Intrapancreatic accessory spleen mimicking malignant tumor: three case reports.

Intrapancreatic hypervascular lesions may represent metastases, neuroendocrine tumors, or intrapancreatic accessory spleens. The benign intrapancreatic accessory spleen can be difficult to separate from a malignant neuroendocrine tumor or metastasis. We report three cases of pancreatic lesions that underwent pancreatic surgery due to suspicion of malignancy on imaging; all cases were histologically intrapancreatic accessory spleens. Our cases point to the importance of performing single-photon emission computed tomography with heat-damaged Tc-99m-pertechnetate labelled erythrocytes to identify splenic tissue, even though small lesions can show a false-negative result.

[Malignant lymphoma complicated with posterior reversible encephalopathy]. / Posterior reversibel encefalopati efterbehandling af malignt lymfom

We present a 56-year-old woman who received chemotherapy for relapsed diffuse large B-cell lymphoma and developed posterior reversible encephalopathy syndrome (PRES) with generalized seizures 27 days after treatment with rituximab, ifosfamide, carboplatin and etoposide (R-ICE). The patient had moderate renal impairment (eGFR > 30 ml/min.) and a normal blood pressure. PRES was confirmed by MRI, which showed oedema of the occipital, parietal and frontal lobes. A control MRI after four weeks showed full remission. To our knowledge this is the first published case of R-ICE causing PRES.
