Background and Objective: Basilar invagination and atlas assimilation are significant craniovertebral anomalies that typically present with symptoms in the 3rd and 4th decades of life. These anomalies are concerning because they are in close proximity to the vital structures surrounding the foramen magnum, including the brainstem and spinal cord. However, these conditions are rarely reported in younger populations, making early diagnosis and intervention in such cases particularly difficult.
Case Report: This report presents the case of a term neonate born to a primigravida mother by emergency lower segment cesarean section. The infant, who was initially discharged after resolution of respiratory distress, was readmitted at two weeks of age with generalized weakness. The initial management approach focused on treating the condition as late-onset sepsis and meningitis. However, after ruling out other causes for the generalized hypotonia, subsequent computed tomography (CT) of the head and spine revealed compressive myelopathy secondary to basilar invagination and atlas assimilation, as well as gross hydrocephalus. These findings emphasize the presence of a craniovertebral anomaly at an exceptionally early stage of life..
Conclusions: This study revealed the positive effect of the interventions on most of FMS variables, and the sports game group performing better. Due to the modality of the physical activity interventions, the integration of these two types of interventions may show a better effect.
