A rare cause of delayed contrast enhancement on cardiac magnetic resonance imaging - Infective endocarditis

Although there have been a few reports about the magnetic resonance (MR) imaging features of infective endocarditis (IE), delayed contrast enhancement attributable to fibrosis has not been previously described. The case of a 4-year-old girl who was diagnosed with IE based on positive blood culture results and echocardiographic findings is presented. At cardiac MR imaging, late phase contrast-enhanced images revealed a significant enhancement suggesting fibrosis secondary to IE

Increased carotid artery flow rate in a patient with Parry-Romberg syndrome

Parry-Romberg syndrome (PRS) is a rarely seen connective tissue disorder and is characterized by chronic inflammation of the face. Anti-nuclear antibodies, anti-extractable nuclear antigens and skin biopsy are helpful for diagnosis. In this study, we determined that the external carotid artery blood flow rate was faster on the affected side than on the unaffected side. We believe that patients suffering from PRS who also have central nervous system symptoms must be examined for vascular structure by Doppler ultrasonography, magnetic resonance imaging or conventional angiography

Diagnosis of Nipple Discharge: Value of Magnetic Resonance Imaging and Ultrasonography in Comparison with Ductoscopy

Background: Pathologic nipple discharge, which is a common reason for referral to the breast imaging service, refers to spontaneous or bloody nipple discharge that arises from a single duct. The most common cause of nipple discharge is benign breast lesions, such as solitary intraductal papilloma and papillomatosis. Nevertheless, in rare cases, a malignant cause of nipple discharge can be found. Aims: To study the diagnostic value of ultrasonography, magnetic resonance imaging, and ductoscopy in patients with pathologic nipple discharge, compare their efficacy, and investigate the importance of magnetic resonance imaging in the diagnosis of intraductal pathologies. Study Design: Diagnostic accuracy study. Methods: Fifty patients with pathologic nipple discharge were evaluated by ultrasonography and magnetic resonance imaging. Of these, 44 ductoscopic investigations were made. The patients were classified according to magnetic resonance imaging, ultrasonography, and ductoscopy findings. A total of 25 patients, whose findings were reported as intraductal masses, underwent surgery oincluding endoscopic excision for two endoscopic excision. Findings were compared with the pathology results that were accepted as the gold standard in the description of the aetiology of nipple discharge. In addition, magnetic resonance imaging, ultrasonography and ductoscopy findings were analysed comparatively in patients who had no surgery. Results: Intraductal masses were reported in 26 patients, 20 of whom operated and established accurate diagnosis of 18 patients on magnetic resonance imaging. According to the ultrasonography, intraductal masses were identified in 22 patients, 17 of whom underwent surgery. Ultrasonography established accurate diagnoses in 15 patients. Intraductal mass was identified in 22 patients and ductoscopy established accurate diagnoses based on histopathologic results in 16 patients. The sensitivities of methods were 75% in ultrasonography, 90% in magnetic resonance imaging, and 94.6% in ductoscopy. The specificities were 66.7% in ultrasonography, 66.7% in magnetic resonance imaging, and 40% in ductoscopy. Intraductal papillomas were mostly observed as oval nodules with well-circumscribed smooth margins within dilated ducts and persistant in the dynamic analysis. Lesions that protruded into the lumen of the ducts, either solitary or multiple, were characteristic ductoscopy findings of our patients who were diagnosed as having papilloma/papillomatosis. Conclusion: Magnetic resonance imaging and ductoscopy had no statistical superiority over each other, however they were superior to ultrasonography in the diagnosis of pathologic nipple discharge. Magnetic resonance imaging may be highly sensitive for diagnosing nipple discharge with new techniques and sequences and a non-invasive method that more advantageous for showing ductal tree visualization and is able to detect completely obstructed intraductal lesion

PSEUDOANGIOMATOUS STROMAL HYPERPLASIA OF THE BREAST ( MORPHOLOGICAL AND IMMUNOHISTOCHEMICAL ANALYSIS OF 14 CASES).

Pseudoangiomatous stromal hyperplasia (PASH) is an uncommon, benign mesenchymal lesion of the breast. Histologically, it is characterized by complex, anastomosing, empty, slit-like spaces that are lined by spindle cells in a dense collagenous stroma. We have evaluated 14 PASH cases morphologically and immunohistochemically, using antibodies against CD34 and progesterone receptor and reviewed the relevant literature. Also, we have evaluated the mast cell population of the lesions, using Giemsa stain. All of the cases were women presenting with a mass in the breast. The diameter of the lesions ranged from 1 cm to 13,5 cm (mean diameter 4 cm). The spindle cells, lining the slit-like spaces, were immunoreactive for anti CD34 whereas all were negative for anti progesterone receptor. The mean mast cell count was 17,5/10 HPF. Although differential diagnosis of PASH includes several mesenchymal lesions appropriate macroscopic sampling and immunohistochemistry are usually sufficient for proper diagnosis. Nevertheless, detection of immunostaining for CD34, using immunohistochemistry, may support the morphologic diagnosis
