INTRODUCTION Facial nerve palsy results in the loss of facial expression and is most commonly caused by a benign self-limiting inflammatory condition, known as Bell's palsy. However, there are other conditions which may result in injury of the seventh cranial nerve and the radiologist should be familiar with their imaging appearances. MATERIALS AND METHODS The relevant anatomy of the facial n...

Aberrant regeneration of the third nerve occurs as a result of synkinetic 'miswiring' of the third nerve following its injury, such as in third cranial nerve palsy due to tumor, trauma, or aneurysm. The case presented is an elderly woman with new vertical diplopia, which led to a diagnosis of a third cranial nerve palsy, thought to be caused by a 5 mm blister aneurysm of the posterior communica...

Multi-segment Facial Nerve Schwannoma (MFNS) is a very rare tumor, benign in nature and can arise anywhere along the course of facial nerve from its origin cerebello-pontine angle to extra cranial ramification parotid space head neck. It mimic like vestibular schwannoma other schwannoma. The most common clinical presentation palsy depending upon segment involved. We report case multi-segment ex...

tuberculous meningitis (tbm) and acute bacterial meningitis (abm) cause substantial mortality and morbidity in both children and adults. identification of poor prognostic factors at patient's admission could prepare physicians for more aggressive monitoring of patients with meningitis. the objective of this study was to determine the predictive value of neurological features to differentiate ab...

SUMMARY We report a case of solitary fibrous tumor (SFT) causing isolated hypoglossal nerve palsy. The neuroimaging appearance of the tumor was indistinguishable from that of schwannoma or meningioma. Immunohistochemical tests demonstrated strong reactivity for CD34 but an absence of staining for S100 and epithelial membrane antigen; this profile is indicative of an SFT. SFTs are mesenchymal tu...

Cranial nerve palsy could be one of the presenting features of underlying benign or malignant tumors of the head and neck. The tumor can involve the cranial nerves by local compression, direct infiltration or by paraneoplastic process. Cranial nerve involvement depends on the anatomical course of the cranial nerve and the site of the tumor. Patients may present with single or multiple cranial n...

during last decades many researchers have focused on the conditions associated with bell's palsy including diabetes mellitus, hypertension, and viral infections. this study was performed to evaluate correlation of diabetes mellitus and bell's palsy and some relevant features not discussed in the literature in an iranian population. the presence of diabetes mellitus was evaluated in a total numb...

We describe isolated cranial nerve-III palsy as a rare clinical finding in a patient with perimesencephalic subarachnoid hemorrhage. In this unusual case, the patient presented with complete cranial nerve-III palsy including ptosis and pupillary involvement. Initial studies revealed subarachnoid hemorrhage in the perimesencephalic, prepontine, and interpeduncular cisterns. Angiographic studies ...

CASE REPORT To describe a case of combined bilateral cranial nerve palsy of traumatic origin. To determine the lesions that produce the symptoms is useful to define the final prognosis and the best treatment. DISCUSSION We report the case of a patient who developed a bilateral sixth nerve and left third nerve palsy after head trauma. The underlying lesion was a diffuse axonal injury. After an...
