Crohns disease with central nervous system vasculitis causing subarachnoid hemorrhage due to aneurysm and cerebral ischemic stroke

Cerebral vasculitis secondary to Crohn′s disease (CD) seems to be a very rare phenomenon. We report a 39-year-old male who presented with headache, vomiting, and left-sided weakness in the known case of CD. Cross-sectional imaging (computed tomography and magnetic resonance imaging,) showed right gangliocapsular acute infarct with supraclinoid cistern subarachnoid hemorrhage (SAH). Cerebral digital substraction angiography (DSA) showed dilatation and narrowing of right distal internal carotid artery (ICA). Left ICA was chronically occluded. His inflammatory markers were significantly raised. Imaging features are suggestive of cerebral vasculitis. Arterial and venous infarcts due to thrombosis are known in CD. Our case presented with acute subarachnoid hemorrhage in supraclinoid cistern due to rupture of tiny aneurysm of perforator arteries causing SAH and infarction in right basal ganglia. Patient was treated conservatively with immunosuppression along with medical management of SAH

Cavernous sinus melanoma: A rare tumor

Primay melanoma of the cavernous sinus is very rare with only few cases reported in the literature. We present the cross-sectional imaging findings of this rare tumor. The differential diagnosis for cavernous sinus mass lesion is wide as it contains vital neurovascular structures that may be affected by vascular, neoplastic, infective, and infiltrative lesions arising in the cavernous sinus proper or via extension from adjacent intra and/or extracranial regions. Radiologic imaging can narrow the differential diagnosis, however, imaging cannot definitely reach single diagnosis if they present in atypical form with hemorrage and cystic degeneration. This case report illustrates that primary cavernous sinus melanoma may present as a atypical tumor with diagnostic dilemma

Haemorrhagic shock due to spontaneous splenic haemorrhage complicating antiplatelet therapy: endovascular management

Spontaneous splenic haemorrahge and rupture is a rare but life-threatening condition requiring urgent diagnosis and treatment. Splenic haemorrhage and rupture precipitated by thrombolytic or antiocoagulant therapy has been reported frequently in the literature, but only two cases due to ticlopidine and one case due to salicyclate have been reported. We report the case of a 54-year-old man with haemorrhagic shock due to spontaneous splenic haemorrhage and rupture following dual antiplatelet (aspirin and clopidogrel) therapy. He was successfully treated with selective angioembolization of the bleeding branch of the splenic artery

Endovascular management of bowel ischemia secondary to portal and mesenteric vein thrombosis

Portal and mesenteric venous thrombosis (PMVT) is an uncommon disease, but it is a clinically important case of acute mesenteric ischemia. Its diagnosis is often delayed because of nonspecific abdominal symptoms. The treatment of PMVT involves anticoagulation therapy, alone or in combination with surgery. The addition of thrombolytic therapy to the treatment of PVMT may enhance the clearance of thrombus and hasten the clinical improvement. We herein present a case of bowel ischemia due to PVMT that was successfully treated with catheter-directed infusion of urokinase through the superior mesenteric artery and systemic anticoagulation in a patient with ascites and high blood international normalized ratio. We believe that this case demonstrates that slow and steady treatment with transarterial thrombolysis over 13 days can achieve the desired Results compared with more aggressive transhepatic or transjugular thrombectomy or surgical thrombectomy, especially in high-risk patients with ascites and high international normalized ratio

Radiofrequency ablation of osteoid osteoma in common and technically challenging locations in pediatric population

Context: Percutaneous radiofrequency ablation (RFA) of osteoid osteoma has a high technical and clinical success rate. However, there is limited data on its use in the pediatric population, especially in technically challenging locations. Objective: To assess the safety and efficacy of computed tomography (CT)-guided percutaneous RFA of osteoid osteoma in pediatric population. Patients and Methods: From June 2009 to May 2014, 30 patients with osteoid osteoma were treated with CT-guided RFA in common (25 cases) and technically challenging (five cases: four near articular surface and one in sacrum) locations. Therapy was performed under general anesthesia with a three-array expandable RF probe for 6 min at 90°C and power of 60–100 W. The patients were discharged next day under instruction. The treatment success was evaluated in terms of pain relief before and after (1 day, 1 month, and 6 months) treatment. Results: Technical success was achieved in all patients (100%). Primary clinical success was 96.66% (29 of total 30 patients), despite the pediatric population and atypical location. One patient had persistent pain after 1 month and was treated successfully with a second procedure (secondary success rate was 100%). One patient had immediate complication of weakness of right hand and fingers extension. No delayed complications were observed. Conclusions: CT-guided RFA is relatively safe and highly effective for treatment of osteoid osteoma in pediatric population, even in technically difficult locations
