RESUMO

O Sarcoma da Artéria Pulmonar é um tumor raro, apresentando-se com sinais e sintomas inespecíficos, simulando por vezes o Tromboembolismo Pulmonar (TEP), o que torna o seu diagnóstico difícil e tardio.

A este propósito os autores apresentam um caso de um homem de 59 anos, ex-fumador, internado por dispneia de esforço, toracalgia e sintomas gerais.

Portador de uma radiografia e TAC torácicas, ambas evidenciando imagens sugestivas de Trombose da Artéria Pulmonar Direita.

Analiticamente e antes de qualquer terapêutica: Inibidor Lúpico ↑ e anticardiolipina IgM +.

Presumido diagnóstico inicial de TEP crónico em doente com provável Síndroma de Hipercoaguabilidade, iniciou terapêutica hipocoagulante, com melhoria.

Reinternado 2 meses após alta por agravamento clínico e radiológico. Proposto e aceite para Tromboendarterectomia Pulmonar, sob circulação extracorporal e paragem cardiocirculatória em hipotermia profunda (18ºC). Durante a cirurgia constatou-se a presença de «mega-artérias pulmonares» preenchidas por massa trombosada que se estendia às ramificações arteriais segmentares. Após a exérese dessa massa houve necessidade de realizar Pneumectomia direita por hemorragia progressiva incontrolável.

Veio a falecer ao 7.º dia de pós-operatório, por ARDS em pulmão único.

Resultado Anatomopatológico: Sarcoma da Artéria Pulmonar com Metastização Pulmonar e Pleural.

ABSTRACT

Primary Pulmonary Artery Sarcoma is a rare entity, which shares some clinical features with Thromboembolic Pulmonary Disease (TEPD), complicating differential diagnosis.

The authors report a Clinical Case of a Primary Pulmonary Artery Sarcoma in a 59 years old man, admitted with a history of dyspnoea on exertion, chest pain and general symptoms. Chest X-ray, Computed Tomography Scan, Angiographies and Magnetic Resonance Imaging suggested TEPD.

Blood Analysis performed before anticoagulation therapy: Lupus Anticoagulant - and Ig M Anticardiolipin+.

Our presumptive initial diagnosis was TEPD in a patient with a hypercoagulable state.

Intravenous heparin was started, with some clinical improvement but 2 months later he was readmitted, due to clinical and radiological deterioration. Pulmonary Thromboendarterectomy was considered but a right pneumonectomy was necessary because of bleeding. He died of ARDS in a single lung in the 7 th day after surgery. Pathology revealed pulmonary artery sarcoma with pulmonary and pleural metastases.
