HighlightsA very rare case of paraganglioma of filum terminale is described.Clinical and radiological features of spinal paraganglioma are listed.Surgical management of paraganglioma of filum terminale is discussed.

During craniotomy, hemostatic materials such as oxidized cellulose and cotton pads, commonly used to control bleeding, may cause a granulomatous reaction that may produce spaceoccupying mass lesions termed textiloma (or gossypiboma). We present a 46-year-old female who underwent a right frontotemporal craniotomy and surgical removal of intraparenchymal cerebral hemorrhage, and who developed a textiloma during the postoperative period causing seizures. Granulomatous reactions due to hemostatic agents have been reported experimentally, as well as after cranial and spinal operations. We emphasize that although it is rare, an adverse reaction such as a postoperative textiloma due to hemostatic material and subsequent granuloma formation can result in a false image of rebleeding, tumor recurrence, radiation necrosis, or postoperative abscess, depending on the particular clinical history of each patient.

Dermoid cysts are rare benign lesion of ectodermally origin containing dermal elements, including sebaceous glands, sweat glands, and hair follicles and rupture of dermoid cyst whit dissemination of intracystic content is very rare. We present a case of a 43-year-old female presented with head injury after a sudden loss of consciousness. Radiological examination showed an ovalar cystic lesion in left frontal region with hydrocephalus. A left frontal craniotomy for removal of the tumor was performed and histological examination revealed a dermoid cyst. We discuss the clinical and radiological feature and treatment of this case.

HighlightsIn literature there are still many controversies about the management of multiple aneurysms.A series of 19 cases of multiple aneurysms for a total of 44 aneurysms, of which 43 surgically treated, is described.Surgical management of multiple aneurysms of is proposed.

Background:Von Hippel–Lindau (VHL) disease is an autosomal dominant condition characterized by formation of multiple benign and malignant tumors. In this disease supratentorial lesions are rare and no falcine meningioma has been previously reported. Differential diagnosis is very difficult and the histopathological examination is the definitive method for diagnosis.Case Description:A patient with VHL underwent a suboccipital craniotomy for removal of cerebellar hemangioblastoma and after 2 years magnetic resonance imaging (MRI) showed an iperintense solid mass located at posterior part of the falx. Histological diagnosis revealed meningioma.Conclusion:The only case in the literature of falcine meningioma in a patient with Von Hippel–Lindau disease, discovered during radiological follow-up, is described and a surgical management is proposed.
