The radiologic differential diagnosis of diffuse lung diseases characterized by multiple cysts or cavities.
A variety of pulmonary diseases have diffuse cystic abnormalities within the lungs, including emphysema, cystic bronchiectasis, desquamative interstitial pneumonia, lymphocytic interstitial pneumonia, usual interstitial pneumonia, lymphangioleiomyomatosis, Langerhans histiocytosis, cystic metastasis, Wegener granulomatosis, Pneumocystis carinii pneumonia, pulmonary paragonimiasis, and septic pulmonary emboli. CT can easily detect cystic abnormalities as common features in many diseases. However, some characteristic pattern of them can facilitate specific diagnoses.

Multicenter StudyRespiratory bronchiolitis-associated interstitial lung disease: radiologic features with clinical and pathologic correlation.
The purpose of this work was to describe the radiographic and CT findings in patients with respiratory bronchiolitis-associated interstitial lung disease (RB-ILD) and to correlate them with clinical, physiologic, and pathologic features. ⋯ The CT findings of RB-ILD are centrilobular nodules, ground-glass opacity, and air trapping. These radiologic features, in patients with a history of heavy cigarette smoking, may differentiate RB-ILD from other interstitial lung diseases.

Is coagulopathic liver disease a factor in spontaneous cerebral hemorrhage?
Hepatic dysfunction is a common cause of thrombocytopenia and coagulopathy and has been reported as a causal factor in spontaneous intracranial hemorrhage. We attempt to define the prevalence of intracranial hemorrhage in patients with severe liver disease and coagulopathy. ⋯ Contrary to past reports, we find no instance of spontaneous intracranial hemorrhage in patients with coagulopathic liver disease presenting with acute mental status changes. Therefore, unless associated with trauma, spontaneous intracranial hemorrhage in coagulopathic liver disease is very uncommon.

Right-sided colonic diverticulitis is an uncommon but clinically significant condition as it closely mimics other common acute right-sided abdominal conditions like acute appendicitis and cholecystitis. CT can provide a rapid and accurate diagnosis of this condition and thereby prevent unnecessary laparotomy and surgical procedures since it is essentially a benign self-limiting condition requiring medical treatment. It is the aim of this pictorial essay to describe the CT findings and increase awareness among radiologists of this condition.
