1/405. An extrahepatic bile duct metastasis from a gallbladder cancer mimicking Mirizzi's syndrome.We report a case of an extrahepatic bile duct metastasis from a gallbladder cancer that mimicked Mirizzi's syndrome on cholangiography. A 67-yr-old woman was admitted to our hospital with a diagnosis of acute calculous cholecystitis. As obstructive jaundice developed after the admission, percutaneous transhepatic biliary drainage was performed to ameliorate the jaundice and to evaluate the biliary system. Tube cholangiography revealed bile duct obstruction at the hepatic hilus, and extrinsic compression of the lateral aspect of the common hepatic duct, with nonvisualization of the gallbladder. No impacted cystic duct stone was visualized on CT or ultrasonography. laparotomy revealed a gallbladder tumor as well as an extrahepatic bile duct tumor. We diagnosed that the latter was a metastasis from the gallbladder cancer, based on the histopathological features. This case is unique in that the extrahepatic bile duct metastasis obstructed both the common hepatic duct and the cystic duct, giving the appearance of Mirizzi's syndrome on cholangiography. Metastatic bile duct tumors that mimic Mirizzi's syndrome have not been previously reported. The presence of this condition should be suspected in patients with the cholangiographic features of Mirizzi's syndrome, when the CT or ultrasonographic findings fail to demonstrate an impacted cystic duct stone.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
2/405. Gross hematuria of uncommon origin: the nutcracker syndrome.Left renal vein hypertension, also called "nutcracker phenomenon" or "nutcracker syndrome," is a rare vascular abnormality responsible for gross hematuria. The phenomenon is attributable to the idiopathic decrease in the angle between the aorta and the superior mesenteric artery with consequent compression of the left renal vein. The entrapment of the left renal vein is not easily detectable by ordinary diagnostic procedures. We report two cases of gross hematuria (persistent in one patient and recurrent in the other) caused by "nutcracker phenomenon." In both cases, no remarkable findings were obtained from medical history, urinary red blood cells morphology, repeated urinalysis, pyelography, cystoscopy, or ureteroscopy. Left renal vein dilation in one case was found with a computed tomography (CT) scan performed on the venous tree of left kidney. The diagnosis of "nutcracker phenomenon" was confirmed by renal venography with measurement of pressure gradient between left renal vein and inferior vena cava in both cases. In one case, the diagnosis was complicated by the presence of mycobacterium tuberculosis in urine. The "nutcracker phenomenon" is probably more common than thought. early diagnosis is important to avoid unnecessary diagnostic procedures and complications such as the thrombosis of the left renal vein. Many procedures are available to correct the compression of the left renal vein entrapped between the aorta and the superior mesenteric artery: Gortex graft vein interposition, nephropexy, stenting, and kidney autotransplantation. After surgery, gross hematuria ceases in almost all patients.- - - - - - - - - - ranking = 2keywords = compression (Clic here for more details about this article) |
3/405. Musculoskeletal manifestations of the Antley-Bixler syndrome.The Antley-Bixler syndrome is a rare disorder with many musculoskeletal anomalies that demand orthopedic assessment. The syndrome includes skeletal, craniofacial, and urogenital anomalies. The most common skeletal deformities are radiohumeral synostosis, craniosynostosis, multiple joint contractures, and arachnodactyly. Other orthopedic manifestations that may occur are femoral bowing, ulnar bowing, camptodactyly, synostoses of carpal and tarsal bones, clubfoot, vertebral body anomalies, perinatal fractures, and advanced skeletal age. The inheritance pattern is thought to be autosomal recessive. A patient with this syndrome is described, which is the 18th of 24 reports published in the world literature. This case is compared with the other reported cases.- - - - - - - - - - ranking = 0.33196020238391keywords = fracture (Clic here for more details about this article) |
4/405. Transverse stress fracture of the patella in a child.Transverse stress fracture of the patella in a child is an exceptional injury in childhood. Only one case has been previously reported. The present study reports a new case of a 12-year-old boy with anterior knee pain misdiagnosed for 5 months as Sinding-Larsen-Johansson disease who developed sudden anterior right knee pain and pop while running in a soccer match. Surgery was performed. The evolution was favorable without any immobilization required and the patient achieved full recovery.- - - - - - - - - - ranking = 1.6598010119196keywords = fracture (Clic here for more details about this article) |
