Spontaneous Isolated Inferior Mesenteric Artery Dissection With Chronic Mesenteric Ischemia: Case Report and Endovascular Management

We report the clinical details, imaging findings, and management for a 39-year-old female presenting with recurrent episodes of pain in abdomen due to systemic lupus erythematous vasculitis associated with spontaneous isolated inferior mesenteric dissection. Spontaneous mesenteric artery dissection is an uncommon cause of mesenteric ischemia. Symptomatic spontaneous isolated inferior mesenteric artery (IMA) dissection is a rare condition, and its association with systemic lupus erythematosus is not previously described in the English literature. The optimal treatment options are debatable and include medical management, surgical reconstruction, and endovascular therapy. We wish to highlight spontaneous isolated IMA dissection as a rare etiology for chronic mesenteric ischemia and its management by endovascular methods. </jats:p

Endovascular glue embolization for control of massive hemoptysis caused by peripheral pulmonary artery pseudoaneurysms: Report of 7 cases

Purpose: Pulmonary artery pseudoaneurysms are a rare cause of massive hemoptysis and need to be considered as a differential with prompt recognition preventing mortality from life-threatening hemorrhage. We report the clinical details and imaging findings for a series of patients presenting with massive haemoptysis due to peripheral pulmonary artery pseudoaneurysm, managed by endovascular glue embolization. Methods: Hospital based retrospective study wherein records and image database of patients presenting with massive hemoptysis between January 2014 and March 2016 were studied. The immediate technical success, reintervention rate, and recurrence of massive hemoptysis were recorded. Results: Among patients with massive hemoptysis who underwent endovascular management in our department, seven patients fulfilled the inclusion criteria. The mean age was 54.3 years; mean lesion diameter was 10.8 mm (range 6–14 mm); underlying pathology being infective (tuberculosis) in all cases (n = 7). All lesions were treated with endovascular glue embolization. The technical success was 100%. Mean follow-up was 11.7 months. There was no case of recurrence of massive hemoptysis. There were no major complications with a single case of minor complication (in the form of chest pain and discomfort) which resolved with medical management. Conclusion: The endovascular approach using glue (N-butyl cyanoacrylate) is a minimally invasive and technically feasible, effective technique for emergent management of pulmonary artery pseudoaneurysms presenting as massive hemoptysis

Nondecussating retinal-fugal fiber syndrome: Clinical and neuroimaging clues to diagnosis

We report the clinical details and imaging findings for a case of nondecussating retinal-fugal fiber syndrome or isolated achiasma in a 4-year-old female child. Findings included the isolated absence of optic chiasm with unremarkable rest of the optic pathway and midline structures in a child presenting clinically with see-saw nystagmus. Clinically congenital see-saw nystagmus, "mirror reversal" of visual field representation and interocular ipsilateral asymmetry on monocular visual evoked potential point toward achiasma and warrant further evaluation with magnetic resonance imaging (MRI). Isolated achiasma is a rare condition that may remain undiagnosed unless MRI is done
