Abstract
AbstractLipomas are the most common form of benign soft tissue tumors in humans, occurring infrequently in visceral organs. Pulmonary lipomas are seen rarely and can occur such as an endobronchial (80%) or peripheral parenchymal (20%) lesion. Less than 10 cases of lung peripheral lipoma are described in literature, none cavitated. We report the clinical case of a 51-year-old emphysematous smoker man with a peripheral intrapulmonary middle-lobe cavitating lipoma, revealed during a routine chest X-ray for emphysema, subsequently confirmed by high-resolution computed tomography (HRCT) and positron emission tomography (PET)–CT. Some hypotheses are made about the origin of cavitation. Biopsy and surgery were not done due to the fully benign nodular features at imaging. The nodule was unchanged till 2 years, last follow-up with low-dose HRCT. It is probably useful to choose a conservative approach with a follow-up, if there is a high suspicion of benignity.
