Intraventricular hemorrhage of prematurity (IVH) is a diagnosis that has become more frequent in recent years. Advances in medical care have led to survival of increasingly premature infants, as well as infants with more complex medical conditions. Treatment with a ventricular access device (VAD) was reported almost 3 decades ago; however, it is unclear how effective this treatment is in the current population of premature infants. At our institution (from 2004 to present), we treat posthemorrhagic hydrocephalus (PHH) with a VAD. In order to look at safety and efficacy, we retrospectively combed the medical records of premature children, admitted to Lucile Packard Children's Hospital from January 2005 to December 2009, and identified 310 premature children with IVH. Of these, 28 children required treatment for PHH with a VAD. There were no infections associated with placement of these devices and a very low rate of other complications, such as need for repositioning (7.41%) or replacement (3.75%). Our data show that treatment with a VAD is very safe, with few complications and can be used to treat PHH in this very complex infant population. Copyright © 2012 S.

Posterior fossa syndrome (PFS), also known as cerebellar affective syndrome, is characterized by emotional lability and decreased speech production following injury or surgery to the cerebellum. Rarely, oculomotor dysfunction has been described in association with PFS. Here, we report a case of complete ocular paresis associated with PFS in an 11-year-old male following medulloblastoma resection. Copyright © 2012 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

Background/Aims: To review the pathological distribution of pediatric primary skull tumors, and to determine the diagnostic value of lesion location, patient age and lesion size. Methods: A retrospective chart review identified 51 consecutive pediatric patients with 54 primary skull tumors, treated between 2005 and 2010. Results: The most common diagnoses were dermoid cysts (n = 34) and fibrous dysplasia (n = 5). While dermoid tumors could reside anywhere (sensitivity = 0.41), a midline lesion had a specificity of 0.9 and a positive predictive value of 0.88. All of the fibrous dysplasia lesions were laterally placed, with a negative predictive value (NPV) of 1. Patient age < or >5 years had a high sensitivity and NPV for dermoid cysts and fibrous dysplasia, respectively. Size appeared to be sensitive (0.91, 0.8), but not specific (0.6, 0.78), with good NPV (0.8, 0.97) when considering dermoid cysts (≤2 cm) or fibrous dysplasia (>2 cm), respectively.Conclusion:Dermoid cysts followed by fibrous dysplasia are the most common primary skull tumors. Lesion location, patient age and lesion size give important clues as to the diagnosis. For the majority of cases, a clinical diagnosis based on CT is sufficient for presurgical evaluation.
