Generalised lymphangiomatosis is a rare disease that is characterized by widespread bony and soft tissue involvement of lymphangioma. Radiological evaluation is crucial because the site and extent of the lymphangioma are important prognostic factors. The computed tomography, ultrasonography and magnetic resonance images showed sharply defined, non-enhanced cystic lesions involving the mediastinum, bones, spleen, lung, and lower neck. We report here a case that was referred to us for investigation of marked cardiomegaly.
