I wanted to write a comment, but apparently you need 50 reputation for that. Sorry for the (almost) duplicate.
I was happy to find my question has been asked and answered on this site. I was less happy to find out that I couldn't replicate the result.
I also have a follow up question: in my case there is a non-standard plural (my longer acro is high resolution computed tomography). How can something like this be modified to support that?

\begin{document}
\begin{acronym}
\acro{CME}{Coronal Mass Ejection}
\acro{ICME}{Interplanetary \acx{CME}}
\end{acronym}
\section{Text}
\acresetall
The \ac{ICME} is a version of \ac{CME}.
\acresetall
A version of \ac{CME} is called \ac{ICME}.
\end{document}
still resulted in the following output:
The Interplanetary Coronal Mass Ejection (ICME) is a version of Coronal Mass Ejection (CME). A version of Coronal Mass Ejection (CME) is called Interplanetary Coronal Mass Ejection (ICME)
I'm using ShareLaTeX, but I have the same result on TexMaker+MikTeX. Is there something I'm missing? How can I get the result I want?
