Imaging in the screening and diagnosis of hepatocellular carcinoma in cirrhosis liver in tunisia. a series of 30 cases

The aim of our study is to expose a practical screening and diagnosis strategy of HCC occuring in cirrhosis liver, which is nowadays a health public matter in Tunisia. HCC routine screening in cirrhosis liver has been conducted every 6 months using a combination of abdominal sonography and serum alpha-foetoprotein levels. PCUS, CT scan or MRI have been performed each time a focal liver lesion was discovered in US, or in case of elevated serum alpha-foetoprotein levels. 30 cases of HCC were identified.US has shown a unique nodule in 46% of the cases, multiple nodules in 50% of them. No lesion has been discovered in 4% of the cases. Nodule size ranged from 8 to 140 mm. Heterogenous hyperechoic pattern was the most frequent one [41%]. Hypervascular doppler feature was authentified in 20% of the cases. Serum alpha-foetoprotein levels had respectively a sensitivity and a specificity of 14% and 44% in lesions inferior to 3 cm, 62% and 80% in lesions superior to 3 cm. Typical arterial enhancement of HCC was depicted in 1 case for PCUS, in 76% for CT scan and 60% for MRI. Combination of abdominal sonography and serum alpha-foetoprotein levels practiced every 6 months represent a good compromise between cost and effectiveness. Second intention imaging is based on CT scan in Tunisia because of its availability compared to MRI. PCUS is becoming in the near future the best modality for lesion caracterization thanks to its safety and relative inexpen

[Ectopic testis with mature teratoma. a case report]

Tesicular tumors are rarely seen in childhood. Most teratoma reported to occur in cryptorchid males. The purpose of this paper is to report imaging features of intra-abdominal testis with teratoma in a 4 months-old child admitted to explore abdominal mass. Abdominal ultrasound and CT scan exploration showed a solid mass occuping the right flank including calcified, liquid and fat areas. Surgical exploration found intraabdominal teratoma developed from the right testis

Apport de la TDM dans le bilan d'extension de l'epithelioma malpighien du larynx

The authors report 12 cases of laryngeal carcinoma explored by CT computed tomography at pretherapeutic stage. This study confirms the importance of CT scan which identifies easily, the nature and the extension and orientates a conservative treatment

Exploration echographique de la thyroide propos de 68 cas

High frequence ultrasound contributs largely to the exploration of the thyroid expansive processes. From a retrospective study of 68 cases of diffrent thyroid diseases and a review of literature, the authors specify the interest of ultrasound at diagnostic and therapeutic stages

Mensurations du basin obstetrical par tomodensitometrie [a propos de 110 cas]

We had studied in one year 110 cases of scano- pelvimetry, the clinical examination had not found a shrink pound in 41% revealed by the scenopelvimetry. This method is more precisely than the calssic pelvimetry, but more expansive. The simultaneous study of echography and pelvimetry had contributed to a better obstetrical decision
