CASE 597: RECTUM CANCER, Dr PHAN THANH HẢI, Dr PHAN ANH TUẤN, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

Male patient 60yo with lower GI tract hemorrhagia for months. At local hospital rectal endoscopy noted rectal wall rigid invasion. Biopsy results showed rectal ulcerative inflammation with anaplastic inversion. 







At Medic Center, colon enema with barium revealed contrast lacunae and rigid wall of rectal   tumor.        





Abdominal MSCT= Rectal wall lesion thickening #18mm captured contrast in medium intensity and degraded fatty tissue around . Some mesenteric  nodes 5-10mm. Being thought about rectal tumor invading tissue around and metastasing to nodes.

-                    


-                   Pelvic MRI= Invaded pattern tumor  is inside rectum # 82mm  which made narrowing rectal  lumen that is far from anus #46mm and invaded muscular layer toward posterior wall of rectum and presacral area from S2 to coccyx and adhered  posterior prostatic urethra wall. Gado captured non similarly with high signal intensity on T2W1, medium signal intensity on T1W1. Some 10-16mm nodes existed around rectum.




-                   Intraluminal rectal ultrasound with probe ASU-67, 7.5-10MHz,  views 360 degree detects rectal tumor far from anus 30-40mm. Tumor takes place entirely rectum and outside = invaded anterior sacrum posteriorly and adhered prostate and prostatic urethra anteriorly. Existing some 5-7mm nodes nearby tumor.







-                   Endoscopy of rectum revealed rectal ulcerative invasive lesions that made narrowing rectal lumen. Biopsy results is poor differentiated adenocarcinoma, type ring cell of rectum.




Chemotherapy is on going for patient at Binh dan hospital.                     

 CONCLUSION=

Intraluminal rectal ultrasound by probe view 360 degree is useful to assess rectal wall lesion and around rectum tissue,  taking part to detect rectum and rectal canal disorders.

CASE 596: SEVERE STENOSIS ILIAC ARTERY, Dr PHAN THANH HẢI, Dr NGUYỄN NGHIỆP VĂN, Dr VÕ NGUYỄN THÀNH NHÂN, Dr VÕ HIẾU THÀNH, Dr HỒ KHÁNH ĐỨC, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

Male patient, 51yo, from Kien giang province,  with asthenia of right leg in walking about a distance of 100 meter.
At Medic Center, vascular ultrasound revealed aliasing spectrum of  right common iliac artery in stenosis # 80% due to atherosclerosis.


Right common femoral artery shows Doppler spectral biphasic pattern.


Right pedial artery with tardus parvus pattern and decreasing severely of arterial flow.


CT Angio later comfimed diagnostic.





Transferred to Binh Dan hospital, by via DSA, patient went to arterial dilatation and stenting to recover flow of root of right common iliac artery.

DSA before arterial dilatation= Confirmed diagnostic of 80% stenosis of right iliac artery root.


After arterial dilatation and stenting= Well recovered arterial flow, and no more arterial stenosis on controlled film.



Patient remains well and discharged in healthy status one day later.

CONCLUSION: Atherosclerosis causes severe stenosis #80% of right common iliac artery which had been rapidly diagnosed, and safety of management by arterial dilatation and stenting. Only one day lasting for treatment in hospital, patient finely discharged without intermittent claudication symptom.

CASE 595: HCC WITH NEGATIVE WAKO TEST, Dr PHAN THANH HẢI, MEDIC MEDICAL CENTER,HCMC,VIETNAM

Male patient 58yo, with HCV infection that had been treated by interferon for several months.

In check-up, ultrasound detected one round mass # 3cm look like a cyst.


WAKO tests= AFP=5.7, L3= 0.5, DCP=16.

MSCT with CE detected non tumor.



Gado MRI of  liver reported HCC.

MR image shows a lesion in hepatic segment V; with the size 24mm, well-defined. The lesion demonstrates high signal intensity on T2WI and low signal intensity on T1WI.

The lesion had restricted on Diffusion Dynamic MRI: On arterial phase image demonstrates unequivocal arterial enhancement relative to the surrounding liver; On the portal venous phase has decreased in enhancement relative to the surrounding liver (washout); On the delay phase has decreased in enhancement relative to the surrounding liver and enhance capsule is found which helps further solidify the imaging diagnosis of HCC.

-This patient has negative Wako test. Volk et al (2007) and Hann et al (2013) demonstrate of  Wako test with sensitivity (83%) and specificity (>90%) for detecting HCC.






Operation removed the liver tumor.



 Histopathologic report= HCC well-differentiated.
