Sign and symptoms of Brain tumors in children
Children with brain tumors frequently have symptoms and signs that strongly suggest the appropriate diagnosis.
The clinical triad of symptoms associated with increased ICT -4 headache, vomiting, blurred vision / diplopia, is the hallmark of brain tumors in childhood.
These symptoms occur more frequently with mid-line posterior fossa (infratentorial) tumors owing to the propensity of lesions close to the ventricular CSF flow system.
Symptoms of the brain tumors vary depending upon which part of the brain the tumor is found :
Brain tumor in cerebrum (supratentorial)
Seizures o Hemiperes is or Hemiplegia o Drowsiness / confusion
Visual changes o T ICT (less common) o Personality changes
Brain tumor in brain stem
Seizures o Diplopia o Respiratory changes o T ICT (Rare)
Endocrine problem (DM) o Headache o Cranial N. palsy
Brain tumor in cerebellum
T ECT (most common) o Headache o Uncoordinated movement
Vomiting o Ataxia
Symptoms due to raised ICT --> These are mainly caused by midline posterior fossa tumor --> Medulloblastoma.
Headache o Nausea o Drowsiness
Vomiting (usually in the morning) o Personality changes o Papilledema
Diplopia / blurred vision o Irritability
Note - Brain-stem tumors are also posterior fossa tumors, but they do not present with increased ICT.
