De Novo Intra-neural Arachnoid Cyst Presenting with Complete Third Nerve Palsy: Case Report and Literature Review.
Intraneural arachnoid cyst is an extremely rare etiology of isolated cranial nerve palsy. Although seldom encountered in clinical practice, this pathology is amenable to surgical intervention. Correct identification and treatment of the cyst are required to prevent permanent nerve damage and potentially reverse the deficits. We describe a rare case of isolated third nerve palsy caused by an intraneural arachnoid cyst. ⋯ To our knowledge, this is the first report of an intraneural arachnoid cyst causing isolated third nerve palsy. This rare pathology proves to be both a diagnostic and therapeutic challenge.

Review Case Reports
The Affinity of Mucormycosis for the Basal Ganglia in Intravenous Drug Users: A case illustration and review of the literature.
Central nervous system mucormycosis is an aggressive fungal infection often ending in fatality. The usual circumstance is an immunocompromised individual presenting with rapidly progressive rhinocerebral involvement. An extremely rare variant of central nervous system mucormycosis isolated to the basal ganglia in an immunocompetent intravenous drug user is detailed in this manuscript. The patient was aggressively treated with aspiration of the fungal abscess and long-term intravenous antifungal agents.

Review Case Reports
First case of primary sellar/suprasellar intraventricular Ewing Sarcoma: case report and review of literature.
Intracranial Ewing sarcoma (ES) and peripheral primitive neuroectodermal tumors (pPNETs) are extremely rare and poorly differentiated neoplasms. Immunohistochemical and cytogenetic findings support the possibility of a unique nosologic entity. Primary intracranial localization of this tumor is extremely rare; a few cases are reported in the literature, with only some confirmed by genetic studies. ⋯ To our knowledge, this is the first case of primary intrasellar/suprasellar-intraventricular ES/pPNET confirmed by molecular genetic analysis. Extensive investigations, including pathologic, immunohistochemical, and genetic studies, are needed for differentiation of these tumors from other, more common sellar/suprasellar tumors. Our case highlights that an interdisciplinary therapeutic approach is mandatory to guarantee a favorable outcome.

Cervical ribs have been reported to be present in about 0.5% of the general population, 10% of patients with cervical rib who are symptomatic usually have neurogenic symptoms, but some have arterial symptoms. In 1861, Coote was the first to excise a cervical rib through a supraclavicular approach and relieved the symptoms of thoracic outlet syndrome. ⋯ A modified supraclavicular interscalene approach for resection of symptomatic cervical ribs has been shown to be effective in the treatment of neuralgic pain. Compared with other approaches, it proved to be less invasive, with small transverse incision and without resection of scalenus anterior muscle.

Review Case Reports
Endoscopic Removal of Suprasellar Colloid Cyst with Interpedincular and Prepontine Cisterns Extension.
Colloid cysts (CCs) are rarely found in the sellar-suprasellar region. Differential diagnosis of CCs is more challenging in this region because many other cystic lesions may locate or invade sellar or suprasellar structures. We present a large and unusual case of sellar-suprasellar CC with extension into the suprasellar, interpeduncular, and prepontine cisterns. This is the first case of sellar-suprasellar CC treated with an endoscopic transsphenoidal approach. ⋯ Although rarely found in this location, CC should be considered in the differential diagnosis in patients who present with a sellar-suprasellar cystic lesion. Additionally, sellar-suprasellar CC would be a good candidate for the endoscopic endonasal approach.
