Osteosarcoma of the skull is a very rare condition. Moreover, it is extremely rare for osteosarcoma to present as multiple lesions confined to the skull. A 58-year-old woman was admitted with two masses in the parietal area of the skull, accompanied by mild headache and tenderness. Imaging revealed two masses with a heterogeneous consistency in the cranial bones. Excision craniectomy was perfor...

Twenty-five patients with tumors in the region of foramen magnum confirmed by pathology and surgery are presented. There were 19 males and 6 females. The ages ranged from 4-56 years. According to the clinical findings, the authors suggest that if a patient has occipitocervical pain or headache accompanied with neurological signs of medulla, cervical spinal cord or lower cranial nerves, tumors i...

Surgical approaches to the inner ear and internal auditory canal (IAC) are widely known and extensively recorded. The most popular can be classified as retrosigmoid, transmastoid-translabyrinthine, and middle cranial fossa approaches. For the first time, an exclusive endoscopic approach to the IAC is described here, used to remove a cochlear schwannoma involving both the IAC and labyrinth. The ...

Benign triton tumors (neuromuscular hamartomas) are rare neoplasms composed of well-differentiated striated muscle fibers admixed with peripheral nerve fibers. To the best of our knowledge, this is the third case reported in the world literature of a benign triton tumor involving cranial nerve V (trigeminal nerve) and the first in the radiology literature. The previous reports of this lesion ha...

cranial neoplasms seldom calcify and classic histopathological series has revealed the incidence of calcification in brain metastasis to be just about 1% (Sastre-Garriga et al., 2000); furthermore, development of breast cancer in men is a rarity. A 30-year-old man with two year history of breast cancer and chemotherapeutic treatment was admitted in emergency room for the evaluation of moderate ...

Objective: We aimed to study the leprosy cranial Magnetic Resonance Imaging (MRI) findings and cerebral pathology. Methods: A total of 20 patients with leprosy who underwent MRI findings were presented. Results: Nonspecific senile atrophic changes were observed in most of patients with leprosy. Furthermore; meningiomas was observed in three patients with leprosy and chronic dural venous sinus t...

The sixth cranial nerve runs a long course from the brainstem to the lateral rectus muscle. Based on the location of an abnormality, other neurologic structures may be involved with the pathology related to this nerve. Sixth nerve palsy is frequently due to a benign process with full recovery within weeks, yet caution is warranted as it may portend a serious neurologic process. Hence, early dia...

We report a rare case of acute respiratory failure in a previously asymptomatic patient showing clinical signs of inferior cranial nerve palsy together with weakness and muscular atrophy of the upper limbs. Magnetic resonance imaging revealed Arnold-Chiari malformation associated with platybasia, basilar impression, syringomyelia and Klippel-Feil syndrome. Episodes of apnoea required tracheosto...

Disorders of ocular motility may occur after injury at several levels of the neuraxis. Unilateral supranuclear disorders of gaze tend to be transient; bilateral disorders more enduring. Nuclear disorders of gaze also tend to be enduring and are frequently present in association with long tract signs and cranial nerve palsies on opposite sides of the body. Nystagmus is a reliable sign of posteri...

A young girl developed an intracranial abscess and necrotizing cellulitis following penetrating injury from a lawn dart. Initial identification of a gram-positive rod growing aerobically from clinical specimens was as a Bacillus organism, but the observation that the isolate grew poorly in subcultures for susceptibility testing but quite well under standard anaerobic culture techniques led to t...
