SPRINGFIELD IMAGING CENTER
CT Chest, Abdomen, and Pelvis with IV Contrast
Patient: Robert Chen
MRN: MRN003
Date of Exam: March 18, 2024
Ordering Provider: Dr. Michael Anderson
Indication: Staging of newly diagnosed sigmoid colon adenocarcinoma
TECHNIQUE:
CT of the chest, abdomen, and pelvis was performed following administration of
intravenous contrast. Oral contrast was not administered due to concern for
partial obstruction.
FINDINGS:
CHEST:
Lungs: Multiple bilateral pulmonary nodules are identified. Largest nodule in
the right lower lobe measures 1.2 cm. Additional smaller nodules measuring
4-8 mm are seen throughout both lung fields. Appearances are highly concerning
for metastatic disease.
Heart: Normal size. No pericardial effusion.
Mediastinum: No significant lymphadenopathy.
Pleura: No pleural effusion.
ABDOMEN:
Liver: Multiple hypodense lesions throughout the liver consistent with metastases.
Largest lesion in segment 7 measures 4.2 cm. Additional lesions range from 1-3 cm.
Total of 8 discrete lesions identified.
Spleen, Pancreas, Adrenals: Unremarkable.
Kidneys: Normal size and enhancement bilaterally. No hydronephrosis.
Colon: Circumferential wall thickening in the sigmoid colon with associated
fat stranding. The thickened segment measures approximately 6 cm in length.
No evidence of perforation or obstruction at this time.
Peritoneum: No ascites. No peritoneal implants identified.
Lymph Nodes: Enlarged lymph nodes in the sigmoid mesocolon, largest measuring
1.8 cm, consistent with regional nodal metastases.
PELVIS:
Bladder, Prostate, Rectum: Unremarkable.
Pelvic lymph nodes: No significant pelvic lymphadenopathy.
BONES:
No suspicious lytic or blastic lesions. No pathologic fractures.
IMPRESSION:
1. Primary sigmoid colon mass consistent with known adenocarcinoma, measuring
approximately 6 cm in length with regional lymphadenopathy.
2. Multiple hepatic metastases, largest 4.2 cm in segment 7.
3. Multiple bilateral pulmonary nodules highly suspicious for metastatic disease.
4. Findings consistent with Stage IV (T3 N2 M1b) colorectal carcinoma.
RECOMMENDATIONS:
Clinical correlation recommended. Consideration for systemic chemotherapy.
Biopsy of hepatic lesions may be considered if diagnosis confirmation needed,
though imaging findings are typical for metastatic disease.
