CASE 890: CAROTID BODY TUMOR, Dr PHAN THANH HẢI, Dr NGÔ THỊ HUYỀN TRANG, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

 A man with right neck mass for a long time.

 Ultrasound detected a # 28x33x42mm hypervascular mass at the right carotid bifurcation which made it spread out 2 branches of the right carotid artery.

MSCT confirmed a right carotid body tumor.

But the man denied any surgical management.

CASE 889: LEFT COLON TUMOR, Dr PHAN THANH HẢI, Dr NGUYỄN ĐỨC MINH, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

 A 39 year-old man with bloody stool for 5 months and loss of weight.

Ultrasound detected left colon mass which had thickening wall # 11-17mm nearby the spleen and the left kidney.

Colonoscopy and MSCT confirmed the left colon tumor.

Result of biopsy was an adenocarcinoma of colon moderate differentiated.

Endoscopic surgery removed the tumor and metastatic lymph nodes.

CASE 888: LINITIS PLASTICA, Dr PHAN THANH HẢI, Dr NGÔ THỊ HUYỀN TRANG, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

 A 70 year-old infected HCV in hepatic management revealed  12-17 mm malignant lymph nodes nearby the hepatic hilus.

Ultrasound also noted  23-27mm thickening gastric wall and the rigidity of the stomach.

But lab data was no sign of gastroenterologic malignancy.

Later gastroendoscopy confirmed a linitis plastica.

Result of gastric biopsy was a poorly differentiated adenocarcinoma of the stomach.

CASE 884-885-886-887: THYROID FOCAL LESIONS, Dr PHAN THANH HẢI, Dr NGUYỄN TUẤN CƯỜNG, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

 Case A: Cyst of isthmus of thyroid with disseminated crystals, no vascularisation.

Case B: Cyst of left lobe of thyroid reduced  naturally its size in one year.

Case C: Hemorrhagic cyst of left lobe after medical therapeutic management for 5 days: reduced size and clearly septation inside.

Case D:

Focal thyroiditis  non vascular Doppler signal of the right lobe in a Basedow case: painfull but no colored on hypercolored background.

Some ultrasound interesting findings have to know on focal thyroid examination.

CASE 888-889-890: RENAL HYPERPARATHYROIDISM, Dr PHAN THANH HẢI, Dr NGUYỄN TUẤN CƯỜNG, MEDIC MEDICAL CENTER, HCMC VIETNAM.

 Three cases of renal hyperparathyroidism detected by ultrasound.

CASE A:

A woman with hypercalcinosis, renal stones and increasing PTH value but 2 times ultrasound misdiagnosed.

A parathyroid tumor at the upper pole of the left lobe of thyroid later reviewed by ultrasound.

CASE B: 

A 36 year-old man with renal insufficiency on stage 5, PTH high value. Ultrasound detected secondary parathyroid tumors both 2 sides.

CASE C: 

A 46 year-old man with RI and PTH high value due to renal hyperparathyroidism. Ultrasound detected 2 side parathyroid tumors.

Sizes, numbers and structures of renal hyperparathyroidism seem to be not influenced by the blood phosphat and PTH value.

REFERENCE:

 Pathogenesis of secondary hyperparathyroidism in CKD. Progressive loss of renal mass impairs renal phosphate excretion, which causes an increase in serum phosphorus. Abnormalities in serum phosphorus homeostasis stimulate FGF23 from bone. Higher serum FGF23 levels in addition to decreased renal mass cause a quantitative decrease in synthesis of 1,25(OH) 2 D. High serum FGF23 levels decrease the activity of the 1a-hydroxylase enzyme. 1,25 (OH) 2 D deficiency decreases intestinal absorption of calcium, leading to hypocalcemia, which is augmented by the direct effect of hyperphosphatemia. Hypocalcemia and hyperphosphatemia stimulate PTH release and synthesis. The lack of 1,25(OH) 2 D, which would ordinarily feed back to inhibit the transcription of prepro-PTH and exert an antiproliferative effect on parathyroid cells, allows the increased PTH production to continue. Current therapeutic methods used to decrease PTH release in CKD include correction of hyperphosphatemia, maintenance of normal serum calcium levels, administration of 1,25(OH) 2 D analogs orally or intravenously, and administration of a CaSR agonist (e.g., cinacalcet).

CASE 883: INTRAHEPATIC CHOLANGIOCARCINOMA, Dr PHAN THANH HAI, Dr HO TAN ĐAT, MEDIC MEDICAL CENTER, HCMC VIETNAM.

 A  71 year-old woman with a  #40x30mm right lobe hepatic tumor in 3 times of examination.

Ultrasound noted a hemangioma or HCC. MSCT noted a hemangioma in 2 times.And MRI, a cholangiocarcinoma.

Lab data showed  values of AFP, CA 125, CA 19-9 in normal range.

But after a hepatectomy, the surgical specimen of liver tumor was a cholangiocarcinoma.

CASE 882: FETAL HYDROPS, Dr PHAN THANH HẢI, Dr JASMINE THANH XUÂN, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

 A 25 year-old woman with the first normal pregnancy, but in the 21th week there was her fetal hydrops: pleural effusions both two sides, ascites and body edema.

Prenatal ultrasound detected fetal hydrops and helping guided thoracocentesis in 3 times for every  10 days.

At the 25th week, the fetus came back to normal status, no pleural effusion nor ascites and edema.

Amniotic fluid biopsy results no sign of infection. 

And no abnormal structure of the fetus to find out.

The continuity of follow-up are in progress for the case of unknown ascites and pleural effusion of the fetus in a normal pregnancy.
