Pulmonary tumour thrombotic microangiopathy (PTTM) is a rare complication of
cancer, which can be lethal due to progressive pulmonary hypertension (PH).
Several case reports have demonstrated that imatinib, a platelet-derived growth
factor receptor-tyrosine kinase inhibitor, can improve severe PH in patients with
PTTM.We describe the case of a 56-year-old woman. Her mean pulmonary arterial
pressure (mPAP) was 47?mm Hg, and her dyspnoea worsened rapidly over several
days. Although pulmonary embolism was not observed on CT, enlargement of the
para-aortic lymph nodes was detected. Gastro-oesophageal endoscopy revealed
signet-ring cell carcinoma. We diagnosed her as having PTTM based on her clinical
course, and started treatment with imatinib. Five days after its administration,
her mPAP decreased dramatically. She was discharged and lived without symptoms of
PH until her death due to systemic metastasis of carcinoma. In some cases of
PTTM, imatinib may be an effective therapeutic option for PH.
