Testicular Epidermoid Cyst on Diffusion-Weighted MR Imaging and ADC Map : A Case Report
نویسندگان
چکیده
Epidermoid cyst is a rare benign tumor, which accounts for 1-2% of all testicular tumors (1). It can be cured by organ preserving surgery. We experienced a case of pathologically confirmed testicular epidermoid cyst, which showed typical onion ring appearance on ultrasonography (US) and high signal intensity with internal alternating low signal intensity patterns on T2-weighted magnetic resonance imaging (MRI). The mass revealed homogeneous high signal intensity on diffusion weighted imaging (DWI) and low apparent diffusion coefficient (ADC) value. DWI is designed to detect Brownian motion of water molecules within tissues. It is a useful imaging tool to

Diffusion-weighted MR imaging of the brain: value of differentiating between extraaxial cysts and epidermoid tumors.
This study demonstrates the use of diffusion-weighted MR imaging in improving the specificity of the diagnosis of extraaxial brain tumors. Three surgically proved lesions (one arachnoid cyst and two epidermoid tumors) and two nonsurgically proved lesions (arachnoid and ependymal cysts) were evaluated with T1- and T2-weighted spin-echo studies followed by intravoxel incoherent motion (IVIM) MR i...
متن کاملUnusual CT and MRI? Appearance** of an Epidermoid Cyst: A Case Report
We report a case of an unusual epidermoid cyst in cerebellopontine angle that appeared hyperdense on computed tomography (CT) scanning, hyperintense on T1-weighted MR images and hypointense on T2/ FLAIRweighted magnetic resonance (MR) images. Diffusion-weighted imaging in post resection follow up study showed a focal restraction lesion, low on Apperent diffusion cooficent images.
متن کاملA Rare Case of Presacral Epidermoid Cyst in an Adult Male: Emphasis on Diffusion Weighted Magnetic Resonance Sequences in Preoperative Imaging
Epidermoid cyst of the presacral space is a rare congenital lesion of ectodermal origin. Presacral epidermoid cysts have been previously reported in women, however are extremely rare in males. We report a case of presacral epidermoid cyst in a 55-year-old male who presented to our emergency department with acute urinary retention and history of chronic constipation. A non-contrast computed tomo...
متن کاملQuantitative MR evaluation of intracranial epidermoid tumors by fast fluid-attenuated inversion recovery imaging and echo-planar diffusion-weighted imaging.
BACKGROUND AND PURPOSE Quantification of MR can provide objective, accurate criteria for evaluation of a given MR sequence. We quantitatively compared conventional MR sequences with fast fluid-attenuated inversion recovery (fast-FLAIR) and echo-planar diffusion-weighted (DW) MR imaging in the examination of intracranial epidermoid tumors. METHODS Eight patients with surgically confirmed intra...
متن کاملMediastinal epidermoid cyst in an old man with recurrent pneumonia: A case report
Mediastinal epidermoid cyst is a rare condition that is considered as a congenital disorder. Various manifestations from asymptomatic cases to serious symptoms may be found in these patients. However, some cases may be diagnosed incidentally. Here, we report an old man with recurrent pneumonia who demonstrated symptoms of respiratory distress and chest pain. The high resolution computed tomogra...
