title: Massive hemangioma or lymphedema? A case with a diagnostic dilemma.
abstract: The authors present an unusual case of massive enlargement of the right lower extremity that was treated as lymphedema secondary to filarial infection. A multiple-method approach beginning with scintigraphy led to the diagnosis of massive hemangioma with probable associated lymphatic proliferation. Abnormal local proliferation of vascular and lymphatic tissue is a developmental anomaly that is difficult to diagnose or characterize, even with histopathologic data. Individual imaging methods may also yield nonspecific findings. Blood-pool scintigraphy, therefore, has a definitive role to play in assessing such complex lesions.
