The normal and pathologic
ischiorectal fossa at CT and MR imaging.
The final pathology report was moderately differentiated squamous cell carcinoma with deep margin (from the sacrum,
ischiorectal fossa, and ischial bone) positive for tumor cells.
Secondary extensions and accompanying abscesses were defined by their anatomical location such as intersphincteric, extrasphincteric, ischioanal, or
ischiorectal. Fluid collections with peripheral contrast enhancement and visualized as the extension of fistula were defined as abscess.
Foreign body removed from
ischiorectal area with the help of forceps.
The anaesthetic mixture was deposited in the sphincter complex approximately 3 cm from the anal verge through the anococcygeal ligament into the
ischiorectal fossae to the level of levator ani muscle.
reported a thoroughly sampled case displaying a bland, smooth muscle lesion from the left
ischiorectal fossa of a 42-year-old woman [20].
MRI of the pelvis revealed extensive necrotic tumor extending to the right pelvic sidewall including ischium,
ischiorectal fossa, perineum, insertion of corpus cavernosum, scrotal base, and right gluteal area, with involvement of the subcutaneous tissues (Figure 2 and supplementary materials (available here)).
Computed tomography is mainly needed to accurately detect the extent of spread of the abscess, particularly to the
ischiorectal fossa and perineum [12, 14].
Few cases have been reported affecting the fallopian tube,
ischiorectal fossa, cervix, and bladder, as well as similar tumors in the male spermatic cord, scrotum, and perineum [2-6].
The complications with the use of synthetic mesh occur due to its placement adjacent to the bladder and rectum involving extensive paravesical and pararectal dissection includes the passage of needles blindly through the obturator foramen or the
ischiorectal fossa which in turn increase the potential for immediate complications like excessive bleeding, perforation of the bladder, rectum and blood vessels.
In the existing literature, there are several major complications after retropubic MUS, such as nerve, bowel or major vascular injuries, pelvic hematoma, necrotizing fasciitis,
ischiorectal abscess, and even death (26).
