Pituitary tumour presenting with trigeminal neuralgia as an isolated symptom

Invasion of the cavernous sinus by pituitary adenoma may cause involvement of cranial nerves III, IV, V and VI. However, trigeminal neuralgia as an isolated, initial symptom is very unusual. A patient with a pituitary adenoma, who had intractable trigeminal neuralgia as the only complaint which resolved following surgical removal is presented

Neuronavigation-Guided Endoscopic Endonasal Excision of an Intraorbital Intraconal Cavernous Hemangioma

A 50-year-old man presented with the complaints of gradual decrease of visual acuity in his left eye since 2 years. Brain magnetic resonance imaging revealed a left intraorbital intraconal round mass lesion consistent with cavernous hemangioma. Binostril endoscopic endonasal approach was performed with the aid of neuronavigation. The lesion was well capsulated and easily dissected and resected totally without complication. Early postoperative course was uneventful. Three-month follow-up after surgery revealed that the visual acuity and visual fields of the patient were normalized, and magnetic resonance imaging demonstrated total excision of the lesion

Pituitary Stone: A Case Report and Review of the Literature

A 39-year-old male without any significant complaints or symptoms presented with a calcified lesion located at the sellar region.Total removal of the lesion has been achieved via an endoscopic endonasal transsphenoidal approach. Histopathological examination of the lesion revealed a pituitary stone

Extended Endoscopic Endonasal Approach to the Clival Region

Objective: The objective of this study was to recognize the endoscopic anatomy of the clival region of the skull base and its neurovascular relations, which will make us able to perform safer and minimal invasive endoscopic approaches to this region with lower rate of complications

Anaplastic oligoastrocytoma: previous treatment as a possible cause in a child with acute lymphoblastic leukemia

The authors present a 14-year-old patient who developed an anaplastic oligoastrocytoma of the left parietal lobe 9 years after a successful treatment of acute lymphoblastic leukemia (ALL). He had a history of induction chemotherapy, intrathecal methotrexate and prophylactic whole brain irradiation (1,800 cGy in 10 fractions over 2 weeks)

Pituitary stone: a case report and review of the literature

A 39-year-old male without any significant complaints or symptoms presented with a calcified lesion located at the sellar region.Total removal of the lesion has been achieved via an endoscopic endonasal transsphenoidal approach. Histopathological examination of the lesion revealed a pituitary stone

Pneumatization degree of the anterior clinoid process: a new classification

The objective of this study is to determine the incidence and degree of anterior clinoid process pneumatization, in addition highlighting to their clinical significance. Multidetector-row CT scans of the skull base were reviewed in 648 subjects between 2007 and 2008. The presence of pneumatized anterior clinoid process and its degree were studied and documented. These datas were istatistically analyzed. Pneumatization of the ACP was found in 62 of 648 patients (9.6%) including 32 (51.6%) men and 30 (48.4%) women. The age of these patients ranged from 21 to 82 years (mean, 41 +/- 15.7 years). Pneumatization of the ACP occurred only on the left side in 14 cases (22.6%), only on the right side in 11 cases (17.7%), and bilaterally in 37 patients (59.7%). ACP pneumatization Type I, in which less than 50% of the ACP is pneumatized, was found in 47 of 124 sides (38%), Type II, in which more than 50% but not totally pneumatized ACP, was found in 28 of 124 sides (22.6%), and Type III, in which the ACP is totally pneumatized, was found in 22 of 124 sides (17.7%). The incidence of Type I in the general population was 6.6%, Type II was 3.5%, and Type III was 2.5%. Radiologically recognizing the degree of ACP pneumatization is important in decreasing the incidence of surgical complications during anterior clinoidectomy. Proper intraoperative management can be undertaken with special attention to the new classification
