✓ Fibrodysplasia ossificans progressiva (FOP) is a rare, autosomal dominant disorder characterized by congenital malformation of the great toes and episodes of soft tissue swelling that lead to progressive heterotopic ossification. The genetic cause of FOP was recently discovered to be a recurrent missense activating mutation in the activin A type I receptor, a bone morphogenetic protein type I receptor in all classically affected individuals worldwide. The authors present a child with the classic features of previously undiagnosed FOP who developed a paraspinal soft-tissue mass after a lumbar puncture for a fever workup. Excision of the mass resulted in a massive inflammatory response leading to progression of heterotopic ossification. Awareness of the classic clinical features of FOP prior to the appearance of heterotopic ossification can prompt early clinical diagnosis and confirmation through genetic testing, thus avoiding interventions that lead to irreversible iatrogenic harm.

Schizencephaly is a rare congenital cortical brain malformation defined by unilateral or bilateral clefts of the cerebral hemispheres. These malformations are often associated with medically intractable epilepsy. Surgical solutions include lesionectomy, lobectomy, or hemispherectomy. The authors describe the case of an anatomic hemispherectomy for medically intractable epilepsy in an 8-year-old boy with a large schizencephalic cleft. Seven years prior to his epilepsy surgery, the patient underwent placement of a ventriculoperitoneal shunt for communicating hydrocephalus that resulted in severe left-to-right shift. Subsequently, medically refractory epilepsy developed and the patient underwent an anatomic hemispherectomy for seizure control. The preoperative brain shift remained after the surgery, although the patient tolerated the procedure well and was seizure free postoperatively. Anatomic hemispherectomy is a viable option for treating medically intractable epilepsy in a schizencephalic pediatric patient—even one with considerable brain shift.
