Occipital nodular fasciitis easily misdiagnosed as neoplastic lesions: A rare case report.

Background: Nodular fasciitis (NF) is a benign disease originating from fascial tissue and most commonly occurs in the extremities, followed by the trunk, head, and neck. NF of the head and neck occurs mainly in the face and neck, and it has not been reported in the occipital region.

Case Summary: A 30-year-old man was admitted because of a mass in the left occipital region.

Endometrial stromal sarcoma extending to the pulmonary artery: A rare case report.

Background: Endometrial stromal sarcoma (ESS) is a rare malignant mesenchymal tumor. Early in the disease, the findings on magnetic resonance imaging are similar to those of leiomyoma. When the lesion involves both vascular and cardiac tissue, it might be misdiagnosed as intravenous leiomyomatosis, which is not common in the clinic.

Prevalence and prognostic impact of comorbidities and peripheral blood indices in sarcomas.

Background: The prognostic impact of comorbidities in patients with sarcomas is not well defined. The aims of this study were to examine the implications of comorbidities and abnormal peripheral blood indices in patients with sarcomas.

Methods: A population-based database was assembled to extract patients with sarcoma in Hong Kong between January 2004 and March 2018.

[The investigation and prognosis in patients with non-alcoholic fatty liver disease and coronary vulnerable plaque].

To investigate the prevalence and prognosis of non-alcoholic fatty liver disease (NAFLD) complicated with coronary vulnerable plaque (VP). Consecutive patients were included who had undergone coronary artery CT angiography (CCTA) from January 1, 2011 to January 30, 2015 at the First People's Hospital of Neijiang. NAFLD was diagnosed according to the liver imaging findings (liver/spleen CT ratio≤1.

Neuroimaging findings of cerebral syphilitic gumma.

Cerebral syphilitic gumma is a rarely reported disease of the central nervous system. Magnetic resonance imaging (MRI) is an important diagnostic method for syphilitic gumma. The present study aimed to describe and characterize neuroimaging results from 6 patients with pathologically diagnosed cerebral syphilitic gumma.

Cortical morphologic changes in recent-onset, drug-naïve idiopathic generalized epilepsy.

Purpose: Only a few studies have investigated the brain morphology abnormalities in structural MRI in patients with drug-naïve idiopathic generalized epilepsy (IGE) and mainly focused on brain volume changes. In the present study, we aimed to investigate the changes in three morphologic measurement differences including cortical thickness, cortical volume, and surface area using FreeSurfer in a pediatric cohort of recent-onset, drug-naïve IGE.

Methods: Forty-five recent-onset, drug-naïve patients diagnosed with IGE and 32 demographically matched healthy controls were recruited.

Chronic hepatitis B: correlation of abnormal features on T2-weighted imaging and dynamic contrast-enhanced imaging with hepatic histopathology.

Objectives: To investigate the correlations between abnormal features on liver magnetic resonance (MR) T2-weighted imaging (T2WI) and dynamic contrast-enhanced (DCE) imaging and the pathological findings in chronic hepatitis B.

Materials And Methods: Sixty-seven patients with chronic hepatitis B and 18 normal controls who were undergone an abdominal MR imaging were analyzed retrospectively. Patchy hyperintensities, linear and reticular hyperintensities in liver and periportal edema on T2WI and abnormal intrahepatic enhancement signals on DCE imaging were noted.

Diffusion-weighted magnetic resonance imaging for the detection of metastatic lymph nodes in patients with lung cancer: A meta-analysis.

The aim of the present meta-analysis was to evaluate the diagnostic value of diffusion-weighted imaging (DWI) in differentiating metastatic from non-metastatic lymph nodes in patients with lung cancer. A systematic literature search was performed to identify eligible original studies. The quality of included studies was assessed using 'quality assessment of diagnostic accuracy studies' (QUADAS-2).

Transformation, migration and outcome of residual bodies in the seminiferous tubules of the rat testis.

Experiments were performed to study the transformation, migration and outcome of residual bodies (RBs) in the seminiferous tubules of the rat testes. One part of the testes from adult Sprague-Dawley rats was used to generate paraffin sections to observe RBs and RB precursors through specific staining, and the other part of the testes was used to generate ultrathin sections to observe RBs under a transmission electron microscope. Deep blue particles of different sizes were observed in some seminiferous tubules through specific staining for RBs and RB precursors.

Angiomyolipoma of the rib: A rare case report.

Angiomyolipoma is a benign mesenchymal tumor, most commonly arising from the kidney. With the exception of the liver, extrarenal angiomyolipoma is an infrequent entity that may be misdiagnosed as other tumors. Angiomyolipoma occurring in the skeleton is an extremely rare occurrence and often difficult to differentiate from other bone diseases.

Observations on the expression of human papillomavirus major capsid protein in HeLa cells.

Background: The goal of this study was to identify the nature of the inclusion bodies that have been found in HeLa cells (cervical cancer immortal cell line) by electron microscope and to determine whether the major capsid protein (L1) of human papillomavirus (HPV) can be expressed in HPV-positive uterine cervix cancer cells.

Methods: HPV L1 protein expression in HeLa cells was detected with anti-HPV L1 multivalent mice monoclonal antibody and rabbit polyclonal anti-HPV L1 antibody by ELISA, light microscope immunohistochemistry, electron microscope immunocytochemistry and Western blotting assays. Reverse transcriptional PCR (RT-PCR) was performed to detect the transcription of L1 mRNA in HeLa cells.
