Summary
Sinus pericranii (SP), a rare vascular condition, can present with hydrocephalus. This case highlights a sudden scalp mass indicating increased intracranial pressure and hydrocephalus in a young patient.
Area of Science:
- Vascular Surgery
- Neurology
- Pediatric Neurosurgery
Background:
- Sinus pericranii (SP) involves abnormal intracranial and extracranial venous system communication.
- It is a rare vascular malformation with varied etiologies and associations.
- Understanding SP is crucial for diagnosing associated neurological conditions.
Observation:
- A 13-year-old girl presented with acute onset of a scalp mass, proptosis, vision loss, nausea, and headaches.
- Brain imaging revealed communicating hydrocephalus and subcutaneous vascular collaterals.
- The sudden appearance of the scalp mass preceded the neurological symptoms.
Findings:
- This report details the first case of idiopathic sinus pericranii associated with hydrocephalus.
- The patient's hydrocephalus resolved after ventriculoperitoneal shunt insertion, with disappearance of extracranial veins.
- The sudden change in SP size was indicative of increased intracranial pressure and hydrocephalus.
Implications:
- Sudden changes in sinus pericranii size may signal the development of hydrocephalus.
- This case expands the understanding of SP presentations and associations.
- Early recognition and management are vital for patients with sinus pericranii and hydrocephalus.
