A large and extensive circumferential almost \u2018entirely T2 hyperintense mass lesion\u2019 involving the rectum, anal canal over an approximate length of 11 cm, crossing the anorectal junction demonstrating peripheral heterogeneous enhancement as described \u2013 *of concern for obstructive \u2018Mucinous carcinoma of rectum*\u2019.<\/p>\n
Marked luminal narrowing of the rectum with high grade *large bowel obstruction*.<\/p>\n
The mass is sparing the rectosigmoid junction and terminal 1.8 cm of the anal canal. (distal edge of the mass is 1.8 cm proximal to anal verge). Infiltration of levator ani, proximal anal sphincters.<\/p>\n
Transmural circumferential infiltration involving the entire mesorectal space with evidence of crossing of mesorectal fascia at focal areas.<\/p>\n
Evidence of bilateral fluid distended *perianal fistulous tracts and loss of haustral pattern of the colon – suspicious for underlying inflammatory bowel disease such as Crohn’s disease.<\/p>\n
Multiple enlarged lymph nodes in the perirectal region, sigmoid mesocolon, bilateral internal iliac regions, largest measuring 3.2 x 2.2 cm in the left internal iliac region demonstrating mucin content.<\/p>\n
The anterior margin of the mass lesion is close to the posterior wall of rectum and seminal vesicles, however, no evidence of invasion in this study .<\/p>\n","protected":false},"featured_media":567,"parent":0,"template":"","categories":[],"tags":[],"acf":[],"yoast_head":"\n
