Can FDG-PET help in the diagnosis of Pulmonary Tumor Thrombotic Microangiopathy?
FDG-PET may be a useful imaging modality for the difficult antemortem diagnosis of pulmonary tumor thrombotic microangiopathy.
Pulmonary tumor thrombotic microangiopathy (PTTM) is histopathologically characterized by proliferation of intimal myofibroblasts in the small pulmonary arterioles, induced by tumor microemboli. Patients develop rapidly progressive and severe cardiopulmonary failure, and the clinical course of this disease is fatal. Conventional radiologic findings are often minimal or nonspecific, making diagnosis difficult before death. We report 2-(F-18)-fluoro-2-deoxy-d-glucose positron emission tomography (FDG-PET) images of PTTM, which illustrate the characteristic findings of this clinical entity. FDG-PET can be helpful for the diagnosis of PTTM.
Tashima et al. (Wed,) conducted a case report in Pulmonary tumor thrombotic microangiopathy (PTTM). 2-(F-18)-fluoro-2-deoxy-d-glucose positron emission tomography (FDG-PET) was evaluated. FDG-PET imaging illustrates characteristic findings of pulmonary tumor thrombotic microangiopathy and can be helpful for its diagnosis.
