Pulmonary inflammatory myofibroblastic tumour with unusual octreoscan uptake: two reports

Inflammatory myofibroblastic tumour (IMT) is a relatively uncommon lesion and occurs in nearly every site of the body. Patients with IMT are usually asymptomatic, with a solitary nodule or mass detected by routine chest radiograph [1]. Many diagnostic procedures can be applied to make the diagnosis: computed tomography (CT) scan to outline nodule growth and perfusion, [18F]-2-fluoro-deoxy-D-glucose (FDG)-PET/CT scan to evaluate metabolic activity and 111In-Diethylene triamine pentaacetic acid (DTPA)-D-Phe1 scan (octreoscan) to investigate somatostatin analogue receptors, often present in a variety of neuroendocrine tumours (NETs). We present two cases of pulmonary IMT clinically misdiagnosed as carcinoid tumours due to a positive octreoscan.
