We present a case of stent-assisted coil embolization of a wide-necked renal artery aneurysm performed at our institution. The technique involved a stent being delivered over the neck of the aneurysm. Subsequently a catheter was placed into the aneurysm through the stent mesh and the aneurysm was then filled with detachable coils. Complete aneurysm occlusion was obtained and there was no evidence to suggest renal infarction on a follow-up contrast CT scan 6 months later. Our preliminary experience suggests that stent-assisted coil embolization of wide-necked renal artery aneurysms is a technically challenging but potentially effective renal-sparing endovascular approach.
The congenital absence of a cervical spine pedicle is a rare clinical condition which is usually picked up as an incidental finding on imaging studies performed on patients complaining of neck pain following trauma. It is important to recognize that the finding is not traumatic in origin as this has implications regarding the treatment. We report a case of congenital absence of a cervical spine pedicle and present a review of the literature.
IntroductionPolyarteritis nodosa can on rare occasions manifest itself as vasculitis of the gallbladder. Patients typically present with right upper quadrant pain and are initially worked up for cholecystitis. The definitive diagnosis is then usually based on surgical and histopathological findings.Case presentationIn this case a 23-year-old Caucasian female presented with a 3 week history of right upper quadrant pain and fevers.ConclusionThe clinical pathway and imaging findings of a rare case of gallbladder vasculitis as a manifestation of polyarteritis nodosa are demonstrated.
Cardiac tumours are relatively rare. Most of them do not cause clinical symptoms so that prior to the introduction of modern methods of investigation they were predominately incidental findings during autopsies or open heart surgery.We present the case of a 63-year-old German man with a past history of malignant melanoma and renal cell carcinoma who presented with a right atrial lipoma and a suspicious lesion in the right lower lobe of the lung. Surgical excision of the cardiac lipoma was performed and a biopsy of the lung mass was done which diagnosed a moderately differentiated adenocarcinoma.
IntroductionTo the best of our knowledge, we present for the first time the bone scintigraphy findings of a patient with Morquio's syndrome.Case presentationA 46-year-old Caucasian man with Morquio's syndrome presented with lower back pain six weeks after a left total hip replacement. A whole body bone scan demonstrated an anthropomorphic skeletal pattern consistent with a mucopolysaccharide storage disease, thereby showing the cause of the patient's pain.ConclusionsTo the best of our knowledge, the bone scintigraphy findings of a case of Morquio's syndrome have never before been published. We present our case report to add to the knowledge we have of this rare disease.
IntroductionAbdominal angina is a descriptive term for abdominal pain that can occur postprandially in patients with occlusive mesenteric vascular disease due to insufficient increase in blood flow.Case presentationIn this case a 60-year-old Caucasian woman with a 2 year history of abdominal angina presented to hospital for elective mesenteric revascularization surgery. Postoperative recovery was complicated by graft occlusion resulting in hepatic ischemia as well as splenic and small bowel infarction.ConclusionThis case highlights the importance of keeping this differential diagnosis in mind when dealing with patients who have a long history of abdominal pain and discusses some of the complications that may occur after surgical treatment.
A persistent sciatic artery is a rare developmental anomaly which may predispose to a range of vascular complications. We report a 60-year-old woman presenting with right lower limb ischemia. Computed tomography angiography revealed an aneurysmal right-sided sciatic artery occluded by thrombus. An aberrant right subclavian artery and anomalous common carotid origins were also incidentally discovered. It is unknown whether an association exists between a persistent sciatic artery and other congenital arterial abnormalities. This is the first case report, so far as we are aware, describing both such arterial anomalies coexisting in a patient.
We present the right to left shunt study findings of a 50-year-old male patient with hepatitis C cirrhosis, who complained of worsening dyspnea on exertion. Follow-up images showed resolution of hepatopulmonary syndrome following methadone withdrawal although there had been no improvement in his liver disease. This was unusual and may have been due to the effect of opiate receptors on nitric oxide signaling in the pulmonary vasculature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
