Abdominal wall malformations correspond to a wide spectrum of congenital anomalies that are due to a defect in the closure of the anterior abdominal wall and can be fatal. We report the case of laparoschisis associated with a poly malformation syndrome in the same fetus at the reference health center of commune III of the district of Bamako. The objective is to clarify the interest of antenatal ultrasound in the diagnosis and prognosis of these malformations. It was a 19-year-old prim gravid woman received as part of the prenatal check-up. Antenatal ultrasound had allowed the diagnosis of malformation of the anterior abdominal wall of the gastroschisis type associated with abnormalities of the neural tube, the urogenital system and the bone skeleton. The antenatal diagnosis of the malformations had motivated the realization of a therapeutic termination of pregnancy at 19 weeks of amenorrhea and 3 days by triggering and vaginal delivery, allowing the confirmation of the diagnosis of gastroschisis and the poly malformation syndrome which is extremely rare. Antenatal ultrasound remains an ideal means of imaging for monitoring pregnancy and had made it possible to make the prognosis and antenatal diagnosis of multiple malformations in association, and to indicate better therapeutic decision-making.

Amide proton transfer (APT) magnetic resonance imaging (MRI) is an important molecularimaging technique at the protein level in tissue. Neurodegenerative diseases have a highlikelihood of causing abnormal protein accumulation in the brain, which can be detectedby APT MRI. This article briefly introduces the principles and image processing technologyof APT MRI, and reviews the current state of research on Alzheimer's disease and Parkinson's disease using this technique. Early applications of this approach in these twoneurodegenerative diseases are encouraging, which also suggests continued technicaldevelopment and larger clinical trials to gauge the value of this technique.

With technological advances in laparoscopic hepatectomy and new navigation devices,such as flexible laparoscopic ultrasound probes,indocyanine green(ICg)-fluorescent imaging and three-dimensional imaging,laparoscopic segmentectomy(LS),which maximizes the preservation of the functional hepatic reserve and the possibility for future repeat hepatectomy while ensuring adequate surgical margins,has become a feasible alternative to hemihepatectomy for addressing hepatocellular carcinoma(HCC).
