BACKGROUND Nodules of cells showing a striking histological similarity to those of arachnoid villi have previously been found closely adjacent to pulmonary venules in several diseases associated with alveolar hypoxia or pulmonary oedema including mitral stenosis, plexogenic pulmonary arteriopathy, pulmonary thromboembolism, and chronic obstructive pulmonary disease. METHODS Histological secti...

Introduction The pleuro-pulmonary changes associated with rheumatoid arthritis are well known. A rare and more specific lesion is the subpleural or intraparenchymal rheumatoid nodule. The pulmonary nodules usually occur in patients with severe disease with subcutaneous nodules and high titres of rheumatoid factor.

Percutaneous preoperative localisation of breast tumours using a hook-wire needle is a standard radiological practice. The use of a hook-wire in preoperative localisation of pulmonary nodules under computed tomography guidance has also been described in overseas publications. We describe herein our local experience with the use of a hook-wire needle that is primarily used in breast tumours in p...
