We present a 57-year-old man with Zollinger-Ellison syndrome who had undergone total gastrectomy 12 years previously. At that time, a cystic mass in the left lobe of the liver was palpated but was not removed. The patient currently had high serum gastrin levels. Abdominal ultrasound, CT and MR images showed a well defined liver mass with solid and cystic(More)
Cystic pancreatic neoplasms include serous cystadenomas (SCA), mucin-producing cystic tumors, cystic islet-cell tumors, and cystic solid and papillary epithelial neoplasms. Imaging techniques are of great value in the demonstration and differential diagnosis of these tumors. In this article we present the computed tomography (CT) and magnetic resonance(More)
Retrorectal-cyst hamartomas (RCH) are rare developmental tail-gut cystic tumours of the retrorectal space, which occasionally undergo malignant transformation. We describe the magnetic resonance imaging (MRI) findings in two patients with RCH and in a third patient with unclassified sarcoma arising from a RCH. The RCH were hypointense or hyperintense on(More)
Vertebral osteomyelitis is one of the most common manifestations of tuberculosis. Magnetic resonance imaging is considered the main imaging modality for the diagnosis, the demonstration of the extent of the disease, and follow-up studies. Vertebral destruction involving two consecutive levels with sparing of the intervertebral disc, disc herniation into the(More)
gangrene. The others were the distal half to two-thirds. The visual findings are striking (Fig. 1). In one, within an hour, the uvular was markedly swollen, deep blue, and congested, evolving into edematous obvious gangrene. This slowly sloughs over a couple of miserable weeks, with the residual ulcer resolving over another week or 2. The hanging mass often(More)
We report a case of a 33-year-old woman with tuberous sclerosis and bilateral angiomyolipomas. She suffered from acute left flank pain due to retroperitoneal haemorrhage. During renal arteriography an arteriovenous shunting was found in the left tumour. Angiomyolipoma is a rare cause of angiographically demonstrable arteriovenous shunting.
In split-liver transplantation, the entire portal flow is redirected through relatively small-for-size grafts. It has been postulated that excessive portal blood flow leads to graft injury. In order to elucidate the mechanisms of this injury, we studied the hemodynamic interactions between portal vein- and hepatic artery flow in an experimental model in(More)
For pancreatic insulinomas, the treatment of choice is surgical excision, which when successful is curative. Intraoperative palpation combined with ultrasonography theoretically depict almost all tumors, however the accuracy of palpation is improved by the preoperative localization. All recent advances in imaging have improved the likelihood for curative(More)
A case of retroperitoneal mucinous cystadenoma histologically confirmed in a 21-year-old woman is reported. Although ultrasound, CT and MR detected the tumor, a preoperative diagnosis could not be established by imaging methods. The cystic tumor was removed and microscopic examination revealed a mucinous cystadenoma. Mullerian mesothelial metaplasia of(More)
