Intracranial infantile hemangiomas associated with PHACE syndrome.

BACKGROUND AND PURPOSE: Head and neck infantile hemangiomas are common lesions that are rarely observed in an intracranial location. We report 4 patients with orbital infantile hemangiomas and ipsilateral enhancing intracranial lesions, presumed to be infantile hemangiomas. METHODS: Imaging studies and medical records of 4 infants with orbital hemangiomas and enhancing intracranial lesions were reviewed. The intracranial lesions were evaluated in terms of their location, signal intensity characteristics, enhancement pattern, and degree of involution following treatment. Additional findings associated with PHACE syndrome were also noted and a literature review of intracranial infantile hemangiomas and PHACE syndrome was also performed. RESULTS: The intracranial masses were primarily in or adjacent to the internal auditory canal and demonstrated imaging characteristics and treatment response similar to the ipsilateral orbital lesions. Ipsilateral internal carotid artery hypoplasia, ipsilateral cerebellar hemisphere hypoplasia, and/or other head and neck hemangiomas were present in all patients. CONCLUSION: These cases collectively support the diagnosis of intracranial infantile hemangiomas and suggest a unique radiographic association between PHACE syndrome and intracranial infantile hemangiomas.

Comparison of measured astigmatic retinoscopies from different lid specula.

PURPOSE: We wanted to study the effects of different lid specula on retinoscopy readings in the pediatric population. METHODS: We prospectively enrolled 29 patients from the Eye Clinic at The Children's Hospital of Denver who were being examined under anesthesia and met the inclusion criteria for the study. Any patient with ocular pathology that could affect the pliability of the sclera of both eyes was excluded. Patients with preexisting lid abnormalities or adnexal masses were also excluded. Cycloplegic retinoscopies were performed under anesthesia with the Barraquer wire and the Lancaster solid-blade specula. The amounts and the axes of the astigmatism were tabulated and statistically analyzed with the paired t test. RESULTS: A statistically significant difference occurred in the retinoscopies obtained from the 2 lid specula. The Barraquer lid speculum seemed to induce the least amount of astigmatism (P =.0001). CONCLUSIONS: There was a statistically significant difference in the amount of astigmatism found with each lid speculum. The choice of lid speculum in performing retinoscopies on the pediatric population can influence the final refraction and may have implications for visual outcome.

Hidrotic ectodermal dysplasia with corneal involvement.

BACKGROUND: Persons with ectodermal dysplasias classically have defects in hair, teeth, nails, and sweat glands. Other tissues derived from ectoderm may also be involved. Ocular involvement in ectodermal dysplasias primarily occurs in anhidrotic forms. METHODS: We describe a father and son with hidrotic ectodermal dysplasia. RESULTS: Both patients had recurrent corneal epithelial defects from birth, corneal neovascularization, and strabismus. The father had cataracts with crystalline and amorphous inclusions at an early age. Both patients also had alopecia and skin abnormalities. CONCLUSIONS: A father and son with a previously unreported hidrotic ectodermal dysplasia and unusual corneal findings are described.
