Introduction An infected popliteal pseudoaneurysm has never been described in the pediatric population. Physicians need to be aware of its presentation and management, in order to diagnose and treat this medical condition adequately. Methods We describe the case of a 14-year-old boy who developed myositis and cellulitis centered at the popliteal fossa after playing basketball. A treatment of intravenous cefazolin was started. 5 days later, he experienced a knee pain flare-up, which turned out to be a popliteal pyomyositis with a pseudoaneurysm of the popliteal artery. A saphenous vein graft bypass of the popliteal artery and an excision of the popliteal pseudoaneurysm were performed. Intravenous cefazolin was continued for 6 weeks and prophylactic acetylsalicylic acid for 6 months. Results and conclusion This case highlighted the importance of repeating radiologic investigations if a patient suffering from soft tissue infection has persistent pain after several days of appropriate antibiotics. A popliteal pseudoaneurysm can be diagnosed with ultrasound imaging and treated with a popliteal-popliteal bypass. Our patient needed a catheter-guided dilation of the anastomosis at the vein graft 6 months post-surgery, and then evolved favorably and went back to playing basketball 6 months post-dilation.

OBJECTIVE In nonambulatory children with predominantly spastic cerebral palsy (CP), the authors compared care needs, symptom burden, and complications after surgical treatment with either intrathecal baclofen (ITB) pump insertion or selective dorsal rhizotomy (SDR). The patients were treated at two Canadian centers with variability in practice pertaining to these surgical options. METHODS The authors performed a retrospective analysis of nonambulatory children with predominantly spastic quadriplegic or diplegic CP who underwent treatment with ITB or SDR. These two strategies were retrospectively assessed by comparing patient data from the two treatment groups for demographic characteristics, outcomes, and complications. A partial least-squares analysis was performed to identify patient phenotypes associated with outcomes. RESULTS Thirty patients who underwent ITB and 30 patients who underwent SDR were included for analysis. Patients in the ITB group were older and had lower baseline functional status, with greater burdens of spasticity, dystonia, pain, deformity, bladder dysfunction, and epilepsy than patients in the SDR group. In addition, children who underwent SDR had lower Gross Motor Function Classification System (GMFCS) levels and were less likely to experience complications than those who underwent ITB. However, children treated with SDR had fewer improvements in pain than children treated with ITB. A single significant latent variable explaining 88% of the variance in the data was identified. CONCLUSIONS Considerable baseline differences exist within this pediatric CP patient population. Factors specific to individual children must be taken into account when determining whether ITB or SDR is the appropriate treatment.
