30. Minimal excision technique for epidermoid (sebaceous) cysts
Match Strength: 15.766

Epidermoid cysts are asymptomatic, dome-shaped lesions that often arise from a ruptured pilosebaceous follicle. The minimal excision technique for epidermoid cyst removal is less invasive than complete surgical excision and does not require suture closure. The procedure is easy to learn, and most physicians experienced in skin surgery can perform the procedure after three to five precepted sessions. It involves making a 2- to 3-mm incision, expressing the cyst contents through compression and extracting the cyst wall through the incision. Gauze or a splatter shield should be used to protect ... Read More »

BACKGROUND: Appropriate differentiation between epidermoid-dermoid and arachnoid cysts is important for patient management. MRI has had limitations in differentiating these two types of cysts, especially in the region of the spinal cord. OBJECTIVE: To evaluate the role of diffusion-weighted (DW) MRI for differentiation between spinal arachnoid and epidermoid-dermoid cysts. MATERIALS AND METHODS: Four children underwent conventional and DW MRI. Turbo spin-echo imaging was used to obtain DW images. RESULTS: On conventional MRI, low T1-W and high T2-W signal was present in all lesions. DW imaging ... Read More »

46. Atypical CT and MRI aspects of an epidermoid cyst.
Match Strength: 14.112

We report a case of an unusual epidermoid cyst (EC) of the cerebellopontine angle that appeared hyperdense on computed tomography (CT) scanning, hyperintense on T1-weighted MR images and hypointense on T2-weighted magnetic resonance (MR) images. Diffusion-weighted imaging showed a hypointense lesion. We discuss imaging characteristics of ECs, explain the atypical findings in our case and confirm that the signal seen on diffusion-weighted images in the EC is related to a T2 effect ... Read More »

49. Presacral epidermoid cyst. A case report.
Match Strength: 13.988

INTRODUCTION: Most of the primitive cystic neoplasms arising in the retrorectal presacral space are congenital. Presacral epidermoid cysts are classified as a type of developmental cysts, resulting from an error during the embryogenesis. They have a slowly-progressive growth that only lately can cause clinically remarkable symptoms. Most patients are middle-aged women. They are often asymptomatic. The discovery is almost always casual. It happens during controls like US, CT MRI, gynecological visit. The surgical treatment must be effected for a correct diagnosis of nature of the lesion and to ... Read More »
