This document discusses the clinical manifestations and radiographic features of odontogenic keratocysts. It notes that odontogenic keratocysts typically present as slow-growing, painless tumors that can cause facial deformity and jaw expansion as they enlarge. Radiographically, they can appear as unilocular, spider-web, honeycomb, or soap-bubble patterns depending on the presence and arrangement of radiolucent areas and bony trabeculae. Advanced stages may show thinning of the cortical bone and extension into soft tissues or sinuses.

12. Clinical manifestations
 A slow growing tumor, painless
 Early stages: asymptomatic, discovered incidentally
 Enlarges- Facial deformity, expansion of jaw bone
 Expansion ( bony hard, non-tender, ovoid or fusiform)
 Advanced stages: Egg shell crackling (thinning of
cortical plate)
 May extend into soft tissue
 Maxillary lesion – extend into sinus
 Tooth mobility (may be)

19. Radiographic Features
 According H. M worth it can
present with Four
radiographic appearances
 UNICYSTIC
 Unilocular radiolucency~
cyst.
 However, unlike cyst, it
causes a break or
discontinuity in the peripheral
cortex and may even show
trabeculae within the lumen

20. • SPIDER-WEB , where the lesion is seen as a large
radiolucent area with scalloped borders.
• From the center of the lumen coarse strands of
trabeculae radiate peripherally, giving rise to a gross
caricature of a spider

21.  HONEY-COMB
 Multilocular radiolucency
with large compartments
of varying sizes, giving
rise to the soap-bubble
appearance, or a multi-
chambered or multi-cystic
'bunch of grapes'
appearance.

22. • SOAP-BUBBLE
• Beehive pattern.
• These are tumors that have not undergone cystic
degeneration.
• Hence, multiple small radiolucencies are seen
surrounded by hexagonal or polygonal thick-walled
bony cortices, giving rise to a honeycomb appearance.

Unilocular, radiolucent, pericoronal a/w tooth
Multilocular, radiolucent associated with tooth
