Objective: To report a case of PHACE syndrome-Posterior fossa brain abnormalities, Hemangioma (usually facial), Arterial anomalies, Coarctation of the aorta along with cardiac defects, and Eye abnormalities-in a 16-year-old female patient with a port-wine stain of the right periorbital area present since birth in conjunction with hypoplasia of the contralateral internal carotid artery.
Methods: Thyroid-stimulating hormone, free thyroxine, and growth hormone (GH) levels were measured, and insulin-induced hypoglycemia and arginine infusion tests were done. Radiologic investigations included sagittal enhanced T1-weighted magnetic resonance imaging of the brain and the pituitary gland as well as computed tomography and magnetic resonance angiography of the head and neck.
Results: The patient had a normal karyotype. Her height and weight were below the 5th percentile for her chronologic age, and she had amenorrhea. Laboratory investigations revealed both thyroid and GH deficiencies and confirmed the diagnosis of hypogonadotropic hypogonadism. The imaging studies showed a right intraorbital hemangioma as well as an enhancing mass in the right internal auditory canal at the cerebellopontine angle, consistent with a posterior fossa hemangioma. Initiation of both thyroid and GH replacement therapy improved her growth rate and yielded a good clinical outcome.
Conclusion: In patients with facial or neck hemangiomas, PHACE syndrome should be suspected, and brain imaging and cardiac, ophthalmologic, and endocrinologic evaluations are recommended to screen for other potential PHACE abnormalities.

A 13-month-old boy presented to the pediatric ophthalmology clinic at BC Children's Hospital for strabismus assessment. On examination he had a right facial hemangioma, left ptosis, and left exotropia and hypotropia. Magnetic resonance imaging and magnetic resonance angiography of his head demonstrated posterior cerebral artery tortuosity producing mild mass effect on the left oculomotor nerve.

Article Synopsis
- PHACE syndrome is a complex prenatal condition that can have significant health implications, often identified through specific signs observed in prenatal imaging.
- The 'tilted telephone receiver' sign suggests a strong link to PHACE, but recent cases show it can also appear in less severe forms, prompting discussions about expanding how we recognize this syndrome.
- A particular case with mild symptoms resembling PHACE did not actually result in the condition after birth, indicating that expanded criteria for diagnosis could lead to incorrect negative predictions for affected pregnancies.

Article Synopsis
- PHACE syndrome is a neurocutaneous disorder characterized by brain abnormalities, facial hemangiomas, and various arterial and cardiac issues.
- While visible hemangiomas are the most prominent symptom, serious complications like aortic anomalies and strokes can arise, making early identification crucial.
- The article reviews important clinical features, diagnostic approaches, and management strategies, highlighting the significance of this condition for pediatric neurologists.

Article Synopsis
- Infantile hemangiomas (IHs) are common vascular tumors that typically develop during the first few weeks of an infant's life, but the precursor lesions can be mistaken for other conditions.
- A study reviewed nine cases of neonates with initial lesions observed on their first day, comparing these early signs with classic IHs and documenting treatment details.
- Better identifying precursor lesions can enhance diagnosis, minimize unnecessary procedures, and lead to quicker evaluations for related syndromes in more severe cases.
