Summary
Cerebellar haemorrhage in extremely preterm infants is rare, with a low incidence identified via mastoid fontanelle views. Outcomes for isolated cases are generally good, suggesting improved neurodevelopmental results.
Area of Science:
- Neonatal neurology
- Pediatric neuroimaging
- Perinatal medicine
Background:
- Cerebellar haemorrhage (CH) is a serious complication in extremely preterm infants.
- Risk factors and developmental outcomes require further investigation.
Purpose of the Study:
- To determine the incidence of cerebellar haemorrhage in extremely preterm infants.
- To identify associated risk factors.
- To evaluate the neurodevelopmental outcomes of affected infants.
Main Methods:
- Retrospective database review of infants born at 24-27 weeks gestation or with birthweight < 1000g.
- Cranial ultrasound scans, including mastoid fontanelle views.
- Magnetic resonance imaging for verification.
Main Results:
- Five cases of cerebellar haemorrhage identified in 339 neonates (1.2% on ultrasound, 1.5% total).
- Two cases associated with grade III peri-intraventricular haemorrhage showed developmental delay.
- Isolated cerebellar haemorrhage cases demonstrated good neurodevelopmental outcomes.
Conclusions:
- A low incidence of cerebellar haemorrhage was observed, particularly when identified via mastoid fontanelle views.
- Neurodevelopmental outcomes for infants with isolated cerebellar haemorrhage were better than previously reported.

01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
01:17Cerebellum: Anatomical Regions
The cerebellum, also known as the "little brain," is located in the posterior cranial fossa, inferior to the tentorium cerebelli and dorsal to the brainstem. It plays a significant role in motor control, coordination, and proprioception.
Cerebellar Structure
Externally, the cerebellum features a highly convoluted surface with numerous folia (narrow ridges) separated by shallow sulci (grooves). The cerebellum is divided into two hemispheres by a thin median structure known as the vermis. The...

01:19Cerebral Edema l: Introduction
Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
01:29Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
