Variability of radiological and clinical features in cases with usual interstitial pneumonia without honeycombing.

Background: Usual interstitial pneumonia (UIP) cases without honeycombing (possible UIP) included various CT features and was often difficult to diagnose.

Purpose: This study aimed to classify the cases with possible UIP on CT features using cluster analysis and evaluate the features of subsets of participants and the correlation of prognosis.

Materials And Methods: The study included 85 patients with possible UIP in the 2011 idiopathic pulmonary fibrosis (IPF) guideline with radiological diagnosis.

Pleuroparenchymal fibroelastosis-like lesions in patients with interstitial pneumonia diagnosed by multidisciplinary discussion with surgical lung biopsy.

Purpose: The present study aimed to evaluate the significance of Pleuroparenchymal fibroelastosis (PPFE)-like lesions in predicting prognosis in patients with chronic interstitial pneumonia (IP).

Method: The present study enrolled 207 patients with IP in whom surgical lung biopsy was performed. Among the patients enrolled in the present study, 77 had idiopathic pulmonary fibrosis (IPF), 15 had nonspecific interstitial pneumonia (NSIP), 13 had chronic hypersensitivity pneumonitis (CHP), 41 had connective tissue disease (CTD), three had PPFE, and 58 had unclassifiable diagnosis.

[Three Cases of Bleeding from Advanced Gastric Cancer during Chemotherapy Treated with Transcatheter Arterial Embolization(TAE)].

Case 1: An 71-year-old man underwent chemotherapy with S-1 plus trastuzumab to treat type 3 gastric cancer that was diagnosed as Stage IV tubular adenocarcinoma(T4b[Panc], N3, H0, CY1, P0, M1). For anemia and active bleeding from the tumor, transcatheter arterial embolization(TAE)was performed with metallic coils on the splenic artery. Infarction of the spleen and left pleural effusion were observed.

Fourth ventricular mixed germ cell tumor demonstrating adipose tissue in a young adult.

We report a case of fourth ventricular mixed germ cell tumor (GCT) in a 20-year-old man. Neuroradiological investigations revealed a fourth ventricular hemorrhagic tumor with adipose tissue. We suspected mixed GCT because adipose tissue was seen preoperatively, but mixed GCT occurring after childhood in this location has not previously been reported.
