RESUMEN
INTRODUCTION: Symptomatic complications can occur after intravascular injection of cyanoacrylate glue. We report a case of pulmonary embolism following embolisation of an arteriovenous malformation (AVM). CASE REPORT: A 46-year-old woman was found to have an internal iliac AVM which was obliterated using N-butyl-2 cyanoacrylate (NBCA) mixed with lipiodol. The early clinical course was uneventful. On the third post-operative day she complained of sudden, transient chest tightness. On admission one hour later the chest pain had disappeared. Physical examination was normal. A chest roentgenogram showed multiple, dense, branched opacities scattered throughout both lung fields which were confirmed on HRCT, suggesting diffuse scattered embolism of iodine- labelled NBCA. The radiological signs persisted 6 months later. CONCLUSION: Endovascular treatment of arteriovenous malformations with NBCA can be responsible for symptomatic pulmonary embolism. This is not detectable radiologically in the absence of contrast medium. Radiologists should be aware of these often asymptomatic, but sometimes fatal, embolic complications.

INTRODUCTION: Bezoars result from the aggregation of ingested materials (food, drugs, hair) that accumulate at a certain anatomic level in the gastrointestinal tract. It is a rare condition, which is favoured by a reduction in intestinal motility, or by a primary abnormality reducing the patency of gastrointestinal tract. CASE REPORT: We present a case when acute respiratory symptoms revealed an oesophageal bezoar. The patient presented with compression of the posterior tracheal wall by an oesophageal bezoar. The diagnosis was confirmed by oesophageal endoscopy. Treatment consisted in endoscopy-guided fragmentation and removal of the bezoar followed by topical lavage. CONCLUSION: Oesophageal bezoars may account for compression of the posterior tracheal wall causing acute respiratory failure or difficult weaning from the ventilator. The close anatomic proximity between the gastrointestinal and respiratory tract may explain the impact of oesophageal bezoars on the respiratory tract.

INTRODUCTION: Lung involvement is rarely observed in the DRESS syndrome (Drug rash with eosinophilia and systemic symptoms). We report here a severe minocycline induced hypersensitivity syndrome with initial respiratory distress. CASE REPORT: A 19 year old man was admitted to the intensive care unit for acute respiratory distress with fever (400C), lymph node enlargement, hepatomegaly, splenomegaly and eosinophilia (1640/mm3). Bilateral alveolar opacities were observed on the chest x-ray. Sedation and mechanical ventilation rapidly became necessary because of severe hypoxaemia (47 mm Hg) and the sudden onset of severe aggressive behaviour. The diagnosis of DRESS was immediately suspected as the patient had been treated for acne with minocycline for 28 days, and IV corticosteroids (2 mmg/kg/day) were initiated. Skin lesions were delayed and appeared 3 days later. The outcome was uncertain for the following 6 weeks with serious disturbance of hepatic and renal function. Serology for human herpes virus (HHV6) was initially negative but became positive. One year later, after progressive withdrawal of corticosteroid therapy, the patient had made a complete recovery with no sequelae. CONCLUSION: The DRESS syndrome can cause considerable morbidity with multiple, severe visceral functional disturbances. Respiratory physicians should be aware of this syndrome as lung involvement can be serious and may precede cutaneous symptoms.

INTRODUCTION: Pyoderma gangrenosum is the ulcerative form of neutrophilic dermatoses. The most frequent extracutaneous localizations are the lungs, joints, and digestive tract. CASE RECORD: We report a case of Pyoderma gangrenosum, which presented first as an aseptic lung abscess. The first cutaneous lesions occurred 9 months later, with skin ulcerations on the thorax and on surgical scars. The histological diagnosis was made on skin biopsies. There was no associated abnormality except for IgA monoclonal gammapathy. Clinical improvement was noted with immunosuppressive treatment. DISCUSSION: This infrequent case report underlines that lung abscesses may be of non-infectious origin, that in Pyoderma gangrenosum, skin lesions may be come several months after extracutaneous manifestations, among which lungs abcesses are the most frequent.

The trachea is a pivotal organ of the respiratory tract. Rather than a genuine anatomic border, it acts as a crossroad in all respiratory infectious processes. Even though not strictly limited to the trachea, infections such as laryngotracheitis and tracheobronchitis are frequently diagnosed in children, in particular during the winter season. Infectious tracheitis etiologies are diverse and the distinction between viral and bacterial origins, albeit difficult, remains relevant considering the substantial differences in terms of gravity and therapeutic management. This literature review summarizes the microbiological and clinical aspects of community-acquired and nosocomial tracheitis in adults and children, as well as the adequate diagnostic and therapeutic approaches. It also highlights the emergence of fungal tracheitis in immunocompromised patients, of ventilator-associated tracheitis in intensive care medicine, and beyond all that the potential short and long-term consequences of tracheitis.

INTRODUCTION: Pulmonary localized forms of Waldenström's macroglobulinemia are rare. CASE REPORT: We report the observation of a 71-year-old woman with chronic cough and persisting alveolar opacities after several courses of antibiotics. Physical examination was unremarkable. Protein electrophoresis identified a monoclonal IgM in the serum. The lymphocyte immunophenotyping from the bronchoalveolar lavage was consistent with a B-cell lymphoma and Waldenström's macroglobulinemia was confirmed by the bone marrow biopsy. Chemotherapy with a combination of rituximab, fludarabine and cyclophosphamide improved the patient's symptoms and caused the pulmonary opacities to resolve. We discuss the various clinical and radiological pulmonary manifestations of this slowly progressive hematological condition. CONCLUSION: Pulmonary manifestations of Waldenström's macroglobulinemia result in various clinical and radiological patterns. A serum protein electrophoresis should be performed in cases of pleuropulmonary opacities persisting despite antibiotics.
