"T1: typically hypointense (unless complicated by recent haemorrhage)"
"T2: hyperintense"
"T1 C+ (Gd): enhancement is typical, and is usually centrifugal (from centre outward)"
"Complications "
"azathioprine, methotrexate, 6-mercaptopurine (6-MP), 6-thioguanine (6-TG)"
"Hodgkin lymphoma, multiple myeloma"
"infection in AIDS: bacillary peliosis caused by Bartonella henselae, Bartonella quintana and Rochalimaea henselae"
"Treatment depends on the cause. When a causative drug/toxin is suspected, withdrawal of that agent may result in resolution. If seen in the setting of HIV/AIDS, antibiotic treatment may be effective in eradicating B. henselae. If focal and haemorrhagic, resection may also be beneficial 1."
"globular discontinuous contrast enhancement tends to be centripetal (periphery first) rather than centrifugal (centre first)"
Expected headings
"Complications "
"Following contrast administration, there is usually globular centrifugal (more common) or centripetal arterial enhancement with no washout, the lesion remaining slightly hyperattenuating compared to surrounding liver on portal venous phase 1. Enhancement may be uniform or peripheral or irregular, but in contrast to cavernous haemangioma, it is usually continuous. There is no mass effect on neighbouring hepatic vessels 6."
"Signal characteristics may be altered due to the presence of haemorrhage; however, in general:"
"when typical, are easy to distinguish: central scar; homogeneous arterial enhancement (except for scar); delayed enhancement of the scar; isoattenuating on portal venous phase; strong enhancement on hepatobiliary phase"
