Challenging REGEX Problem to Address Medical Results Abstraction

Question

I have been unable to formulate a regular expression to extract the 1, 1S, 2, 2S, 3, 3S, 4A, 4AS, 4B, 4BS, 4X, 4XS and the potential add on of C to those multiples as well, from the Lung Rads Catagory in unstructured radiology reports, where the language may look like :

LUNG RADS CATEGORY 2
Lung RADS category 1, 
Lung RADS category 2. 
LUNG RADS CATEGORY 1
Lung RADS 3S.
Lung RADS Category 1:
Lung RADS Category 1 (S):
LUNG RADS CATEGORY 1 S
Lung RADS category: 2S.
Lung RADS: 2C
Lung RADS category 4B,
Lung RADS category 1S.
Lung RADS: 3.
Lung RADS category I
Lung RADS 2
LUNG RADS CATEGORY:I
LUNGRADS 2
LUNGRAD 2
LUNG-RAD 3
