Thailand's 88-year-old king, the world's longest-reigning monarch, is recovering after being treated last month for "water on the brain" and narrowing of the arteries.
King Bhumibol Adulyadej has been treated for various ailments during the past year in hospital in Bangkok, the Royal Household Bureau said on Sunday.
He was last seen in public on January 11, when he spent several hours visiting his palace in the Thai capital.
Anxiety over the king's health and the succession has formed the backdrop to more than a decade of political upheaval that has included two coups and sometimes-violent street protests.
An X-ray showed the king had "a lower amount" of cerebrospinal fluid surrounding his brain after a build-up was drained last month, the palace statement said.
Echocardiograms showed a "satisfactory function of the king's heart muscles", it said, adding the king occasionally had a mild fever and was recovering from it.
News about the royal family is tightly controlled in Thailand. Laws protecting the royals from insult make it a crime to defame, insult or threaten the king, queen, heir to the throne or regent.
