CASE 493: THYROID SMALL PTC, Dr PHAN THANH HẢI, MEDIC MEDICAL CENTER, HCMC, VIETNAM

Woman 52 yo, thyroid ultrasound screening detected 2 small nodules of left thyroid gland  in  2015. But now in 2018,  sonologist reported back them being in TI-RADS 5, size=3.5mm. FNCA   made sure that PTC.

Operation is subtotal thyroidectomy.

   

See  macroscopic specimen pictures.

Microscopic report post op made sure again PTC.

CASE 492 : APPENDICULAR MUCOCELE, Dr PHAN THANH HẢI, Dr TRẦN NGÂN CHÂU, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

Man 65 yo with abdomen distention (photo). For 40 years he underwent a laparotomy in emergency by gunshot.

Ultrasound of abdomen detected at pelvis  one round bordered mass,  size of  20cm. Its structure looked like cyst with many ring layers as an onion skin sign.

US 1: crossed- section at middle abdomen;  US 2 : with CDI,  mass no vascular inside; US 3:  longitudinal scan over aorta; US 4:  multiple ring layers as onion skin sign; US 5 : with  linear probe.

MSCT  scan with  CE : CT 1: this mass is cystic formation from the coecum; CT 2 : frontal view.

Appendicular mucocele  was made for  diagnosing of the pelvic mass. Operation removed one mass with mucus content from appendix.

CASE 491: TOOTHPICK MOVING TO RETROPERITONEUM, Dr PHAN THANH HẢI, MEDIC MEDICAL CENTER, HCMC, VIETNAM

Man 60 yo with  epigastric pain  one month ago; in  emergency CT of abdomen detected    a  foreign body ( FB) looked like a toothpick penetrating duodenum D2 wall.

But gastroscopy and colonoscopy cannot find  out this foreign body (FB). And  so  do laparoscopy later.

At Medic center,  ultrasound again detected this foreign body (FB) in retroperitoneum  near IVC and aorta (US 1. US 2), very strong shadowing , US 3: longitudinal  FB # 5 cm).

MSCT of abdomen  non CE   (CT1:  crossed section  this FB near aorta , CT 2 : frontal view , CT 3:  3 D view).

Gastroscopic laparoscopy again removed this  toothpick # 5 cm at the wall of D2.

Conclusion : Toothpick  can move to retroperitoneum.

CASE 490: ANECHOIC CRESCENT' S SIGN OF AORTA DISSECTING, Dr PHAN THANH HẢI, MEDIC MEDICAL CENTER, HCMC, VIETNAM

Man 34 yo, now  epigatric pain  with history of  operation for repairing aortic valve since 2008.

Ultrasound of abdomen detected abnormal aorta.          

US 1  crossed- section   aortic  size 3 cm   with anechoic crescent in lumen of aorta

US 2  longitudinal scan  with  Doppler dual gates=  aorta had double  flows in aorta in turbulence.

US 3  video

Ultrasound suspected   dissection of  abdominal aorta

MSCT angio: 

CT 1   crossed section near aortic valve.

CT 2  crossed section over cross aortic   also see “crescent sign" of the wall of aorta,  with double lumen.

CT 3  frontal view.

CT4   full aortic tree =aortic dissection.

Summary:   Anechoic crescent sign in ultrasound or CT of  aortic dissection.

CASE 489: LOST OF CONTRACEPTIVE IMPLANT, Dr PHAN THANH HAI, Dr LE THONG NHAT, Dr LE THONG LUU, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

WOMAN  31 YO  HAD BEEN PUT ACONTRACEPTIVE IMPLANT AT THE LEFT BRACHIAL AREA 3 YEARS AGO, BUT NOW THE OB-GYN HOSPITAL CANNOT FIND OUT THE DEVICE FOR REMOVING IT.

 AT MEDIC CENTER, X-RAYS FOUND THIS IMPLANT STILL NEAR THIS PLACE (X-RAY FILM).

ULTRASOUND DETECTED  IT IN BICEPS MUSCLE  ( US 1, US 2 ).

OPERATION REMOVED THE INTRAMUSCLE DEVICE  (PHOTO).

CONCLUSION : CONTRACEPTIVE IMPLANT CAN MOVE  TO ANOTHER SITE POST IMPLANTATION.

REFERENCE   CONTRACEPTIVE IMPLANT MOVE TO THE LUNG.

CASE 488: CT SCANNING INCIDENTAL DIAGNOSIS of RECTUM CANCER, Dr PHAN THANH HẢI, MEDIC MEDICAL CENTER, HCMC, VIETNAM

Woman 79 yo  being treated  right kidney stone.  3 years ago, with  ultrasound of abdomen in  black and white images   detected a stone with size 1 cm (US 1, US 2   longitudinal scan and crossed  section of right kidney).

On color Doppler  it exists an AVM  with calcification ( US 3, US 4).

MSCT with CE of abdomen  for   sure  AVM  of right kidney (CT 1,CT 2, CT 3, CT 4, CT 5) , radiologist reported at  CT 3 image  one mass  at  pelvis  like  sigmoid colon  tumor.

Coloendoscopy  confirmed that  rectum tumor  # 16 cm, high from anus.

Biopsy on the way (endoscopic image)

MRI  preop  takes staging of rectum cancer T4 N1 Mx.

Conclusion: Abdomen CT for  diagnosing AVM of right kidney detected incidentally a rectum cancer on AVM and stone kidney patient.

Operation  for  resection of rectum tumor and reanastomosis by stappler (MACRO ).

MACROSCOPIC  REPORT  IS  ADENOCARCINOMA  OF RECTUM.

SUMMARY  = CTA  IS THE BEST DIAGNOSING MODALITY for RENAL AVM  at THE SAME TIME  OF INCIDENTAL DIAGNOSING FOR RECTUM CANCER  WHICH WAS MISTAKED BY ULTRASOUND.
