“…The indications for the initial evaluation were variable. These included vascular abnormalities (such as moyamoya disease, 15,28,31 dural arteriovenous fistula, 14 cavernous malformation with developmental venous anomaly, 4 AVMs 2 in other location, and intraparenchymal hemorrhage 25 ) and nonvascular conditions such as a brain tumor, 24 neuronal migration abnormality, 33 Bell's palsy, 23 head trauma, 16 and demyelinating lesions. 7 Repeat imaging leading to the diagnosis of the de novo AVM was performed after a prolonged interval, ranging from 2 to 17 years, for the purpose of following up the original lesion or due to the acute development of symptoms (which were related to AVM rupture in 3 cases).…”

A long-held dogma in neurosurgery is that parenchymal arteriovenous malformations (AVMs) are congenital. However, there is no strong evidence supporting this theory. An increasing number of documented cases of de novo formation of parenchymal AVMs cast doubt on their congenital nature and suggest that indeed the majority of these lesions may form after birth. Further evidence suggesting the postnatal development of parenchymal AVMs comes from the exceedingly rare diagnosis of these lesions in utero despite the widespread availability of high-resolution imaging modalities such as ultrasound and fetal MRI. The exact mechanism of AVM formation has yet to be elucidated, but most likely involves genetic susceptibility and environmental triggering factors. In this review, the authors report 2 cases of de novo AVM formation and analyze the evidence suggesting that they represent an acquired condition.

“…4 Although the rare association of moyamoya disease with an AVM has been documented in detail, the development of de novo AVMs in patients with moyamoya disease is extremely rare; it has been reported in only 2 pediatric cases. 3,5 Here, we describe a 10-yearold girl with ischemic-onset moyamoya disease who underwent successful bilateral revascularization surgeries and developed acquired AVM in the occipital lobe during the 4-year follow-up period.…”

The development of a de novo arteriovenous malformation (AVM) in patients with moyamoya disease is extremely rare. A 14-year-old girl developed an AVM in the right occipital lobe during the 4-year postoperative period following successful bilateral revascularization surgeries. She suffered a transient ischemic attack with hemodynamic compromise of the bilateral hemispheres at the age of 10 years. Results of an initial examination by 1.5-T MRI and MR angiography satisfied the diagnostic criteria of moyamoya disease but failed to detect any vascular malformation. Bilateral direct and indirect revascularization surgeries in the anterior circulation relieved her symptoms, and she underwent MRI and MR angiography follow-up every year after surgery. Serial T2-weighted MRI revealed the gradual appearance of flow voids in the right occipital lobe during the follow-up period. Magnetic resonance angiography ultimately indicated the development of an AVM 4 years after these surgeries when catheter angiography confirmed the diagnosis of an AVM in the right occipital lobe. The AVM remained asymptomatic, and the patient remained free of cerebrovascular events during the time she was observed by the authors. Acquired AVM in moyamoya disease is extremely rare, with only 3 pediatric cases including the present case being reported in the literature. The development of a de novo AVM in a postoperative patient with moyamoya disease appears to be unique, and this case may provide insight into the dynamic pathology of AVMs.

“…The case presented herein adds to only 15 reported cases of de novo AVM [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] that challenge the concept of congenital aetiology. Furthermore, this case is only the eighth case described in a child without underlying cerebrovascular disease such as moya-moya disease, or a history of previous vascular malformation ( Table 1).…”

Intracerebral arteriovenous malformations (AVM) have traditionally been considered congenital lesions. This model of pathogenesis has recently been challenged following a small number of reports describing de novo presentation of AVM in patients with pre-existing cerebrovascular disease.However, we present the case of a 4 year-old boy presenting with headache, with no history of cerebrovascular disease, whose imaging demonstrated a SpetzlerMartin grade 3 AVM in the left superior temporal gyrus. The patient was previously investigated for seizures as a neonate and at this time magnetic resonance imaging identified no underlying abnormality.We present a case of de novo AVM in a child without pre-existing cerebrovascular disease, adding to a limited number of pre-existing reports and discuss it in context of recent advances in the understanding of AVM pathogenesis.
