Summary
Pseudotumor cerebri diagnosis can be challenging. This case highlights sutural diastasis on radiography as a potential diagnostic clue in obese patients, aiding prompt treatment to prevent vision loss.
Area of Science:
- Neurology
- Radiology
- Ophthalmology
Background:
- Pseudotumor cerebri (idiopathic intracranial hypertension) diagnosis relies on papilledema, elevated intracranial pressure with normal cerebrospinal fluid, and normal neuroimaging.
- Diagnostic challenges exist, particularly in atypical presentations.
- Obesity is a known risk factor for pseudotumor cerebri.
Observation:
- A 19-year-old morbidly obese female presented with pseudotumor cerebri.
- Direct radiography revealed associated sutural diastasis of the cranium.
- This finding was unexpected given the typical diagnostic criteria.
Findings:
- The patient underwent ventriculo-peritoneal shunt surgery for pseudotumor cerebri.
- Post-operatively, direct radiography demonstrated closure of cranial sutures with perisutural sclerosis.
- This suggests a dynamic relationship between intracranial pressure and cranial suture integrity.
Implications:
- Careful examination of direct radiographs may be crucial for diagnosing pseudotumor cerebri, especially in cases with unusual findings.
- Sutural diastasis on radiography could be an indicator of elevated intracranial pressure in specific patient populations.
- Early recognition and intervention are vital to prevent irreversible visual impairment associated with pseudotumor cerebri.

01:22Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

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...
01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:26Cerebrum: Anatomical Overview I
The main and largest component of the human brain is the cerebrum. The cerebrum consists of two main parts: the cerebral cortex, an outer layer with wrinkles or folds known as gyri and shallow grooves called sulci, and a deeper region beneath it. The cerebrum divides into two distinct hemispheres and contains five different lobes: the frontal, parietal, temporal, occipital, and insula. The central sulcus separates the frontal and parietal lobes and two functionally important gyri — the...
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...
