We describe a case of a 61-year-old man with a background of rheumatoid arthritis who presented to the emergency department with a single-reported episode of haemoptysis on the background of an upper respiratory tract infection. A CT scan revealed an incidental 40 mm mass in upper right lobe of the liver abutting the diaphragmatic surface. A subsequent positron emission tomography scan confirmed the mass and raised the possibility of another lesion in the liver raising the suspicion of malignancy. The case was complicated by the inability to perform a fine needle aspiration biopsy due to the mass' proximity to the diaphragm. After discussion with the patient, it was decided to resect the affected liver segment. Histological analysis of the mass revealed localised necrotising granulomatous inflammation suggestive of a rheumatoid nodule, which is seldom reported in the literature.
