Following near-drowning in fresh water, a 19-year-old man experienced severe adult respiratory distress syndrome, necessitating ventilatory support with positive end-expiratory pressure and high oxygen concentrations. Post-extubation, his course was highlighted by persistent hypoxemia and interrupted by a lung abscess which responded promptly to antibiotics. Pulmonary function tests were consistent with severe restrictive disease and chest radiograph revealed persistent bilateral alveolar and interstitial infiltrates. An open lung biopsy on the 26th hospital day showed interstitial fibrosis. Over the ensuing two months, the chest radiograph and pulmonary function tests returned towards normal. We attribute the pulmonary fibrosis to incomplete resolution of the alveolar interstitial pathology secondary to the near-drowning and exposure to high oxygen mixtures.

We present a retrospective study of 25 patients with spontaneous pneumothorax (three current), comprising 16 Saudis (nine males and seven females) and nine non-Saudis (eight males and one female), seen at the Asir Central Hospital, Abha, over a period of 45 months. Almost one-third of the patients (9/25) had no underlying cause discernible by our investigational facilities (chest x-ray, ultrasonography, computed tomographic scan, and flexible bronchofiberscopy). Underlying pneumonia (three patients), pulmonary tuberculosis (two patients), lung abscess (one patient), and congenital bullae (one patient) constituted the etiology in another third of the spontaneous pneumothorax patients. Other underlying pulmonary diseases precipitating spontaneous pneumothorax in the group included pulmonary fibrosis, metastatic mesothelioma, and immunosuppression in a medulloblastoma patient undergoing chemotherapy with the development of chickenpox. Closed thoracostomy tube drainage was the only method of treatment in 20 out of the 25 patients, with three failures of closed thoracostomy tube drainage needing thoracotomy and resection of blebs/bullae. The only complication was empyema in two of the patients. Two patients were successfully treated conservatively with observation alone.

IV heroin use is associated with several well-described complications, including noncardiogenic pulmonary edema, aspiration pneumonitis, ARDS, pneumonia, lung abscess, septic pulmonary emboli, and atelectasis. Foreign-body granulomatosis may develop when drug users inject solutions containing crushed oral tablets in which talc is used as filler and can be complicated by pulmonary fibrosis. The effects are distinct from pulmonary edema, which may occur acutely with heroin injection. We describe the case of a young female patient who was an IV heroin user who also smoked cigarettes, and presented with progressive dyspnea, hypoxia, and bilateral lung infiltrates. The final pathologic diagnosis in this case was one that had not been previously reported in IV heroin users.

A case of allergic bronchopulmonary aspergillosis (ABPA) is being described in a 52-year-old female patient who presented with a cavitary lesion on skiagram chest and simulating a lung abscess. Patient responded with the oral corticosteroid therapy with complete resolution of the initial radiographic abnormality. Despite various radiological presentations described in the literature, a lung abscess like presentation in ABPA is very rare and significant, because an early and correct diagnosis by the clinicians will help in early management of these cases to prevent the development of end-stage pulmonary fibrosis.

Fever of unknown origin (FUO) remains one of the most difficult diagnostic challenges. The causes of FUO can be various diseases located in different organs. The aim of the study was to determine the prevalence and nature of pulmonary lesions during FUO. One hundred and sixty one patients with FUO participated in this prospective study. We performed a detailed comprehensive history, physical examination, and a wide spectrum of tests. The most common causes of FUO were infections (39%), autoimmune conditions (28%), and neoplasms (17%). Lung lesions were found in 30% of patients. In this group 35% were infections, 30% autoimmune diseases, and 4% cancer. Among patients with respiratory infections, there were cases of tuberculosis, atypical pneumonia, lung abscess, and bronchiectases. Autoimmune pulmonary lesions were observed during vasculitis and systemic lupus. The causes of FUO in the group of patients with lung lesions were also pulmonary embolism, sarcoidosis, and pulmonary fibrosis. Chest CT played an important role in the diagnosis of the causes of FUO with pulmonary manifestations. Pulmonary lesions are a common cause of FUO. Most FUO with pulmonary lesions are recognized during infections and autoimmune diseases. An important part of diagnosing FUO is a detailed evaluation of the respiratory system.
