Multi-detector row helical CT angiography provides more precise depiction of bronchial and nonbronchial systemic arteries than does conventional angiography.

These results demonstrate the higher frequency of abnormally enlarged bronchial and nonbronchial systemic arteries in patients who have chronic thromboembolic pulmonary hypertension compared with patients who have primary pulmonary hypertension; this finding could help distinguish these two entities on CT angiograms.

Abnormally enlarged systemic arteries were present in 13 of 32 patients, in whom there was a significantly higher frequency of clinical and/or radiographic features suggestive of lung infarction after embolotherapy.

Lipoma of the parotid gland is extremely rare, accounting for only 0,6% -4,4% of all parotid tumors. We present a rare case of lipoma of the superficial parotid lobe. A 68 -year-old man, presented in our department with a mass of the left parotid region. Clinical examination revealed a mobile, soft, non-tender mass in the area of the left parotid gland. MRI concluded to a lipoma of the superficial lobe of parotid gland. Parotidectomy preserving the facial nerve was performed. No complication nor recurrence were noted after a follow-up of 12 months. Lipoma arising in the parotid gland is extremely rare. Resection of this tumor requires full exposure of the facial nerve and its branches.
