Prognostic Factors of the Primary Central Nervous System Lymphoma: Clinical Experience from a Tertiary Care Center in the Middle East.

 Primary central nervous system lymphoma (PCNSL) is a rare extra nodal non-Hodgkin's lymphoma. The optimal treatment for PCNSL is still unclear. In this study, we present our experience with management of PCNSL in a tertiary care center in Iran.

Initial Experience with Diffusion-weighted Imaging to Predict the Tumor Consistency and Surgical Success in Solid Growth Hormone Producing Pituitary Macroadenomas.

Background: Tumor consistency is an important factor impeding transsphenoidal resection of some pituitary macroadenomas. Preoperative prediction of the tumor consistency may help neurosurgeons in preparing the patients for other therapeutic options after a subtotally resected growth hormone (GH)-producing macroadenoma. We present the preliminary results of our study about the application of the preoperative diffusion-weighted (DW) magnetic resonance imaging (MRI) to predict the consistency and resection rate of GH-producing pituitary macroadenomas.

Pituitary Apoplexy during Treatment of Prolactinoma with Cabergoline.

Pituitary apoplexy is a rare clinical presentation caused by infarction of the pituitary gland or adenoma with or without hemorrhage. Although pituitary apoplexy is usually spontaneous, one of the predisposing factors is treatment with dopamine agonists, especially bromocriptine. The occurrence of apoplexy during cabergoline therapy is reported much less frequently.

'Coexisting pituitary adenoma and suprasellar meningioma-a coincidence or causation effect: report of two cases and review of the literature'.

Coexistence of pituitary adenoma (PA) and another type of brain tumor is a very rare clinical scenario. Even though such a presentation can be an incidental event but a thorough review of the literature will be made to elucidate the possible mechanisms and treatment options in similar cases. Two cases of concomitant sellar and suprasellar/diaphragmatic tumors are reported.

Masticatory ability with depression, anxiety, and stress: Does there exist any association?

Background: Masticatory ability as a subjective response to masticatory function indicates patients' perception of their mastication. To the best of our knowledge, there has been no study on association between masticatory ability and psychological status. This study investigated the association between self-assessed masticatory ability (SAMA) and psychological status among a large sample of Iranian adults.

Impact of electrolyte imbalances on the outcome of aneurysmal subarachnoid hemorrhage: A prospective study.

Background: Electrolyte disturbances are frequently observed during the acute and subacute period after subarachnoid hemorrhage (SAH) and may potentially worsen therapeutic outcome. This study was conducted to determine the pattern of electrolyte disturbance in the acute and subacute phase after SAH and their effect on the long-term outcome of the patients.

Materials And Methods: Fifty-three patients were prospectively enrolled.

Predictive value of diffusion-weighted MRI for tumor consistency and resection rate of nonfunctional pituitary macroadenomas.

Backgrounds: Firm tumor consistency is one of the most important factors that impede sufficient removal of pituitary macroademoas via a transsphenoidal approach. The utility of diffusion-weighted (DW) magnetic resonance imaging (MRI) in predicting the tumor consistency and successfulness of transsphenoidal resection was evaluated in this study.

Methods: Thirty consecutive primary cases of nonfunctional pituitary macroadenomas were prospectively enrolled.

Extracranial aneurysm of the distal PICA presenting as isolated fourth ventricular hemorrhage: case report and literature review.

Background: Posterior inferior cerebellar artery (PICA) aneurysms are relatively uncommon, comprising only 0.5-3% of all intracranial aneurysms. Distal PICA aneurysms are much more uncommon, with more than 200 cases being reported in the literature.
