Nishimoto-Takeuchi-Kudo disease: case report.

Area of Science:

• Neurology
• Vascular Medicine
• Pediatric Neurology

Background:

• Obliterating disorders of large intracranial arteries are rare and can lead to significant neurological deficits.
• The development of collateral circulation, such as a rete mirabile, is a compensatory mechanism in response to arterial occlusion.
• Moyamoya disease, a specific type of progressive cerebrovascular disease, is characterized by stenosis or occlusion of the internal carotid arteries and the development of a collateral network.

Purpose of the Study:

• To report a unique case of an obliterating disorder of the large intracranial arteries in a pediatric patient.
• To describe the formation of an extensive collateral network of the rete mirabile type.
• To compare this case with previously described conditions such as abnormal cerebrovascular networks, occlusion of the circle of Willis, and moyamoya disease.

Main Methods:

• Case report of a 7-year-old boy.
• Clinical presentation and diagnostic imaging findings were analyzed.
• Pathological characteristics of the cerebrovascular network were described.

Main Results:

• The patient presented with an obliterating disorder affecting large intracranial arteries.
• An extensive collateral network, described as a rete mirabile, was observed.
• The findings were analogous to descriptions of abnormal cerebrovascular networks and moyamoya disease.

Conclusions:

• This case highlights a rare presentation of intracranial arterial disease in a child.
• The formation of a rete mirabile-type collateral network is a significant finding in response to arterial occlusion.
• Further research is needed to understand the etiology and optimal management of such conditions.
