| Abstract|| |
A three-months boy presented with recurrent seizures. On examination, he was fair, had dilated scalp veins, sparse hypopigmented hair, and was hypotonic. X-ray of the skull showed wormian bones. The child was diagnosed with Menkes disease. The manuscript aims to emphasize dilated scalp veins in diagnosis of Menkes disease.

A 3-month-old boy presented with lethargy, refusal to feed, and left focal tonic seizures involving the face and upper and lower limbs lasting about a minute for the last 4 days. On examination, he had a fair complexion, sparse hypopigmented hair, brachycephaly, and visibly dilated superficial veins over the scalp [Figure 1]. The child had hypotonia, normal deep tendon reflexes, and normal sensory examination. A suspicion of Menkes disease arose because of the fair complexion, sparse and light-colored hair, and seizures. The hair microscopy did not reveal pili torti or trichorrhexis nodosa. An X-ray of the skull showed prominent markings of dilated skull veins on bones [Figure 1]. The serum copper and ceruloplasmin were 17.3 µg/dL (range 70–140 µg/dL) and 3.9mg/dL (range 20–35mg/dL) respectively. A magnetic resonance imaging of the brain revealed tortuosity of the intracranial vessels. On next-generation sequencing, a contiguous region corresponding to exons 8–12 and partial region of exon 13 of the ATP7A gene (ENST00000341514) was not covered in the sequence data of this sample. This region is usually well covered, and hence could likely be due to hemizygous deletion of the region in the gene. These suggest that the deletion is likely pathogenic. The child succumbed to refractory seizures at home after 1 month. The parents were provided genetic and prenatal counseling.

Menkes disease is an X-linked recessive disease of copper metabolism. Deficiency of copper-containing enzymes leads to abnormal collagen formation, leading to alterations of skin, hair, bones, and blood vessels. Tortuosity of the intracranial arteries and phlebectasia of venous channels have been reported., Dilated scalp veins may represent an extension of the same pathophysiological process and serve as an important examination finding for suspecting Menkes disease in an infant. Other skeletal changes include diaphyseal and metaphyseal fractures and metaphyseal spurs. The case highlights that a simple skull radiograph might suggest an underlying abnormality in intracranial vessels, and can clinically narrow down the diagnosis of Menkes disease.
