Epidermoid Cysts of the Testicle: Sonographic and MR Imaging Features
OBJECTIVE. The purpose of this study is to analyze the appearance of testicular epidermoid cysts on high-resolution sonography and MR imaging and correlate imaging features with histopathologic findings.
CONCLUSION. Intratesticular epidemıoid cysts may show imaging features that correlate with their histopathologic findings. Concentric rings of alternating hypo- [...]

Summary: Chemical analysis of the contents of a so-called bright epidermoid of the posterior fossa with unusual CT and MR imaging characteristics suggested that [...]
Epidermoid cyst of intrapancreatic spleen is described but epidermoid cyst occurring in the pancreas itself is not documented. We report a 36-year-old man who presented with abdominal pain radiating to the back. On ultrasonography, a multilocular cyst was seen in the head of the pancreas. Fine-needle aspiration cytology suggested a diagnosis of epidermoid cyst, which [...]
Epidermoid and dermoid cysts are benign lesions encountered throughout the body, with 7% occurring in the head and neck area and 1.6% within the oral cavity. They represent less than 0.01% of all oral cavity cysts. The cysts can be defined as epidermoid when the lining presents only epithelium, dermoid cysts when skin adnexa are [...]
Intraspinal epidermoid tumors are rare. Most of these tumors occur spontaneously, while others may be acquired. Occurrence of epidermoid tumor following surgery for spinal dysraphism has been reported till 15 years from the day of surgery. We report here a case of Cauda equina syndrome due to intraspinal epidermoid tumor following 38 years of surgery [...]
A 65-year-old man with a history of alcoholism and smoking (60 pack-year), was admitted for exploration of a left submandibular tumefaction of one year’s duration. There were no similar cases in the family and no history of contact with tuberculosis. There was no history of surgical or radiological intervention in the submandibular region.
Physical examination revealed [...]
A 27-year-old man was referred for ultrasonographic (US) evaluation of a painless right testicular mass. The mass had been present for 3 years and had recently increased in size. Physical examination revealed no evidence of lymphadenopathy or gynecomastia. Laboratory test results, including levels of the tumor marker serum ß–human chorionic gonadotropin, were normal. The patient [...]
Epidermoid cyst in the spinal cord is a rare condition, constituting only 0.6–1.1% of all spinal tumors.1 The majority of spinal epidermoid cysts are subdural and extramedullary, while intramedullary localization is very rare.
Intramedullary epidermoid cyst is common in lumbosacral and thoracic regions; two frequent localizations are T4–T6 and T11–T12, while only three cases have been [...]
