RESUMO
OBJECTIVE: The purpose of this study was to assess CT findings in a series of patients with hydrocarbon pneumonitis after diesel fuel siphonage. CONCLUSION: The characteristic CT findings of hydrocarbon pneumonitis after diesel fuel siphonage are the presence of air-space consolidations with predominant right middle lobe involvement and areas of low attenuation within consolidation. Occasionally, bronchoalveolar lavage is needed to confirm the diagnosis of hydrocarbon pneumonitis by the presence of lipid-laden macrophages on the basis of a history of diesel fuel aspiration.

There are widely diverse causes of pancreatitis. Gallstone and alcohol have been recognized as the most common causes of pancreatitis accounting for 90% of cases. However, acute and chronic pancreatitis may also result from a variety of uncommon causes. The determination of the etiology is important for patient management and prevention of recurrence. Sludge is the most common cause of idiopathic or recurrent acute pancreatitis. Endoscopic ultrasonography is considered as the most accurate diagnostic test for this abnormality. Computed tomography (CT) and magnetic resonance imaging (MRI) have only a limited role in the diagnosis of sludge. However, papillitis observed on the contrast-enhanced CT and MR may provide clues to the detection of pancreatitis secondary to sludge, a small stone or a recently passed stone. Radiological studies, clinical presentation and laboratory data can be helpful in determining the etiology of unusual causes of pancreatitis such as anatomic anomalies, autoimmune pancreatitis, groove pancreatitis, and traumatic pancreatitis.
