The clinical events and the type and duration of interventions from the emergency department admission onward are reported in  Table 1  and  Figure 1 . Serum amylase and lipase levels were recorded during the whole clinical course, and no correlation was shown with the severity of pancreatitis ( Figure 1 ).
The baseline abdominal CT scan (A) shows findings of pancreatitis and a multiloculated fluid and hemorrhagic collection in the pancreatic tail, with a maximum size of 6.5 cm x 5 cm. After 16 weeks since the last dose of rituximab, CT scan (B) shows complete resolution of pancreatitis, with homogeneous pancreatic parenchyma and fluid collection.

A CT scan showed worsening of the known pancreatic fluid collection with hemorrhagic development ( Figure 2 ). On the following admissions, no finding of pancreatitis was detected on the CT scan ( Figure 2 ).
