- Cyst with a dot sign
The cyst with dot sign is seen in neurocysticercosis and represents the parasitic cyst with, usually eccentric, scolex.
It can be seen on both MRI and CT at:
- the vesicular stage (CSF density / intensity cyst - denser / hyperintense scolex) and
- colloidal vesicular stage (enhancement of wall and scolex)
It should not be confused with the dot that can be seen in a Rathke cleft cyst.
