Study reveals,
· There is 14.6x10.6x12.1 cm sized (APxMLxSI) large, heterogenously enhancing, solid cystic lesion noted in pelvis. Few non enhancing areas are noted within this lesion s/o necrosis/cystic changes. Few foci of calcifications are noted within this lesion. Bilateral ovaries are not separately seen from this lesion. This lesion is seen infiltrating the distal aspect of body of uterus and cervix with resultant endometrial collection in fundus of size 7.2X11.2X9.4 cm (APxMLxSI). It is seen causing mass effect on both lower ureters with resultant fullness of bilateral pelvicalyceal system. Fat planes of this lesion with adjacent small bowel loops, sigmoid colon and rectum appear indistinct at most of the places. However no significant dilatation of proximal bowel loops seen. Anteriorly, this lesion is seen indenting the posterior wall of urinary bladder and further extending upto the anterior abdominal wall with loss of fat plane at few of the places. Laterally, fat planes with bilateral psoas muscle are lost at few places.
· Few heterogenously enhancing soft tissue mesenteric and omental deposits are seen. Similar appearing soft tissue deposits are also seen along the anterior abdominal wall in infraumbilical region in midline. Largest lesion measures 4.3x.4.6X3.8 cm (APxMLxSI) in size.
· Abnormal nodular enhancement of peritoneal lining is seen.
· Liver appears enlarged, measures 16.7cm. Few tiny ill-defined hypoenhancing lesions are noted along segment V/VI/VII/VIII of liver with associated scalloping of liver surface.
· Gall bladder is distended with normal wall thickness.
· Pancreas appears normal and shows normal contrast enhancement. CBD appears normal.
· Spleen is normal in size. Multiple heterogenously enhancing hypodense lesions are noted involving lower pole of spleen with largest measuring 4.5X3.9X2.5 cm (APxMLxSI). Scalloping of splenic and liver parenchyma is seen at places.
· Aorta, IVC, portal vein SV, SMV and SMA appears normal. Both adrenals are normal.
· Both kidneys appear normal in size and shows prompt nephrogram and good excretion of contrast. Hyperdense calculus of size 1.1x 0.7cm is noted at mid pole of right kidney with average CT value of 500-600HU.
· Gross free fluid is noted in abdomen and pelvis. Visualised lung parenchyma appears normal.
· Visualized bones show degenerative changes in the form of marginal osteophytes and end plate changes.
· Grade I anterolisthesis of L5 over S1 vertebra with bilateral spondylolysis and vaccum phenomenon is noted.
· Atherosclerotic changes are noted in visualised abdominal aorta in the form of wall calcification
Impression:
· Large, heterogenously enhancing, solid cystic lesion in pelvis with morphology, relations and extensions as described above s/o malignant neoplastic etiology- most likely mucinous neoplasm of ovarian origin. Suggested Histopathological Correlation.
· Multiple omental, mesenteric, peritoneal and anterior abdominal wall deposits as described above s/o metastasis.
· Splenic and liver metastasis as described above.
· Gross ascitis with subtle scalloping of liver and splenic parenchyma as described above.
· Non obstructive right renal calculus.
