here's a quote from Chris WunderLee's novella, The Loony:

"Albert was back in New England, long since forgetting his plunge into the Pacific, and beginning what was already a controversially castrophenic career..."

this seems to be a nonce-word (or non-word), but I'm guessing it's meant to mean:
1) 'military', as in Albert's (tenuous) connection to the M-I complex, (see castrametation, the making of a military camp; fr. L. castrum, fortified place)
2) possibly to be confused with castrophrenia*, relating to the belief that one's thoughts are being stolen, *itself of some dubiety
3) just another nonce word,
4) none/all of the above.

NB: WunderLee seems to be a tad Joycean with his wordplay.
