CASE 519: LYMPHOMA in RETROPERITONEUM, Dr LY VAN PHAI, Dr PHAN THANH HAI, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

WOMAN 51 YO WITH  LUMBAGO, PAIN IN RIGHT LEG FOR  3 MONTHS. 
X-RAYS OF LUMBAR SPINE IS NORMAL.

ULTRASOUND  DETECTED  RETROPERITONEAL HYPOECHOIC MASS   COVERING  THE RIGHT PSOAS MUSCLE.
US1 = LONGITUDINAL SCAN OF RIGHT PSOAS MUSCLE  HYPOECHOIC LIKE CYST.

US 2  = PSOAS MUSCLE IS BEING PULL UP ;  US 3  = AVASCULAR HYPOECHOIC AREA ; US 4,  US 5  = BENDING AORTA  AND ILIAC ARTERY .

MSCT CE = CT 1 :CROSSED-SECTION NON CE: THIS MASS  PARAVERTEBRAL; CT 2 : CROSSED- SECTION AT PELVIS  CT3, CT4 : FRONTAL VIEW OF  THIS MASS WITH VERY HIGH CE ENHANCEMENT,  ILIAC ARTERY DEPLACED AND PSOAS MUSCLE  IS  INTACT.

MRI  WITH GADO =  MRI 1:CROSSED- SECTION VIEW, THIS MASS IS SOLID,  PULL UP THE ILIAC ARTERY;   MRI 2 : CROSSED- SECTION AT PELVIS

MRI 3 : FRONTAL VIEW;   MRI 4 : SAGITTAL VIEW,  PSOAS MUSCLE IS ENROUNDED BY TUMOR.

MRI contrast got down intra urinary bladder  looks like a  picture of camel.

MRI 5:  sagittal view of lumbar spine  shows the tumor invaded to spinal canal.

BLOOD TESTS= WBC, CRP ARE NORMAL, MARKER  BETA2 MICROGLOBULINE, LDH, FERRITIN ARE IN NORMAL  LEVELS.

RADIOLOGIST SUGGESTION IS RETROPERITONEAL LYMPHOMA.

BIOPSY WAS DONE .

RESULT OF HISTOLOGY WITH IMMUNO-HISTO -CHEMISTRY  IS  LYMPHOMA B SMALL CELL.

CASE 518: FINGER TUMORS, Dr PHAN THANH HẢI, Dr NGUYỄN NGHIỆP VĂN, Dr TRẦN THỊ THANH NGA, Dr LÊ THÔNG LƯU, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

Woman 20yo with right hand  having many tumors at fingers,  slow growth, difficult movement of flexion ( see foto   (right hand  dorsal view:   tumor at first finger, finger number 3  and  number 5)  color skin  is changed,   soft in palpation and  no pain.

Ultrasound of  this tumor by linear probe 11 MHz : US 1:  tumor solid  hypoechoic, ellypsoid ;
 2 -3cm, central necrosis; crossed section ( US 2 ) with more vascular supplying and not fixed to bone.

Another tumor only in right hand not related to joint .

Clinical history: she was being treated in hospital as  hemangioma,   but  sonologist said  it is geant cell tumor of the tendon sheath.

X-Rays films of the right hand: No erosion of the bone.
Abnormal atrophic metatarsal number 4. Typical cavernous hemangioma and phleboliths.

MRI OF RIGHT HAND   SHOWS MULTIPLE TUMORS.

Operation removed one small tumor at first finger.

Histology report is benign capillary hemangioma, perycyte hemangioma of fingers.

CASE 517: HCC WITH LOW AFP, Dr PHAN THANH HẢI, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

MAN 52 YO with HBV INFECTED and   EPIGATRIC PAIN.   

ULTRASOUND CHECK UP DETECTED  LEFT LIVER TUMOR, SIZE 3.5 CM   HYPOECHOIC (US1,US2  )   BLOOD TETS: HBsAg POSITIVE, AFP 15ng/mL.

CT SCAN LIVER =  CT 1  NON CE , CT2, CT3   TRIPHASES CE , CT4 FRONTAL VIEW , CT5  SAGITTAL VIEW.

RADIOLOGIST REPORT IS  HCC.

MRI PRIMOVIST = MRI 1 DWI ,  MRI 2  T1, MRI 3 GADO INPUT,   MRI 4 GADO OUT,   MRI 5  FRONTAL VIEW.

BLOOD TEST AGAIN=  WAKO TEST  AFP-L3  RISING 16.4 %.

SUMMARY=  MAN 52 YO HBV INFECTED
WITH AFP NEGATIVE   BUT ULTRASOUND DETECTED TUMOR AND CT CE , MRI GADO   STUDYING THIS TUMOR.   WAKO TEST IS  POSITIVE  WITH L3 RISING. HOW ACCURATE DIAGNOSTIC OF   ALL FACILITIES?

OPERATION IN THE PLAN of LEFT HEPATECTOMY.

Robotic operation for  left hepatectomy.   See  macro  tumor with white area.

Microscopic with histo immunostaining  is  undiffentiated HCC.

CASE 516: PANCREAS TUMOR, Dr PHAN THANH HAI, Dr TRUONG DINH KHAI, MEDIC MEDICAL CENTER, HCMC, VIETNAM

Girl  10yo with  epigastric pain.

Ultrasound of abdomen detected  one mass of 8cm  at the body of pancreas, cystic  structure,  well bordered  ( US 1,  US 2, US 3),  no lymph node around.

MSCT with CE=   this mass is from the tail of pancreas,  inhomogeneous structure (CT1 CT 2, CT 3).

Blood tests  are normal.

Operation for resection of this tumor  [see macro].

CT  SHOWS THIS TUMOR A SOLID TUMOR BUT ULTRASOUND SCAN FINDING IS CYSTIC.

Summary:  Girl 10 yo  with big mas at the pancreas,  structure is mixed solid and cystic,  the most common  is  solid pseudocystic papillary tumor.
