Skull Pathologies Flashcards
What are the clinical indications for imaging the skull?
(5)
Trauma
Infection
Tumours
Congenital and developmental conditions
Dental pathologies
What are the imaging modalities for the skull?
(3)
CT
MRI
X-rays
How can the fractures of the cranium be divided?
(4)
Anatomically
Associated with overlying wound
Degree of displacement
Number of fracture lines/fragments
How can fractures of the cranium be divided (anatomically)?
(2)
Drastic
Basilar
What does the cranium being fractured anatomically diastatic mean?
Separation of cranial sutures
What does the cranium being fractured anatomically basilar mean?
Base of the cranium is fractured
What are the 2 ways that the cranium can be fractured associating with overlying wound?
Open (compound)
Closed
What are the 2 ways that the cranium can be fractured with a degree of displacement?
Undisplaced
Depressed (5-10mm)
What are the 2 ways that the cranium can be fractured by the number of fracture lines/fragments?
Linear
Comminuted
What are the types of fractures that occur on then cranium?
How would we describe this CT scan of the skull?
(Fall from the 2nd storey)
Linear occipital fracture
How would we describe this skull fracture?
(Assault)
Linear fracture of the left parietal bone
How would we describe this skull fracture?
(Dive into a shallow pool)
Linear parietal fracture
How would we describe this skull fracture?
(Crash in a traffic accident)
Linear frontotemporal fracture
How would we describe this skull fracture?
(Motorbike accident)
Bilateral occipital condyle fractures
How would we describe this skull fracture
(Teenager in RTA with flipped car)
Comminuted depressed right frontal bone skull fracture
What is craniosynostosis?
The premature closure of the cranial sutures. The skull shape then undergoes characteristic changes depending on which suture close early
