Most cases of pancreatoblastoma, a rare malignant epithelial tumor of the pancreas, are seen in the pediatric population. The rarity of pancreatoblastoma, the similar radiologic findings to those seen in other pancreatic lesions, and its histopathologic heterogeneity, make its preoperative diagnosis in adults a real challenge. We report ultrasound, computed tomography and magnetic resonance imaging correlative findings of a histologically proven pancreatoblastoma in a 37-year-old woman. Pancreatoblastoma should be considered in the differential diagnosis of a pancreatic mass presenting uncommon imaging features.

Schwannoma is a benign tumour that arises from Schwann cells of the peripheral nerve sheath, and is a common tumour of the head and neck. However, intraoral location is very uncommon (only 1% of all head and neck schwannomas).We report a rare case of lingual schwannoma in a 20-year-old male patient who presented with a small, slow-growing mass over the right lateral border of the tongue with 1 year of evolution and that became recently ulcerated. The patient underwent MRI examination and complete surgical excision. Histopathological and immunohistochemical examination confirmed the diagnosis.

Cryptococcal meningoencephalitis (CM) remains a common cause of central nervous system infections. Patients usually present with headache, fever, malaise, and altered mental status over several weeks. Signs are often absent, but they may include meningism, papilledema, cranial nerve palsies, and depressed level of consciousness. Individuals with CM can occasionally present with small vessel vasculitis causing cerebral lesions. The literature regarding patterns of cerebrovascular injury in CM is scarce. We describe a case of CM in which an unusual presentation was observed: transient focal neurological symptoms initially with absence of fever that led to a misleading primary diagnosis of transient ischemic attack. Since neurological symptoms may be a manifestation of a cryptococcal infection, it is necessary to have a high degree of suspicion for this pathology in the presence of focal neurological deficits, even in patients with vascular risk factors, requiring a thorough etiological investigation.

Pancreatic dorsal agenesis (PDA) is a rare congenital anomaly, usually asymptomatic, that can present with abdominal pain, pancreatitis, diabetes mellitus and jaundice. Pancreatic tumours in PDA background are extremely rare, and when they occur are mainly pancreatic ductal adenocarcinoma. We present a case of a 48-year-old female patient with incidental detection of a 26×20 mm nodular lesion of the cephalic pancreas on ultrasound. Surgery was performed and gross examination revealed PDA with a tumour developed around the Wirsung duct. Histology showed a neuroendocrine tumour G1 with neural and vascular invasion. Two and half years later, the patient is alive and without tumour relapse. Awareness of the association of PDA and pancreatic tumours is fundamental in order to develop personalised follow-up programmes.
