METHODS Data of 55 patients macroadenoma presented to the with non-functioning pituitary Clinical Oncology and Nuclear Medicine department between 1998 and 2009 were investigated. RESULTS The most common symptom was visual disturbance （38.2%） followed by headache （27.3%）. The presence of male predominance was observed （1.4：1）. Ten patients received radio-therapy （RT） only. Extrasellar extension was the more common treatment. The overall response rate was 72.8% with completed response at 16.4%. Memory and intellectual sequelae were the most common late complications of treatment （14%）. The ten-year PFS was at 84.6%. PFS was found to be significantly better with higher dose of RT （up to 54 Gy）, treatment by both surgery and RT, absence of visual field defect, and tumor localized to sella, whereas it was not significantly affected by age and sex. CONCLUSION The data confirmed that the prevalence of mass effect and hypopituitarism in patients with non-functioning pituitary macroadenoma is elevated. Conventional external RT up to 54 Gy is safe and effective in controlling non-functioning pituitary macro- adenoma with tolerable and acceptable morbidity.展开更多

Although NFMAs are benign in origin, mass effects may lead to serious clinical symptoms such as visual impairments, chronic headache, and pituitary insufficiency. The authors describe a 51-year-old woman who had a NFMA (35 × 24 × 25 mm). The vision was reduced to 7/10 in the both eyes. A transnasal transsphenoidal surgery was performed and the tumor was successfully resected. Postoperatively, the patient had visual (9/10) and headache improvement. This case highlights a rare presentation of non-functioning pituitary macroadenoma.展开更多

Patients and Methods: From 2009 to 2013, 225 patients underwent EET surgery for sellar tumor. Among them, 168 suffered from visual disorders induced by chiasmatic compression, of which 88 met the inclusion criteria for this study. Average duration of follow up was 1.8 yrs ± 0.4 yrs. All patients had sellar MRI before surgery and yearly postoperatively, visual acuity (VA) and/or visual field (VF) measurements before, 3 months after surgery and yearly postoperatively. Results: All tumors were macroadenomas with a mean preoperative MRI-estimated volume of 10.0 {plus minus} 9.07 cm<sup>3</sup>. Preoperative VA was impaired with an average of 0.43 ± 0.13 LogMAR (left eye) and 0.36 ± 0.14 LogMAR (right eye) and VF was disturbed in 99% ± 2% of the cases with the most frequent disorder being bitemporal hemianopsia (38 patients). Post-operatively, the mean residual MRI-estimated tumor volume was 3.15 ± 3.71 cm<sup>3</sup>. Mean tumor volume reduction was 62% ± 9% (p < 0.001). Optic chiasmal compression resolved in 72% ± 10% of the cases. Visual function improved in 86% ± 7% of cases (p < 0.001). Conclusion: Endoscopic endonasal management of pituitary gland neoplasms is effective to reduce tumor volume. This technique achieved significant visual improvement in the majority of cases presenting with chiasmal compression syndrome.展开更多

文摘Background Pituitary apoplexy is a neurosurgical emergency and is a known yet rare complication of pituitary macroadenoma.Patients typically present with visual field defects,headache and altered sensorium.There are multiple risk factors for this complication and a thorough drug history is essential to exclude iatrogenic causes of disease.We present an extremely rare case of newly diagnosed pituitary insufficiency unveiled by ibrutinib therapy(a Bruton tyrosine kinase inhibitor).Furthermore,after initial withdrawal of ibrutinib because of the erroneous diagnosis of Syndrome of Inappropriate Antidiuretic Hormone Secretion(SIADH),its re-administration led to the development of classical pituitary apoplexy 4 months after treatment was restarted.Case presentation A male patient in his 60s with a background of chronic lymphocytic leukaemia(CLL)on ibrutinib and venetoclax presents with acute confusion and deranged electrolytes.He is found to be hyponatraemic and is diagnosed with Syndrome of Inappropriate Antidiuretic Hormone Secretion(SIADH)and treated with fluid restriction.He represents again 3 weeks later with hyponatraemia and further investigations reveal pituitary insufficiency and macroadenoma.He was restarted on ibrutinib and venetoclax at the time of discharge.Four months later,he presents with sudden retro-orbital headache associated with vomiting.Clinical findings include cranial nerve III,IV and XI palsy.Humphrey’s visual field examination revealed a left visual field index(VFI)of only 1%while the right was 64%with temporal hemianopia.Both pupils were mid-dilated and poorly reactive to light.MRI pituitary with contrast showed features of pituitary apoplexy and optic nerve compression.He was urgently referred to the neurosurgical team and underwent an emergency trans-sphenoidal hypophysectomy with circumferential excision of the macroadenoma.Post-operative recovery was uneventful with marked improvement in vision bilaterally.The patient was restarted on ibrutinib and venetoclax 2 weeks post-operatively.Approximately 1 year post-treatment,he remains in radiological,clinical and biochemical remission from CLL and all medications have been withdrawn.Conclusions This is a unique and rare case of pituitary macroadenoma apoplexy following the commencement of ibrutinib for CLL.Central nervous system haemorrhage is a rare side effect of ibrutinib due to its platelet dysfunction effects.A thorough assessment is required to assess the risks and benefits of using ibrutinib in patients with pituitary macroadenoma to avoid serious complications.
文摘This study is aimed to classify degrees of diaphragma sellae (DS) descent into sella turcica according to the surgical field block caused by the descent and to construct predictive imaging criteria for the degree of descent,and in addition,to determine whether there is any correlation between the degree of DS descent and the operative outcome (in the form of cerebrospinal fluid leak and/or presence of residual tumor).Totally,72 patients were enrolled in our study.Their clinical and radiological data as well as the high definition videos of operations were retrospectively reviewed.The degree of DS descent during the operation was classified into five degrees according to surgical field block caused by the descent.We investigated the correlation between these five degrees and the clinical findings,radiological findings as well as the surgical outcomes.We found that the most important determining factors of DS descent degree were the volume and the height of the tumor portion above diaphragma opening.On the other hand,the total tumor volume,the maximum tumor height and the morphological pattern according to Wilson's system (modified from Hardy) had no statistically significant correlation with DS degree of descent.Presence of residual tumor on postoperative magnetic resonance images was significantly correlated with Wilson's classification and with supradiaphragmatic tumor height.On the other hand,cerebrospinal fluid leak showed no statistically significant difference between variable degrees of DS descent.Volumetric data of the tumor portion above the diaphragma opening are more important than morphological data for prediction of surgical field block caused by descended DS.While DS prolapse significantly increases the difficulty of the operative procedure,residual tumor presence is mainly dependent on morphological classification,especially cavernous sinus invasion.
