A dedicated adrenal washout CT protocol consists of a non-contrast, a contrast -enhanced scan with a delay of 60-90 sec and a delayed scan at 15 minutes. The ROI should encompass at least 2/3 of the lesion to ensure a representable assessment. Absolute enhancement wash out ⩾ 60% is proof of an adenoma [5,6,8].

DISCUSSION. Pleomorphic adenomas consist of neoplastic myoepithelial cells mixed with neoplastic ducts and stroma. 3 They occur commonly in the salivary gland of the head and neck, but rarely in the airway. 3–5 Because of the slow growing nature of these tumors, patients with pleomorphic adenomas rarely experience sudden-onset respiratory symptoms. . Because of this insidious progression

Förra måndagen, den 21 november, opererades jag. Op tog ca 4 timmar och jag var helt nedsövd under tiden. SUMMARY: We present 4 cases of carcinoma ex pleomorphic adenoma of the parotid gland. In 3 of the 4 cases, diffusion-weighted and apparent diffusion coefficient (ADC) mapping images clearly revealed carcinoma as a hypercellular area with low ADC values and pleomorphic adenoma as a hypocellular area with high ADC values.
