Morphology
sinus + sigmoideus
The phrase is a straightforward composition of 'sinus' (venous channel) and 'sigmoideus' (Latin/medical form of 'sigmoid', meaning S-shaped), so the overall meaning 'S-shaped venous channel' is directly derivable from the constituents. Although the term is specialist and uses Latin word order, that does not obscure the compositional relation—if a learner knows both constituent meanings the MWE is immediately understandable.
Etymology
Sinus sigmoideus comes from Latin words: sinus meaning 'bay' or 'channel' and sigmoideus meaning 'S-shaped'. So the name paints an image of an S-shaped channel in the skull that drains blood from the back of the brain.
