Pilonidal cysts may be caused by a congenital pilonidal dimple. [14] Excessive sweating can also contribute to the formation of a pilonidal cyst: moisture can fill a stretched hair follicle, which helps create a low-oxygen environment that promotes the growth of anaerobic bacteria, often found in pilonidal cysts. The presence of bacteria and ...
The pooled incidence of OSD in patients with an atypical dimple, as observed in several studies, was significantly higher (8.8%) compared to patients with a simple dimple (0.6%). Given this increased risk, infants with atypical dimples require further evaluation through radiologic imaging and early referrals to neurosurgical specialists.
Imaging lenses and digital cameras (CCD or CMOS) are used to produce the final image. Live video processing can also be performed to enhance contrast during fluorescence detection and improve signal-to-background ratio. In recent years a number of commercial companies have emerged to offer devices specializing in fluorescence in the NIR ...

Marsupialization is the surgical technique of cutting a slit into an abscess or cyst and suturing the edges of the slit to form a continuous surface from the exterior surface to the interior surface of the cyst or abscess. Sutured in this fashion, the site remains open and can drain freely.
A hand-held surgical probe is an essential component of any image-guided surgery system as it provides the surgeon with a map of the designated area. [8] During the surgical procedure, the IGS tracks the probe position and displays the anatomy beneath it as, for example, three orthogonal image slices on a workstation-based 3D imaging system.
A pilonidal cyst is not a tumor; a dermoid cyst is, but often it is a benign one. Another source of confusion is that often no clear distinction is made between a cyst , an abcess , and a sinus . If you feel up to making all this clearer, please go to it!
Just as movies, TV, and web videos are to a substantive extent no longer separate technologies, but only variations on common underlying digital themes, so, too, are the X-ray imaging modes, and indeed, the term "X-ray imaging" is the ultimate hypernym that unites all of them, even subsuming both fluoroscopy and four-dimensional CT (4DCT ...
