Lead encephalopathy: symptoms of a cerebellar mass lesion and obstructive hydrocephalus
Insights
Lead poisoning can cause varied neurologic symptoms. This case highlights an unusual presentation of lead encephalopathy in a child with cerebellar edema causing obstructive hydrocephalus.
Area of Science:
- Neurology
- Toxicology
- Pediatrics
Background:
- Lead intoxication presents with diverse neurological manifestations.
- Lead encephalopathy is a severe form of lead poisoning affecting the brain.
Observation:
- A 9-month-old child presented with symptoms mimicking a posterior fossa mass.
- Radiographic imaging revealed obstructive hydrocephalus.
Findings:
- The child's condition was diagnosed as lead poisoning.
- Cerebellar edema was the primary cause of the mass effect and hydrocephalus, an unusual presentation.
Implications:
- This case underscores the importance of considering lead poisoning in pediatric neurological presentations.
- Recognizing unusual presentations of lead encephalopathy is crucial for timely diagnosis and treatment.
Abstract:
The neurologic signs and symptoms of lead intoxication are quite varied. We review a case of lead poisoning in a 9-month-old child who presented clinically and radiographically with a posterior fossa mass effect and obstructive hydrocephalus. The predominance of edema of the cerebellum sufficient to achieve obstruction of the ventricular system represents a particularly unusual presentation of this disease process. Review of the literature for similar cases of lead encephalopathy is included.
