A 62-year-old man diagnosed with glioblastoma multiforme and currently under chemoradiation therapy presented with massive haemoptysis. Chest computed tomographic scan disclosed a round-shaped formation in the right upper lobe with contrast agent leakage indicating active bleeding (figure 1). Pathological examination after right upper lobectomy revealed a pseudoaneurysm of the pulmonary artery caused by invasive mucormycosis (figure 2).

After candidiasis and aspergillosis, mucormycosis is the third most frequent invasive mycosis in immunocompromised patients. In 25% the lungs are the main site of manifestation and in these cases a high mortality is reported.1 An interesting characteristic of Mucorales species is the angioinvasion which leads to rupture of vessels with massive haemorrhage.2
