Primary cardiac angiosarcoma: Imaging characterization.

This case report describes a 35-year-old female patient who presented with palpitations and shortness of breath. Imaging findings suggested a cardiac tumor, histopathology confirmed primary cardiac angiosarcoma. This tumor is highly aggressive, usually occurs in the right atrium, lacks specificity in clinical presentation, is prone to early metastasis, and has a poor prognosis. Echocardiography is the method of choice for early detection and is important in assessing tumor size, location, mode of attachment and whether cardiac function is impaired.

Diagnosis of membranous supravalvular aortic stenosis with severe aortic valve insufficiency.

Although the clinical manifestations of membranous supravalvular aortic stenosis (SVAS) are distinctive, its diagnosis remains challenging. Failure to initiate surgical treatment in a timely manner greatly increases the risk of sudden cardiac death. We report a case of membranous SVAS, detailing the clinical presentation and imaging manifestations.

Multimodal imaging of morning glory syndrome with persistent hyperplastic primary vitreous.

Morning glory syndrome (MGS) and persistent hyperplastic primary vitreous (PHPV) are congenital abnormity, which may be related to the increased incidence of systemic abnormalities and retinal detachment，diagnosed by ultrasound, identified by CT, MRI, and with the confirmation of fundus examination.

Prenatal ultrasound diagnosis of fetal isolated left innominate vein under the aortic arch: A case report.

Abnormalities of the left innominate vein beneath the aortic arch are exceedingly rare. While they may not exhibit overt clinical symptoms, misdiagnosis, or failure to diagnose can significantly complicate and increase the risk associated with cardiac interventional procedures.

The confusing pelvic cystic mass: A case of giant prostatic utricle cyst diagnosed by ultrasound.

The giant prostatic utricle cyst, located behindthe bladder with removable irregular mixed echo, communicating with the urethraat the level of the seminal colliculus, was diagnosed by ultrasound andverified by pathology and surgery.

[Expression and significance of basic fibroblast growth factor and transforming growth factor-beta 1 in mucoepidermoid carcinoma with different malignant degree].

OBJECTIVE: To study the expression and significance of basic fibroblast growth factor(bFGF)and transforming growth factor-beta 1 (TGF-beta1) in mucoepidermoid carcinomas with different malignant degree. METHODS: Using immunohistochemistry (IHC) staining technique, bFGF and TGF-beta1 proteins in the mucoepidermoid carcinoma tissues with different malignant degree, including well-differentiated, moderately differentiated and poorly differentiated mucoepidermoid carcinoma, and normal salivary gland tissue were detected. RESULTS: The positive rate of bFGF and TGF-beta1 in normal salivary glands were apparently lower than those in malignant mucoepidermoid carcinomas (P<0.05). The positive rate of bFGF in moderately and poorly differentiated mucoepidermoid carcinoma was higher than that in the well-differentiated carcinoma (P <0.05). However, the positive expression of bFGF showed no relationship between the moderately and poorly differentiated mucoepidermoid carcinomas. The positive rate of TGF-beta1 in moderately and poorly differentiated mucoepidermoid carcinomas was lower than that in the well-differentiated carcinoma (P<0.05). The positive expression of TGF-beta1 showed no relationship between the moderately and poorly differentiated mucoepidermoid carcinomas. The expression of bFGF and TGF-beta1 showed negative correlation (r=- 0.471, P=0.0003). CONCLUSION: The expression of TGF-beta1 may inhibit the development of the mucoepidermoid carcinoma, contrariwise, the expression of bFGF may prompt the development of the mucoepidermoid carcinoma. The expression of bFGF and TGF-beta1 has a negative correlation.
