A 51-year-old female with a history of radical mastectomy with axillary lymph node dissection, adjuvant chemotherapy and radiation for a breast cancer was referred to the emergency room due to cholangitis. A CT scan showed a common bile duct mass invading the duodenum. After bile draining, the investigations led to an undifferentiated carcinoma with positive hormonal receptors. The diagnosis of a breast cancer recurrence was established and the patient was commenced on taxane therapy.

Cystic schwannoma represents a neurogenic tumor of the mediastinum rarely reported in literature. Its rupture in the pleural cavity remains exceptional. We hereby report the case of a patient who presented with pleurisy for which diagnostic imaging including thoracic MRI revealed a cystic schwannoma ruptured in the pleura. This case, to the best of our knowledge, represents the very first of its kind reported in literature.

Osteoarticular complications are common after renal transplantation. The complications may result from the bone condition prior to transplantation or the iatrogenic effects of the treatments administered. These complications lead to significant morbidity and mortality, in addition to chronic pain and functional impairment. We report the clinical case of bilateral avascular necrosis (AVN) of the femoral head in a kidney transplant recipient. Clinical Case: 53-year-old male with a history of chronic hypertension. He underwent chronic hemodialysis for 12 months and was treated with Entecavir for chronic hepatitis B. The patient received a kidney transplant from a non-related living donor. Induction therapy included Thymoglobulin along with tapered corticosteroids, reaching a dose of 5 mg/day after 3 months, Mycophenolate mofetil (2 g/day), and Tacrolimus adjusted based on residual levels. There was good recovery of renal graft function. After six months, the patient reported bilateral hip pain and functional impairment of both lower limbs. Pelvic X-rays showed signs suggestive of bilateral AVN of the femoral heads. The diagnosis was confirmed by MRI. The patient underwent right hip drilling and total left hip replacement (THR). A right THR was performed a year later. Conclusion: AVN constitutes a frequent cause of morbidity and mortality after RT. The pathophysiology of osteonecrosis remains complex and multifactorial. We emphasize the importance of conducting a thorough assessment of bone health in patients both before and after RT.

Background: Heart failure is a chronic and severe condition that often results from various heart diseases. Cardiac rehabilitation (CR) is currently a crucial component in managing this condition. The aim was to assess the effects of cardiac rehabilitation on physical capacity of heart failure patients. Methods: This was a cross-sectional study conducted from February 1, 2021, to June 30, 2023. We included all patients with heart failure who underwent cardiac rehabilitation. Data analysis was performed using SPSS software version 24.0, with a significance level set at p Results: The study included 87 heart failure patients, with a male-to-female ratio of 1.8. Mean age was 57.10 years (±11.75). Coronary artery disease was the primary cause of heart failure, accounting for 75.9% of cases. Atrial fibrillation was present in 4.7% of cases. Following cardiac rehabilitation, Left Ventricular Ejection Fraction increased from 40.15% to 49.48% (p = 0.001). Resting heart rate decreased significantly from 81.4 bpm to 68.3 bpm (p = 0.000), and the number of METS increased from 4.3 to 6.57 (+56.8%;p = 0.000). The mean distance covered in the 6-minute walk test significantly increased from 337.8 meters to 522.7 meters (p = 0.000), reflecting a gain of 183.5 meters. Moreover, the increase in the number of METS was more pronounced in females (p = 0.001), non-obese individuals (p = 0.000), non-diabetics (p = 0.001), non-sedentary individuals (p = 0.000), and non-smokers (p = 0.000). The study reported a low readmissions rate of 2.2% and a mortality rate of 1.1%. Conclusion: Our study demonstrates that cardiac rehabilitation is beneficial for black African heart failure patients, resulting in significant improvements in symptoms, physical and capacity.

Congenital cystic dilatations of the bile duct are rare malformations representing 1 per 13,000 births with a female predominance. Diagnosis of this pathology is based on radiological imaging especially radiological investigations conducted on an ultrasound coupled with Computed tomography (CT) scan and especially a bili-MRI which allows the analysis of the bile duct malformations and the anomalies of the pancreaticobiliary junction. We will discuss in this clinical case the various radiological aspects of cystic dilatations of the biliary duct.

Chilaiditi Syndrome

Open Journal of Radiology 2017年第3期7卷 164-169页

The interposition of the colon or the small intestine between the liver and the diaphragm otherwise called Chilaiditi syndrome remains a rare condition. Its incidence varies between 0.025% and 0.28% according to recent literature and is only found incidentally on diagnostic imaging. Hence, it constitutes a classic pitfall in the diagnosis of false right pneumoperitoneum. We deem interesting to report a case of Chilaiditi syndrome in a 44-year-old patient with no significant history who was admitted at emergency department for abdominal trauma following a road accident.

Acute mesenteric ischemia is a serious disease whose prognosis depends on early diagnosis and therapeutic management. Recent imaging technics play a fundamental role in its diagnosis. There are many forms of mesenteric ischemia including the non-occlusive form which is rare among others. We report the case of a non-occlusive mesenteric ischemia by low flow in a patient with terminal renal disease placed on hemodialysis.
