Massive adrenal vein aneurysm mimicking an adrenal tumor in a patient with hemophilia A: a case report and review of the literature

Acute digit ischemia due to a ruptured digital collateral artery aneurysm in a patient of hemophilia: A case report

Introduction

Digital artery aneurysms are a rare event but cases have been reported in the literature. The hemostasis disorders make these aneurysms particularly dangerous with potentially irreversible hand complications: Compression of adjacent vascular and nervous structures, embolization of associated thrombi, finger ischemia, and necrosis.

Case Report

We reported a case of digital ischemia due to a ruptured aneurysm of a digital collateral artery, leading to the diagnosis of congenital hemophilia A. Hematoma evacuation allowed finger revascularization. Complete symptom resolution required ligature excision associated with Factor VIII supplementation.

Conclusion

Aneurysms of the digital collateral arteries are a rare event. In the case of a hemophilic patient, surgical management is necessary, and medical treatment alone is not sufficient. The consequences of a ruptured aneurysm in this type of patient can be serious. A close monitoring is required to ensure the absence of early recurrence.

Internal carotid artery dissection in a patient with hemophilia A: a case report and literature review

Spontaneous cervical artery dissection (sCeAD) is the most common cause of ischemic stroke at a young age, but its pathogenetic mechanism and risk factors are not fully elucidated. It is reasonable to think that bleeding propensity, vascular risk factors such as hypertension and head or neck trauma, and constitutional weakness of the arterial wall together play a role in the pathogenesis of sCeAD. Hemophilia A is known to be an X-linked condition that leads to spontaneous bleeding in various tissues and organs. To date, a few cases of acute arterial dissection in patients with hemophilia have been reported, but the relationship between these two diseases has not been studied so far. In addition, there are no guidelines indicating the best antithrombotic treatment option in these patients. We report the case of a man with hemophilia A who developed sCeAD and transient oculo-pyramidal syndrome and was treated with acetylsalicylic acid. We also review previous published cases of arterial dissection in patients with hemophilia, discussing the potential pathogenetic mechanism underlying this rare association and potential antithrombotic therapeutic options.

Mimics, pitfalls, and misdiagnoses of adrenal masses on CT and MRI

Due to the widespread use of imaging, incidental adrenal masses are commonly encountered. A number of pitfalls can result in misdiagnosis of these lesions, including inappropriate choice of imaging technique, presence of pseudolesions, and overlap of imaging features of different adrenal lesions. This article explores the potential pitfalls in imaging of the adrenal glands, on computed tomography and magnetic resonance imaging, that can lead to misinterpretation. Clues to correct diagnoses are provided to evade potential misinterpretation.
