11. Figure 6a. Tumor location in the craniocaudal direction. (a) Illustration depicts the sagittal view of the rectum and provides the measurements of the tumor from the anal
verge, which help categorize tumor location. Blue lines separate the low, mid-, and high rectum. (Figure 6a reprinted, under a CC BY-ND 4.0 license, from Memorial Sloan
Kettering Cancer Center.) (bโd) Sagittal T2-weighted MR images show tumors (arrow) in the high (b), mid- (c), and low (d) rectum. Dotted line = measurement from the
rectum entrance to the tumor location.

Clinical status: A post operative follow-up case of CA rectum.
๏ท Rectum and prostate are not visualized - post surgical status.
๏ท Soft tissue thickening seen at the presacral level.
๏ท Evidence of ill-defined T2 high signal intense irregular marginated lessenhancing solid mass lesion of size measuring ~ 7.9 x 6 x 10.3cm seen at the retroperitoneal region.
๏ท The lesion is seen inferiorlyencasing and compressing the bilateral common iliac arteries and veins.
๏ท Anteriorly and superiorlythe lesion is seen encasing and infiltrating the adjacent bowel loops (small bowel loops), mesenteryand peritoneumand extending to the anterior abdominal
wall through the defect in umbilical level.
๏ท Laterallyand posteriorlythe lesion is seen extending upto the level of colostomy stoma.
๏ท Left mid and distal ureter are infiltrated and encased by the lesion and causing left sided hydroureteronephrosis.
๏ท Posteriorlythe lesion is seen eroding the anterior portion of L5 vertebra.
๏ท The above lesion is showing restricted diffusion.
o Possibility of secondaries/ recurrent mass lesion.
๏ท Minimal free fluid seen at the perihepatic, subdiaphragmatic space and pelvis.
๏ท No evidence of liver and adrenal secondaries.
๏ท Colostomy changes seen at the left iliac fossa.
๏ท Urinarybladder is minimally filled.
๏ท Abdominal aorta and abdominal portion of IVC appearsnormal.

HistoPathology Report
CLINICAL DETAILS :
Known case of Carcinoma rectum recurrence.
Ultrasound guided biopsy from anterior abdominal wall skin deposit.
Clinical suspicion: ? Metastasis.
GROSS :
Received multiple tiny grey white tissue fragments altogether amounting to 0.1 ml. All embedded - 1
block.
MICROSCOPIC FINDINGS :
Sections show fragments of partly hyalinized fibrous connective tissue with pools of extracellular PASD+
mucin. Occasional small clusters, strips and possibly fragmented glands lined by columnar cells, including
cells resembling goblet cells with PASD+ vacuolated cytoplasm, exhibiting mild to focal moderate nuclear
pleomorphism are seen within the mucin pools. Occasional muciphages are also noted. Deeper levels
have been examined.
IMPRESSION :
SCANTY ULTRASOUND GUIDED BIOPSY FROM ANTERIOR ABDOMINAL WALL SKIN DEPOSIT
WITH EXTRACELLULAR MUCIN POOLS AND SCATTERED ATYPICAL COLUMNAR CELL
CLUSTERS.
NOTE: HISTOLOGICAL FEATURES IN THIS SCANTY BIOPSY ARE SUSPICIOUS OF METASTATIC
MUCINOUS CARCINOMA. SUGGEST CLINICO-RADIOLOGICAL CORRELATION AND REPEAT
BIOPSY, IF NECESSARY.
