PHACE syndrome (P: posterior fossa malformations, H: haemangioma, A: arterial anomalies, C: coarctation of the aorta and cardiac defects, E: eye abnormalities, S: sternal defects) is one of the neurocutaneous disorders. It describes a constellation of abnormalities that can occur in association with segmental craniofacial infantile haemangioma, which is the hallmark of this syndrome. Intracranial anomalies are the most common extracutaneous feature of PHACE syndrome. Typical intracranial malformations include posterior fossa malformations like Dandy-Walker complex and cerebellar hemispheric hypoplasia ipsilateral to the hemangioma, arterial anomalies like agenesis, aneurysms, arterial kinking or coiling, Moyamoya-like collateralization and persistent embryonic arteries. Less frequent findings include cortical dysplasia and cortical migration anomalies, dysplasia of the corpus callosum, intracranial capillary hemangiomas and arachnoid cysts. We present 3 cases which we think significantly contribute to the growing recognition of relatively unique intracranial associations that are likely important for the diagnosis of PHACE syndrome.

Post-traumatic osseous cystic lesions are a rare complication in children. An etiology of intramedullary fat seepage thorough the damaged bone cortex and its entrapment within the subperiosteum has been proposed. These lesions run a benign course and usually resolve spontaneously. The presence of fatty marrow gives it a distinct appearance which aids in its diagnosis and differentiation from other bone lesions. This case demonstrates a fat-fluid level within the subperiosteal cystic lesion in MRI and this is a typical feature of post-traumatic cystic lesion in a child. Recognition of this feature allows for a confident diagnosis, cutting down on unnecessary, potentially invasive investigations. Read More
