Hydatid Cyst of the Cerebellopontine Cistern: Report of Two Cases with Literature Review.

Posterior fossa localization of a hydatid cyst is uncommon; in these cases, the cyst usually locates in the cerebellum. Localization within the subarachnoid spaces or the cerebrospinal fluid ventricular system is exceptional. In the present report, which appears to be the seventh in the literature, we describe two cases of a hydatid cyst in the cerebellopontine cistern.

Low-Grade Astrocytoma Causing Dural and Calvarial Destruction.

Most of the literature on intra-axial lesions causing calvarial and dural destruction comes from case reports for glioblastoma, lymphoma, metastasis, and aggressive meningioma. Destruction of dura and calvaria by low-grade gliomas is extremely uncommon; cases reported so far have been mostly oligodendrogliomas. This article describes the unusual case of a 23-year-old male patient with a left-sided intra and extracranial tumor involving the frontal lobe, destroying the overlying dura and calvaria, who underwent maximal safe resection.

Unilateral blindness following superior laryngeal nerve block for awake tracheal intubation in a case of posterior cervical spine surgery.

Background: Superior laryngeal nerve block (SUPLANEB) is a popular airway anesthesia technique utilized for successful awake endotracheal intubation in patients with significant cervical spine instability. If not performed by an expert, it carries the risk of general/neurologic complications that are typically minimal/transient. However, permanent blindness and/or upper cranial nerve neuropathies may occur.

Rare Case of Hydatid Cyst in the Cerebellopontine Cistern.

Posterior fossa localization of a hydatid cyst is uncommon; in these cases, the cysts usually grow in the cerebellum. Localization within the subarachnoid spaces or the cerebrospinal fluid ventricular system is exceptional. In the present report, which appears to be the sixth in the literature, we describe a case of a hydatid cyst in the cerebellopontine cistern.

Stereotactic Aspiration in Management of Rare Case of Tuberculous Cerebellar Abscess.

Tuberculous brain abscess is an extremely rare form of central nervous system tuberculosis. This lesion usually occurs in the supratentorial space. Cerebellar tubercular abscesses are rare.

Lipoma with Agenesis of Corpus Callosum: 2 Case Reports and Literature Review.

Background: Intracranial lipomas are extremely rare fat-containing lesions, comprising 0.1-0.5% of all primary brain tumors.

Sciatica caused by lumbar epidural gas.

Gas production as a part of disc degeneration can occur but rarely causes nerve compression syndromes. The clinical features are similar to those of common sciatica. CT is very useful in the detection of epidural gas accumulation and nerve root compression.

Benign chondroid syringoma of the orbit: a rare cause of exophtalmos.

Chondroid syringoma (CS) of the orbit is an extremely rare benign neoplasm. To the best of our knowledege, this is the second case reported in the english litérature.We report a case of a 41-year-old woman with orbital CS.

Posterior ring apophysis separation combined with lumbar disc herniation in adults: a 10-year experience in the surgical management of 87 cases.

Object: The association of posterior ring apophysis separation (PRAS) with lumbar disc herniation (LDH) is uncommon and represents a true subgroup of disc herniation mainly seen in the adolescent population. The objective of this study was to describe a decade of experience in the care of adult patients with PRAS with LDH, giving particular attention to its diagnosis, surgical treatment, and outcome.

Methods: This retrospective study focuses on a case series of adult patients with PRAS associated with LDH who underwent surgery for lumbar disc disease in the author's neurosurgical department between 1999 and 2008.

Dynamic CT scan of the craniovertebral junction: a role in the management of os odontoideum.

Os odontoideum is an uncommon abnormality of the cranio-vertebral junction (CVJ) that exists as a separate ossicle apart from a hypoplastic dens. Its genesis and natural history have been debated, and its proper treatment remains uncertain. A 48-year-old woman complained of persistent upper neck pain and paraesthesia of her left side.
