Pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is the most common primary pulmonary lymphoma. There are limited studies on imaging features of pulmonary MALT lymphoma. We present the computed tomography (CT) manifestations of pulmonary MALT lymphoma and the correlation between CT manifestations and clinical characteristics. Patients (n = 53) with histologically confirmed pulmonary MALT lymphoma who underwent chest CT scanning were retrospectively analyzed. Evaluated findings included distribution of pulmonary lesions, morphological pattern of appearance, contrast enhancement features, size, presence of thoracic lymphadenopathy, and secondary associated features. Pulmonary MALT lymphoma was observed in multiple (79%) and bilateral (66%) disease with random distribution (≥70%) of pulmonary lesions. The most frequent morphological pattern was consolidation (n = 33, 62%), followed by nodule (n = 23, 43%) and mass (n = 11, 21%). Common associated features were air bronchograms and bronchiectasis, especially cystic bronchiectasis and angiogram sign. Asymptomatic patients had less consolidation and bronchiectasis than did symptomatic patients. Cystic bronchiectasis was only observed in the symptomatic group. In conclusion, pulmonary MALT lymphoma manifests as diverse patterns on CT scans. Consolidation combined with cystic bronchiectasis was a characteristic late sign, which may assist in differential diagnosis. High-resolution CT images and multiplanar reconstruction techniques are helpful for accurately determining imaging manifestations.

BackgroundIsolated nocturnal hypertension (INH) has been studied among the general population and hypertensive patients. However, little insight is available on the prevalence of INH and its role in target-organ damage among patients with chronic kidney disease (CKD).Methods and ResultsWe recruited 1282 CKD patients admitted to our hospital division. Patients were divided into 4 groups: INH; isolated daytime hypertension; day–night sustained; and ambulatory normotension. Multiple linear regression analyses were used to evaluate the correlation between INH and renal/cardiovascular parameters. A total of 262 (20.44%) CKD patients had isolated nocturnal hypertension and 651 (50.78%) had day–night sustained hypertension, whereas only 350 (27.30%) patients showed normotension and 19 (1.48%) had isolated daytime hypertension. Multivariate logistic regression analysis showed that INH was associated mainly with age, estimated glomerular filtration rate, clinic diastolic blood pressure, and that INH was determined only by age, estimated glomerular filtration rate, and clinic diastolic blood pressure. The prevalence of impaired renal function, left ventricular hypertrophy, and carotid intima-media thickness in patients with INH were higher than in normotensive patients (P<0.05), whereas impaired renal function and left ventricular hypertrophy in these patients were lower than patients in the day–night sustained hypertension group (P<0.05). INH was correlated with estimated glomerular filtration rate, left ventricular mass index, and carotid intima-media thickness according to multiple linear regression analyses.ConclusionsThe prevalence of INH in CKD patients was high, and INH was correlated with target-organ damage in CKD patients.
