Imaging of extraventricular neurocytoma: a systematic literature review.

Objective: Extraventricular neurocytoma (EVN) was firstly described in 1997. The current literature regarding imaging of EVN is limited to sporadic case reports and case series. EVN is still poorly considered in the differential diagnosis by neuroradiologists, thus diagnosis remains challenging.

Recurrent Epistaxis of Unknown Origin: the Role of Imaging.

We report two cases of patients who presented to the Emergency Room (ER) with a history of recurrent epistaxis. Conservative treatment was provided to both patients and the most common causes of bleeding were excluded. Patients underwent radiological examinations that revealed the presence of an Intracavernous Carotid Artery Aneurysm (ICAA) extending into the sphenoid sinus through the erosion of postero-lateral bony wall.

Post-Traumatic Intracranial Dislocation of Unfractured Mandibular Condyle.

We present a case of post-traumatic intracranial dislocation of an unfractured mandibular condyle in a 17-year old female patient associated with multiple skull base fractures. Computed tomography (CT) findings are illustrated, and also postoperative CT is described. The article underlines the pivotal role of CT in the early diagnosis and in the investigation of additional brain lesions and complications.

Atypical Extraventricular Neurocytoma: Imaging Findings of Disregarded Diagnosis.

Extraventricular neurocytoma (EVN) is an exceedingly rare brain tumor. The radiologic and histologic features of EVN are insidious, and only a few reports and clinical cases describe the characteristics of the tumor, which may show different presentations. We report a case of atypical EVN in a 23-year-old man; Computed Tomography and Magnetic Resonance Imaging features of the mass are described, and differential diagnosis are illustrated.

Imaging of cranial nerves: a pictorial overview.

The human body has 12 pairs of cranial nerves that control motor and sensory functions of the head and neck. The anatomy of cranial nerves is complex and its knowledge is crucial to detect pathological alterations in case of nervous disorders. Therefore, it is necessary to know the most frequent pathologies that may involve cranial nerves and recognize their typical characteristics of imaging.
