Management of a recurrent stroke due to a carotid web.

Carotid web is a rare intraluminal parietal protrusion in the carotid artery. This vascular anomaly mostly occurs at the bifurcation causing turbulent flow, and is responsible of thrombi formation associated with embolic ischemic events. We report the case of a 35-year-old woman, with no medical history, who presented a recurrent middle cerebral artery (MCA) occlusion within twelve hours caused by a carotid bulb web. Although considered as a rare entity, carotid web is associated with the risk of recurrent strokes in the MCA territory and especially in the absence of the typically recognized risk factors. The key imaging is the CT angiography that shows the web, the cerebral artery occlusion, and the outcome appreciation. Therapeutic strategy associates antithrombotic treatment and operative management with stenting of the carotid web or endarterectomy.

A case report of inflammatory myofibroblastic tumor of cecum mimicking malignant wall thickening.

INTRODUCTION: Inflammatory myofibroblastic tumors (IMT) are an uncommon mesenchymal solid tumor commonly documented in children and young adults (Kim et al., 2012 [1]). Cecum is a rare location of this entity, may simulating a malignant tumor process. PRESENTATION OF CASE: A 71 year old patient was admitted for pain in the right iliac fossa with chronic constipation evolving for two months associated with weight loss. As a diagnosic step, an abdominal computed tomography (CT) scan was performed showing a thickening of the cecal wall. There was no regional or distant metastasis. During a colonoscopy, many biopsies have been returned to a non-specific chronic colitis; as a result, the IMT of the cecum was confirmed pathologically after ilio-coecal resection. DISCUSSION: IMT is difined as a solid mesenchymal tumor basically affects the soft parts as well as the visceral organs. The litterature show that frequent localisations are pulmonary and intra-orbital (Krzysztof Siemion et al., 23 February 2022); therefore, the cecal location is very rare may mimic a malignant tumor (Mauricio Gonzalez-Urquijo et al., January 20, 2020), It is worth recalling that the imaging outcomes are polymorphic and inconclusive; in addition, Surgical excision is the treatment of choice for IMT (Alireza Mirshemirani et al., Dec 2011) and the histopathology is still required for the final diagnosis. CONCLUSION: Radiologic features of IMT present a diagnostic challenge to the radiologist; also, mimic malignancy may lead to unnecessary investigations.
