Adult Langerhans' cell histiocytosis with multisystem involvement: A case report.

Rationale: Langerhans' cell histiocytosis (LCH), also called histiocytosis X, is an uncommon disorder manifesting in a variety of ways. Although LCH can involve various organs including bone, skin, and lymph nodes, multisystem involvement of LCH is rare in adults.

Patient Concerns: A 31-year-old woman first presented to our hospital with left leg pain.

Relationship between current smoking, visual CT findings and emphysema index in cigarette smokers.

Purpose: To evaluate whether visual CT findings could account for the effect of current smoking.

Methods: 500 CT scans were visually evaluated within each lobe. A multivariate model for emphysema index was constructed containing previously described confounders in addition to the visual components associated with smoking status.

Pancreas Ductal Adenocarcinoma and its Mimics: Review of Cross-sectional Imaging Findings for Differential Diagnosis.

Ductal adenocarcinoma is the most common pancreatic neoplasm. A variety of pancreatic lesions mimic pancreas ductal adenocarcinoma (PDAC), such as high-grade neuroendocrine tumors, small solid pseudopapillary tumors, metastases, focal autoimmune pancreatitis, and groove pancreatitis. These occasionally look similar in images, but they have differential diagnosis points.

LI-RADS v2017 categorisation of HCC using CT: Does moderate to severe fatty liver affect accuracy?

Objectives: To compare the sensitivity of Liver Imaging Reporting and Data System (LI-RADS) v2017 for diagnosis of hepatocellular carcinoma (HCC) using multiphasic computed tomography (CT) between patients with and without moderate to severe fatty liver (MSFL).

Methods: This retrospective study included a total of 106 high-risk patients with 112 pathologically proven HCCs who underwent multiphasic CT. Patients were classified as MSFL (24 men, 2 women; mean age, 59.

Various congenital anomalies of the inferior vena cava: review of cross-sectional imaging findings and report of a new variant.

The inferior vena cava (IVC) is an important structure receiving a large amount of venous return and is associated with various congenital disorders. Advances in diagnostic imaging and its increasing accessibility have led to an increase in the incidental detection of IVC anomalies. Congenital anomalies of the IVC are not uncommon and are occasionally critical to treatment planning.

Estimation of Diastolic Filling Pressure with Cardiac CT in Comparison with Echocardiography Using Tissue Doppler Imaging: Determination of Optimal CT Reconstruction Parameters.

Objective: To determine the optimal CT image reconstruction parameters for the measurement of early transmitral peak velocity (E), early peak mitral septal tissue velocity (E'), and E / E'.

Materials And Methods: Forty-six patients underwent simultaneous cardiac CT and echocardiography on the same day. Four CT datasets were reconstructed with a slice thickness/interval of 0.

The dose of cyclophosphamide for treating paraquat-induced rat lung injury.

Background/aims: Cyclophosphamide (CP) is a promising treatment for severe cases of paraquat (PQ) poisoning. We investigated the effective dose of CP for mitigating PQ-induced lung injury.

Methods: Adult male Sprague-Dawley rats were allocated into five groups: control, PQ (35 mg/kg, intraperitoneal injection), and PQ + CP (1.

Remarkable Effect of Gefitinib Retreatment in a Lung Cancer Patient With Lepidic Predominat Adenocarcinoma who had Experienced Favorable Results From Initial Treatment With Gefitinib: A Case Report.

Gefitnib is an oral agent of epidermal growth factor receptor tyrosine kinase inhibitor, and it has a certain efficacy against non-small cell lung cancer. There are some reports that the non-small cell lung cancer patients who experienced disease progression after responding to gefitinib were again sensitive to re-administration of gefitinib following temporary cessation of gefitinib. This is the case report showing a remarkable effect of gefitinib re-treatment in a patient with metastatic invasive adenocarinoma who had experienced favorable results from the initial treatment with gefitinib.

The area of ground glass opacities of the lungs as a predictive factor in acute paraquat intoxication.

Even though plasma paraquat (PQ) levels have known to be an informative predictor, many patients succumb at low PQ levels in acute PQ intoxication. This study was designed to see whether the high resolution computerized tomography (HRCT) of the lungs would be a predictive measure in acute PQ intoxication. HRCT of the lungs was obtained from 119 patients with acute PQ intoxication on 7 days after PQ ingestion.
