A gynaecologist who performed surgery without waiting for a report on a specialist scan or seeking help from a radiologist has been found guilty of professional misconduct.

Duncan Leung Sau-sun was charged with operating on Yvonne Tsang Yee-wan to remove an ovarian cyst on December 2, 2003, 'when he did not have proficiency in interpreting MRI films'.

On November 25 that year, Ms Tsang had complained that she had a swollen left leg, the Medical Council was told.

Dr Leung told her she required a kidney X-ray. The clinic called her the next day to discuss the findings.

She was told the X-ray indicated she could have a dermoid cyst, also known as ovarian teratoma, on her left ovary. Dr Leung told her she required an ultrasound.

When the test gave a similar finding, he advised her to undergo the computer-assisted tomography (CAT) scan and have the cyst removed as soon as possible. But several attempts at performing a CAT scan failed, so a magnetic resonance imaging scan (MRI) was done instead, the Medical Council heard.

On December 2, Dr Leung performed surgery on Ms Tsang without waiting for the MRI report or a consultation with a radiologist.

In previous hearings, the council heard that Dr Leung interpreted red markings made by crayon on the MRI reports as indicating an abnormality.

He also believed the ultrasound permitted him to diagnose the dermoid cyst, and the MRI scan was to determine other problems.

Dr Leung admitted his wrong clinical judgment had led to a misdiagnosis of the cyst.

But he claimed the error was in good faith.

But council chairwoman Felice Lieh Mak said Dr Leung's decision to take the crayon marks as indicating abnormalities was unacceptable.

The council also found Dr Leung should not have proceeded with the operation without consulting the radiologist on the MRI scan.

The council said that given that Dr Leung had learned his lesson, and the chances of reoffending were slim, he would only be reprimanded.
