Radiolucent Lesions II Flashcards
sarcomas in general can do what to bone
enlarge them – like look like growing bigger – along with the other signs of malignancy
periapical scare
aka fibrous jealing
ay see pattern of healing bone
compare radiographs over time
clinical signs and symptoms take precendent
used to be a lesion
already had a root canal procedure!!
location of glandular odontogenic cyst
aka?
arises from?
anterior in mandible more likely
- will resemble an ameoloblastoma outline and ‘soap bubble’ appearance but this can CROSS MIDLINE
aka sailo-odontogenic cyst
- from odontogenic epithelium and includes mucous-producing salivary gland cells
40-50 years (differentiate it from CGCG) and female >male
focal osteoporotic bone marrow aka? mechanism?
AKA marrow space
normal hematopoietic or fatty marrow
- hperplasia of bone marrow
- embryonic remnants
- abnormal healing after extraction
- trauma, infectin
shows in middle aged woman more
focal osteoporotic bone marrow imaging features
empty marrow space and bone around is normal
- no trabeculation really and occurs in the posterior more / near apices/ edentulous spaces / furcation of molars
central odontogenic fibroma aka
clinical features
simple odontogenic fibroma and odontogenic fibroma (WHO type)
most between 11 and 39 years old
asymptomatic or swelling and tooth mobility , cleft or depression in the palate wher expansion would be expepcted
imaging features of central odontogenic fibroma
confusing one
WD, varying cortication
internal
- small are unilocular and large can be multilocular
INTERNAL SEPTA CAN BE FINE AND STRAIGHT OT GRANULAR
- RL or internal calcification
can cause expansion and root resorption
first sign could be a depression within the hard palate (cleft)
multilocular - fruit ot grape lie clusters? vitality test?
if it was inflammatory it would be?
Lateral Periodontal Cyst - BOTRYOID type
manibular pre-molar or canine area
should be vital
inflammation = lateral radicular cyst
** central hemangioma – careful because?
if drill into them can cause hemmorage
-aspiration produces blood
Central hemangioma
prolifersation of blood vessels, resembling a neoplasma, more of a harmatoma
most common in less than 10 years old, can occur later
bony hard swelling
can be painful, throbbibng, loosening and migration of teeth, bleeding from gingiva, mobility
central hemangioma most common where? looks?
within the IAC – can be WD, corticated ot simulate malignancy
SUNRAY periosteal reaction
- little round dots? coarse - trabecular pattern or occluations
osteogenic sarcoma usually presents as ?
sunray bone reaction
what should you do before opening central hemangioma lesino
ASPIRATE
central hemangioma mimics?
YES – like osteosarcoma, and other malignancies, multilocular lesions, and benign lesions, neural lesions
what to have on your differential with hemangioma
neural lesion
