[Intra-cavity aspergilloma complicating necrotising sarcoid granulomatosis].

INTRODUCTION

Necrotising sarcoid granulomatosis is a rare clinical entity, characterised by the development of nodular pulmonary opacities, the diagnosis if which is based on the identification of characteristic pathological lesions.

CASE REPORT: A 44-years-old male smoker presented with cough and fever. With the exception of a few basal crepitations clinical examination was normal. The chest x-ray showed multiple areas of alveolar consolidation scattered throughout both lung fields, some of which were cavitated. The thoracic CT scan confirmed the presence of cavitating nodules and hilar and mediastinal lymphadenopathy. Samples for mycobacteria were negative. A search for anti-neutrophil cytoplasmic antibodies was negative. Fibreoptic bronchoscopy was normal but transbronchial biopsies revealed giant cells. Lung biopsies taken by video thoracoscopy showed non-caseating granulomata with areas of fibrinoid necrosis and perivascular infiltration with lymphocytes, histology characteristic of necrotising sarcoid granulomatosis. Resolution occurred without treatment. The parenchymal lesions regressed leaving residual cavities. Four years later, following an episode of haemoptysis, the patient was found to have a squamous cell carcinoma (T1N0M0) and aspergillomas in the pulmonary cavities.

CONCLUSIONS

Our observation demonstrates that the cavities of necrotising sarcoid granulomatosis may be complicated by aspergillomas.
