Introduction: The detection of solitary pulmonary nodules (SPNs) has increased due to widespread use of computed tomography; nevertheless, chest radiographs still remain the basic routine examination. The aim of the study was to estimate the detection of SPNs in routine chest X-rays in hospitalized patients and to assess the incidence of malignancy in newly diagnosed SPNs. Material and methods: We analyzed 5726 routine chest radiographs of patients admitted to the Department of Internal Diseases, Pneumology and Allergology in 2004 and 2005. Most of the patients were admitted to hospital due to emergency reasons. The malignant nature of the nodules was confirmed by pathological examination. The nature of benign nodules was confirmed either by pathological examination or based on radiological criteria: no growth within 2 years of radiological follow up, regression in control radiograms or CT scans, benign pattern of calcification. Results: Among the 5726 radiograms we found 116 newly diagnosed SPNs (2.2%). Twenty-four nodules (21%) were malignant: NSCLC in 21 cases and metastases in 3 cases. Fifty-one nodules (44%) were benign. In 19 patients (16%) SPNs proved to be artefacts or erroneously interpreted extrathoracic lesions. In 22 cases (19%) there was no final diagnosis (lack of data, diagnostic procedure renunciation). Conclusion: The incidence of newly detected SPNs in chest X-rays was 2.2%. Most SPNs were benign. About 21% of SPNs were diagnosed as malignant.
Dyspnoea is most often caused by disorders of the respiratory and/or cardiovascular systems. Much less often it is brought about by the displacement of abdominal organs into the thoracic cage. Hiatal hernias may give rise to diagnostic difficulties, as both clinical and radiological symptoms suggest different disorders. Computed tomography is the method of choice when making a diagnosis. We have presented a series of 7 cases of giant hiatal hernias, each with a varying course of the disease, clinical symptoms, radiological features and prognoses. In two of the cases, the hernias were of a post-traumatic nature. Four cases of large diaphragmatic hernias were found in elderly patients (over 90 years old). An advanced age and numerous coexisting chronic diseases disqualified most of the patients from surgical treatment despite the hernias' large sizes. In only one case was fundoplication performed with a good end result. Two patients died, and an extensive hernia was the cause of one of the deaths. Upper gastrointestinal symptoms were present only in a few of the patients. An early diagnosis of giant hiatal hernia is crucial for the patients to undergo prompt corrective surgeries.
