Apollo 8's orbital Hasselblad AS08-12-2195 shows a rather distant view of Lacus Solitudinis and adjacent crater Bowditch.
Apollo 15's oblique south-looking orbital Fairchild metric/mapping camera frame AS15-M-2498 shows much of Lacus Solitudinis's southern half at the foreground (the dark region nearby).
Lacus Solitudinis is also recognizable in the series of TEC-photographs made during Apollo 17 (A17 Revolution TE).

Lacus Solitudinis and nearby crater Bowditch are described and depicted in APOLLO OVER THE MOON: A VIEW FROM ORBIT, Chapter 7: Unusual Features (Part 1), Figure 230.

The name Lacus Solitudinis sounds a bit like Palus Solitatis, which could have been the official name of the low-albedo region near crater Andersson, at centre of the Mendel-Rydberg Basin. Unfortunately, this name was not approved by the IAU. See page Luna Incognita.
