Abstract:
A 21-year-old male with hereditary hemorrhagic telangiectasia underwent coil embolization for three pulmonary arteriovenous malformations (right S6c, right S10a, and left S6b). Three years after coil embolization, coil migration was observed in the right S6c and S10a, and a cavitary lesion developed between the two coils. Four years after embolization, the two coil lesions were found to have merged within the cavity. Right lower lobectomy was performed for severe recurrent hemoptysis. A histological examination revealed a granuloma with caseous necrosis related to Mycobacterium avium complex (MAC) infection around the cavity. The patient did not exhibit hemoptysis or MAC recurrence after resection.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
