Skeletal changes mimicking intrathoracic disease on chest radiographs.

Various chest radiographs are illustrated to demonstrate features where bony changes may mimic intrathoracic disease. To confirm the skeletal origin and nature, further conventional radiographs often suffice, and the need for CT or scintigraphy may therefore be obviated. At the time of presentation for radiography of the chest, further pertinent clinical details can be obtained from the patient by the department staff, as required.

Fluid-calcium level in the thigh versus clinical diagnosis of a soft-tissue abscess: ultrasound features of dermatomyositis.

Ultrasound features of a fluid-calcium level in a soft-tissue mass in the thigh in dermatomyositis are described. As the mass was tender, a soft-tissue abscess required to be excluded by aspiration.

Incidental computed tomography diagnosis of a giant oesophageal leiomyosarcoma.

Leiomyosarcoma of the oesophagus is a very unusual tumour; only 53 cases have been reported in the English-language literature. A case is reported here of a patient with a giant leiomyosarcoma, without any symptoms of dysphagia. The diagnosis was made incidentally during CT examination of the chest for detection of possible pulmonary metastases from a coexisting carcinoma of the bladder.
