnosed on an open lung biopsy. She deteriorated in the ensuing 2 weeks and died of a sudden massive haemoptysis. This initial radiological abnormality and the rapid clinical course of the disease in young immunocompetent patients have not been previously reported.     

Fatal invasive pulmonary aspergillosis presenting as profound hypoglycemia in a patient with anorexia nervosa

A 29-year-old woman with anorexia nervosa was admitted because of an episode of severe and persistent hypoglycemia. Chest X-ray showed multiple cavitary lesions and subsequent sputum culture revealed heavy growth of Aspergillus niger. In spite of intensive antimicrobial and supportive therapy, the patient died of respiratory failure and cardiovascular collapse. The potential relationships between anorexia nervosa, hypoglycemia, and infection are discussed.     

Allergic bronchopulmonary aspergillosis masquerading as invasive pulmonary aspergillosis.

Allergic bronchopulmonary aspergillosis (ABPA) is a noninvasive complex hypersensitivity reaction that occurs in immunocompetent patients with asthma. Aspergillus can invade and disseminate, but this more commonly occurs in severely immunocompromised patients receiving high-dose corticosteroids. We report the case of a 13-year-old immunocompetent male patient with moderate persistent asthma who appeared to have invasive pulmonary aspergillosis on radiographic studies. With further evaluation and workup, it was determined that the patient did not have invasive pulmonary aspergillosis, but that he met the diagnostic criteria for ABPA. Although initially there was a deceptive invasive appearance, proper identification of ABPA facilitated selection of corticosteroid treatment that resulted in prompt clearing of the concerning infiltrates.     

Pulmonary aspergillosis in an immunocompetent patient

SUMMARY: A case of an immunocompetent patient with severe Aspergillus infection and radiographic findings typically described with angioinvasive aspergillosis is presented. When Aspergillus is isolated from the sputum in a patient with normal immunity, invasive aspergillosis should be considered when there are extensive radiographic findings characteristic of invasive fungal disease.     

Pneumopericardium complicating invasive pulmonary aspergillosis: Case report and review

Summary Pneumopericardium, the presence of air in the pericardial space, is a rare disorder that is usually caused by trauma. We describe a patient given induction chemotherapy for acute myelogenous leukemia who developed pulmonary aspergillosis that resulted in pericarditis and pneumopericardium. He responded to antifungal treatment and recovered from granulocytopenia, but died early during the next course of chemotherapy. Two other reported cases of pneumopericardium associated with pulmonary aspergillosis are summarized.

Pneumoperikard als Komplikation einer invasiven Lungen-Aspergillose — Kasuistik und Übersicht —

Zusammenfassung Das selten vorkommende Pneumoperikard, definiert als Luftansammlung im Herzbeutel, wird meistens durch ein Trauma verursacht. Der Krankheitsverlauf eines mit Induktionschemotherapie wegen akuter myeloischer Leukämie behandelten Patienten wird beschrieben. Auf der Basis einer pulmonalen Aspergillusinfektion entwickelte sich eine Perikarditis und ein Pneumoperikard. Zwar konnte der Patient erfolgreich mit antimykotischer Therapie behandelt werden und erholte sich von seiner Granulozytopenie, verstarb jedoch im Verlauf der nachfolgenden Chemotherapie. Im weiteren werden aus der Literatur die Fälle von zwei anderen Patienten mit einem mit pulmonaler Aspergillose assoziierten Pneumoperikard erläutert.

     

Allergic bronchopulmonary aspergillosis: a rare cause of pleural effusion

Aspergillus fumigatus is one of the most ubiquitous of the airborne saprophytic fungi. Allergic bronchopulmonary aspergillosis (ABPA) is a syndrome seen in patients with asthma and cystic fibrosis, and is characterized by hypersensitivity to chronic colonization of the airways with A. fumigatus. We report the case of a patient with ABPA presenting with pleural effusion. A 27-year-old male was referred with recurrent right pleural effusion. Past medical history was remarkable for asthma, allergic sinusitis, and recurrent pleurisy. Investigations revealed peripheral eosinophilia with elevated serum immunoglobulin E and bilateral pleural effusions with bilateral upper lobe proximal bronchiectasis. Precipitating serum antibodies to A. fumigatus were positive and the A. fumigatus immediate skin test yielded a positive reaction. A diagnosis of ABPA associated with bilateral pleural effusions was made and the patient was commenced on prednisolone. At review, the patient's symptoms had considerably improved and his pleural effusions had resolved. ABPA may present with diverse atypical syndromes, including paratracheal and hilar adenopathy, obstructive lung collapse, pneumothorax and bronchopleural fistula, and allergic sinusitis. Allergic bronchopulmonary aspergillosis is a rare cause of pleural effusion and must be considered in the differential diagnosis of patients presenting with a pleural effusion, in particular those with a history of asthma.

Septic pulmonary emboli. A rare cause of bilateral pneumothorax in drug abusers

An intravenous drug abuser presented with bilateral pneumothorax. This is a previously unreported (to our knowledge) complication of septic pulmonary emboli secondary to right-sided endocarditis. This possibility must be considered in the differential diagnosis of pneumothorax in drug addicts.     

Control of invasive pulmonary aspergillosis with oral itraconazole in a bone marrow transplant patient.

Pulmonary aspergillosis following bone marrow transplantation carries a mortality of 94%, irrespective of current treatment. We treated a patient who had acquired aspergillosis some 80 days after allogeneic bone marrow transplantation, with oral itraconazole, 600 mg daily. After initial deterioration, clinical and radiographic resolution occurred during 3 months of therapy despite severe graft-vs.-host and cytomegalovirus disease. Itraconazole should be considered for therapy of pulmonary aspergillosis in this and other immunocompromised settings.     

Cryptococcal meningitis with pulmonary cryptococcoma in an immunocompetent patient: A case report

Rationale: Cryptococcal infections commonly occur in immunosuppressed patients and are uncommon in immunocompetent persons.Patient concerns: A 32 year old lady, active smoker presented with right chest pain, dry cough and loss of weight. Initial chest radiograph showed a lobulated lung mass in the right lower lobe. She developed headache and right cranial nerve palsy during admission. Various investigations were done including lumbar puncture, brain and chest imaging.Diagnosis: Cryptococcal meningitis with pulmonary cryptococcoma.Interventions: She received five months of effective antifungal treatment; however, the patient did not respond well. Subsequently, removal of pulmonary cryptococcoma was done. Outcomes: Her condition improved and she no longer had any headache.Lessons: Disseminated cryptococcosis is rare in immunocompetent patient. Our case highlights the importance of high index of suspicion and we postulate that lobectomy helped in reducing the cryptococcal burden in her body, thus facilitating better response to antifungal therapy.     

Angioinvasive pulmonary aspergillosis: presentation as massive pulmonary saddle embolism in an immunocompromised patient

A 33 year old woman with chronic myelogenous leukemia presented with clinical symptoms and hemodynamic signs suggestive of pulmonary embolism. Initial angiographic studies supported the diagnosis of a massive saddle pulmonary embolus, and an inferior vena cava filter was inserted. However, subsequent autopsy revealed unsuspected angioinvasive pulmonary aspergillosis with secondary in situ thrombosis. The clinical features and diagnostic considerations in immunocompromised patients presenting with the clinical picture of pulmonary embolism are discussed.
