Degos disease: A radiological-pathological correlation of the neuroradiological aspects of the disease.

ABSTRACT

Malignant atrophic papulosis (Degos disease) is an unusual thrombotic microangiopathy of uncertain etiology. The disease characteristically involves the skin and internal organs, with nervous system involvement more common in children. We present a case with diverse neurological manifestations including cranial nerve palsies, gait instability, and urinary incontinence. The patient also developed white papular lesions on her lower extremities and back. Magnetic resonance imaging (MRI) demonstrated progressive intracranial and spinal abnormalities. Despite treatment with numerous biologic agents, the patient had persistent clinical deterioration and expired one month after admission. We highlight the extensive neurologic manifestations of Degos disease correlated with neuroradiological imaging and pathological features. Nervous system involvement in Degos disease requires careful neurologic and dermatologic exam with central nervous system (CNS) magnetic resonance imaging to distinguish it from non-organic etiologies of similar symptoms.