5/405. mirizzi syndrome--a report of 3 cases with a review of the present classifications.We report three cases of mirizzi syndrome, two with external compression of the common hepatic duct and another with cystobiliary fistula. All patients presented with jaundice. The diagnosis was suggested by ultrasonography and confirmed by endoscopic retrograde cholangiography (ERC). All three had the stones removed surgically, one through a choledochotomy, another through an opening in the gall bladder and the third at the time of subtotal cholecystectomy. We would like to propose a simple classification of mirizzi syndrome, based on surgical procedures necessary for the correction of the pathological anatomy. If it involves the removal of calculi with some form of cholecystectomy, we consider it as Type I, whereas Type II involves the construction of a hepaticojejunostomy apart from the removal of calculi.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
6/405. Marked increase in flow velocities during deep expiration: A duplex Doppler sign of celiac artery compression syndrome.Symptoms of chronic mesenteric ischemia develop when the celiac artery is constricted by the median arcuate ligament of the diaphragm. Lateral aortography is the primary modality for diagnosing ligamentous compression of the celiac artery. However, duplex Doppler sonography performed during deep expiration can cause a marked increase in flow velocities at the compressed region of the celiac artery and suggest the diagnosis of celiac arterial constriction due to the diaphragmatic ligament.- - - - - - - - - - ranking = 5keywords = compression (Clic here for more details about this article) |
7/405. mirizzi syndrome: A rare cause of obstructive jaundice.mirizzi syndrome is a rare cause of bile duct obstruction secondary to extrinsic compression of the hepatic duct by stones impacted in the cystic duct or infundibulum of the gallbladder. The suspicion of mirizzi syndrome primarily relies on radiographic means such as ultrasound, computed tomography and cholangiography. The recognition of this rare syndrome is crucial in developing the proper treatment approach. We present 3 cases of mirizzi syndrome and a review of the literature pertaining to the diagnosis and treatment of this rare cause of obstructive jaundice.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
8/405. Painless aortic dissection presenting as hoarseness of voice: cardiovocal syndrome: Ortner's syndrome.Most of the neurological manifestations of the aortic dissection are due to neuronal ischemia secondary to either extension of the dissection process into a branch artery, or compression of an artery by the false lumen of the dissecting aortic hematoma. However, the enlarging false lumen may directly compress on an adjacent nerve, causing neuronal injury resulting in neurological symptoms. This may particularly take place when a distal intimal tear does not decompress the false lumen, resulting in formation of an expanding blind pouch. About 10% of aortic dissections are painless and may present with symptoms secondary to the complications of the dissection. Although cardiovocal syndrome, or Ortner's syndrome (hoarseness of voice due to involvement of recurrent laryngeal nerve in cardiovascular diseases) has been described with aortic dissection, it has not been reported as an initial presenting feature of this disorder. This report describes the first case of painless aortic dissection presenting with hoarseness of voice, the cardiovocal syndrome. The hoarseness remained the only symptom throughout the entire course of the disease. The aortic dissection was not suspected initially. During surgical exploration, the recurrent laryngeal nerve was found compressed by the false lumen at the level of aortic arch. Aortic root replacement was performed successfully, resulting in complete resolution of the hoarseness. The neurological manifestations of aortic dissection, and the cardiovocal syndrome, are discussed.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
9/405. Quadrangular space syndrome associated with superficial radial sensory neuropathy.Compression of the axillary nerve in the quadrangular space is an unusual cause of pain and paresthesia of the upper extremity. In this report, the authors present a patient with a 1-year history of an undiagnosed axillary nerve compression associated with radial sensory neuropathy who improved after surgical decompression of the quadrangular space.- - - - - - - - - - ranking = 2keywords = compression (Clic here for more details about this article) |
10/405. Brugada-like electrocardiographic pattern in a patient with a mediastinal tumor.We report on a patient with a mediastinal tumor and electrocardiographic findings similar to those described in the brugada syndrome. This peculiar ECG pattern disappeared after tumor removal, thus suggesting it was probably caused by compression of the right ventricular outflow tract by the mass.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
