5 yr old baby boy complain of dizziness, headache for 3 days. What is dd and how should i take history
| Diagnosis | Key Distinguishing Features |
|---|---|
| CNS tumor (posterior fossa / cerebellar) | ~45–60% of childhood brain tumors arise in brainstem/cerebellum; progressive ataxia, morning vomiting, papilledema, nocturnal awakening |
| Intracranial hemorrhage / SAH | Thunderclap onset, altered consciousness, meningismus |
| Meningitis / Encephalitis | Fever, neck stiffness, photophobia, altered GCS |
| Brain abscess | Fever, immunocompromised state, focal deficits |
| Pediatric stroke | Children present atypically — headache, seizure, altered consciousness; look for focal neuro deficits |
| Intracranial hypertension | Headache worse lying down/morning, vomiting, papilledema |
| Hypertensive emergency | Check BP — renal disease, renovascular, coarctation |
| Diagnosis | Key Features |
|---|---|
| Benign Paroxysmal Vertigo of Childhood (BPVC) | Most common in ages 4–8 years; sudden episodic vertigo seconds–minutes; migraine precursor; family history of migraine/motion sickness |
| Migraine with or without aura | Throbbing, unilateral or bilateral, photophobia, nausea/vomiting; positive family history |
| Vestibular neuritis / labyrinthitis | Post-viral, sustained vertigo, nystagmus; associated URTI |
| Otitis media with effusion | Mild imbalance, ear fullness, recent URTI/fever |
| Benign Paroxysmal Positional Vertigo (BPPV) | Less common in children without head trauma; triggered by position change |
| Febrile illness | Rule out viral illness as cause of headache + dizziness |
| Diagnosis | Key Features |
|---|---|
| Acute mountain sickness | Change in altitude/environment |
| Anemia / hypoglycemia | Pallor, dietary history, fatigue |
| Carbon monoxide poisoning | Multiple family members affected, diffuse headache |
| Psychogenic / anxiety | School refusal, social stressors; diagnosis of exclusion |
| Post-traumatic | History of head injury within 7 days |
| Medication/toxin ingestion | Accidental — toxicology screen highest yield in pediatric acute ataxia |
⚠️ Any of these = consider urgent CT/MRI brain:
