Methods: during the research period from January 2020 to January 2022, 66 children with non traumatic acute abdomen were taken as the research sample data to explore the diagnostic intervention methods and analyze their clinical application effects. 66 children with non traumatic acute abdomen were diagnosed by color Doppler ultrasound, and compared with pathological diagnosis as the "gold standard", The disease detection rate (acute appendicitis, mesenteric lymphadenitis, intestinal obstruction, intussusception and cholecystitis) was analyzed. Results: after pathological diagnosis, 25 cases of acute appendicitis (25 / 66, 37.88%), 8 cases of mesenteric lymphadenitis (8 / 66, 12.12%), 11 cases of intestinal obstruction (11 / 66, 16.67%), 13 cases of intussusception (13 / 66, 19.69%) and 9 cases of cholecystitis (7 / 66,13.64%) were detected;Under the diagnosis of color Doppler ultrasound, 25 cases of acute appendicitis (25 / 66, 37.88%), 7 cases of mesenteric lymphadenitis (7 / 66,10.61%), 11 cases of intestinal obstruction (11 / 66,16.67%), 13 cases of intussusception (13 / 66, 19.69%), 7 cases of cholecystitis (7 / 66, 10.61%), the diagnostic accuracy rate was 63 / 66 (95.45%), and the misdiagnosis and missed diagnosis rate was 3 / 66 (4.55%), (2= 3.0698, P = 0.0798.Conclusion: the application of color Doppler ultrasound in the clinical diagnosis of children with non traumatic acute abdomen has significant diagnostic effect. It can timely determine the disease types of children with non traumatic acute abdomen and avoid missed diagnosis and misdiagnosis, which is worthy of clinical application.展开更多

It is a very common pathology, the diagnosis of which is mainly clinical. However, magnetic resonance imaging occupies an essential place in the site diagnosis and etiological research in the management. Non-traumatic spinal cord compression is a diagnostic and therapeutic emergency, requiring early and appropriate management. MRI is the benchmark imaging examination for this pathology. No similar previous MRI study in Mali. We undertook this work with the aim to determine the place of MRI in the diagnosis of spinal cord compressions in Mali hospital. <strong>Method and Patients:</strong> This was a descriptive retrospective study, carried out at the hospital’s medical imaging department from January 1, 2017 to December 31, 2018 (02 years). It involved all patients, regardless of sex and age, sent for an MRI examination of the spine, and in whom spinal cord compression was diagnosed. We used a 0.35T low-field MRI machine with solid-state antennas. <strong>Results:</strong> We collected 179 cases of spinal cord compression MRI out of 585 spinal MRI performed, (frequency of 30.59%). The average age was 53.5 years with a male predominance (sex ratio 3.7). Motor disorders were the most common reason for examination (41%). We used the T1 T2 sagittal and T2 axial sequences. IV injection of gadolinium was performed in 48% of patients. The topographic lesions were: cervical (54.7%), thoracic (31.3%) and several segments (9.5%). The lesions concerned the compartments: extradural (79.3%), intradural (4.5%), and intramedullary (16.2%). The processes were degenerative (57.5%). tumorous (29.6%), infectious (12.3%) and vascular (0.6%). <strong>Conclusion:</strong> MRI is the benchmark imaging test for the management of non-traumatic spinal cord injury. Myelo-CT can be an alternative in the absence or in case of MRI contraindication.展开更多

Many variations in its origin and course have been observed;however, as far as we know, the association of true aneurysm of the PMA and its anomalous origin from the internal carotid artery has not been reported previously. We reported the case of a 59-year-old woman who suddenly presented a loss of consciousness without head trauma, computed tomography (CT) revelated intracerebellous hematoma associated with a subarachnoid hemorrhage of the posterior cerebral fossa. Cerebral angiography demonstrated a true aneurysm of the PMA which originated from the internal carotid artery.展开更多
