Primary aspergillosis of the sphenoid sinus with pituitary invasion – a rare differential diagnosis of sellar lesions

Summary Aspergillosis belongs to the group of mycotic diseases of paranasal sinuses. The invasive forms, and particularly the fulminant forms, are potentially fatal. Isolated aspergillosis of the sphenoid sinus or the clivus is a difficult diagnosis, since the often misleading clinical manifestations of this rare disease develop late. These patients become apparent by neurological signs such as cavernous sinus syndrome, pseudotumor of the pituitary or the orbit. Diagnosis is often made intra-operatively or on histological examination. We report a case of invasive aspergillosis uniquely involving the sellar area revealed by clinical features suggesting a pseudotumor of the pituitary. Although such lesions are almost always seen in immune suppressed subjects, in our case, the patient was immune competent and had no past history of sinusitis. The question of whether, and when to perform limited or extensive surgery remains an issue for discussion, owing to the rarity of this disease honed by lack of experience. It depends on several factors: the kind of disease, the immunity, the subtype of invasive fungal sinusitis and the degree of tissue invasion.     

小骨窗术和碎吸术治疗脑出血的临床应用研究

目的对比研究颅内血肿小骨窗清除术和颅内血肿(钻孔)碎吸清除术治疗脑出血的疗效。方法87例脑出血患者分为小骨窗组(行颅内血肿小骨窗清除术)、碎吸组(行颅内血肿碎吸清除术)和对照组(行内科保守治疗)。分别比较小骨窗组、碎吸组、保守组治疗前后的GCS评分及3组的GCS评分差。采用t检验、χ2检验和单因素方差分析比较。结果小骨窗组、碎吸组与保守组的GCS评分差比较均有差异(P<0.05);小骨窗组和碎吸组的GCS评分差比较也有差异(P<0.05)。结论小骨窗颅内血肿清除术、碎吸颅内血肿清除术、内科保守疗法在脑出血治疗中均能发挥一定的作用。小骨窗术和碎吸术在治疗中均能提高疗效、加快神经功能恢复,但小骨窗术较碎吸术能更好地发挥疗效、提高病人的生存质量。

Does Meningitis Stop CSF Rhinorrhea following Lateral Skull Base Surgery?

In cases of cerebrospinal fluid (CSF) rhinorrhea following lateral skull base surgery, fibrosis and fibrin formation resulting from meningitis has been postulated as a mechanism of spontaneously resolving the CSF leak. This study was undertaken to explore any possible relationship between the cessation of CSF leak and meningitis. A retrospective study at a tertiary referral center of 232 consecutive patients was performed. Out of a total of 232 procedures, 29 patients developed CSF rhinorrhea, of whom 7 subsequently developed meningitis. Bacteria were isolated in CSF obtained at lumbar puncture in 5 cases, with the CSF analysis in the remaining 2 cases suggesting aseptic meningitis. Conservative treatment failed to stop the CSF rhinorrhea in 6 of 7 cases. In this study, the development of meningitis did not appear to aid in the resolution of the CSF rhinorrhea. We conclude that surgical intervention should not be delayed in the expectation that meningitis and conservative interventions may promote CSF leak resolution.     

改良额颞-颞下窝入路切除中颅凹底内外沟通瘤

目的：为了更完全地切除中颅凹底内外沟通性肿瘤。方法：采用经过改良的Ｍｉｃｋｅｙ额颞颞下窝入路。其改良主要是将额骨瓣连同其表面附着的颞肌以及游离后的眶颧骨块一并向下翻开，并将手术程序作了相应改变。结果：成功切除了１３例肿瘤。术后３例恢复了轻工作，６例能自主生活，３例生活仍需别人照顾，１例复发未再次手术。结论：采用改良的额颞颞下窝入路对中颅凹底内外沟通性肿瘤暴露充分，切除广泛。Ｍｉｃｋｅｙ入路改良的优点：颞肌血运的保留，有利于骨瓣与正常颅骨的早期融合。同时颞肌附着点的保留，有利于咀嚼功能。     

伽玛刀治疗颅底良性脑膜瘤临床研究

目的探讨伽玛刀放射外科治疗良性颅底脑膜瘤中长期疗效和不良反应。方法选取了1998-2003年治疗的获得完全随访资料的颅底脑膜瘤患者166例,全组患者肿瘤体积0.42- 43.4cm3,平均(7.2±3.9)cm3,给予周边剂量平均(12.4±2.6)Gy,中心剂量平均(27.9±5.9)Gy,其中12例患者采用肿瘤体积分割二阶段治疗。对治疗前后的影像学改变、KPS评分和神经功能缺损评估。结果平均随访期为(55.4±18.2)个月(36-96个月)。总体控制率为95.2%(158/166);KPS评分得到显著提高,神经症状总体满意率为94.5%(157/166),主要副作用是放射性脑水肿11例(6.6%),有5例(3%)患者出现新的神经缺损。结论伽玛刀放射外科可以作为有手术禁忌或拒绝手术治疗体积较小脑膜瘤患者的首选性治疗,也可以作为颅底较大脑膜瘤开颅术后的辅助性治疗,能够较长期控制肿瘤复发,提高或保持患者的生存质量。     

Closure of a large bronchial fistula with a latissimus dorsi myocutaneous flap

We describe a case of a large bronchial fistula and empyema after right upper lobectomy that was treated successfully with open window thoracostomy followed by a latissimus dorsi myocutaneous flap and limited thoracoplasty. A latissimus dorsi myocutaneous flap can provide immediate airtight closure of a large bronchial fistula, allowing lavage and curettage of the empyema cavity to reduce the chance of postoperative infection. An important aspect of this technique is that the deepithelialized skin side rather than muscle is sutured to an opening of the bronchus. As compared with other techniques, a latissimus dorsi myocutaneous flap is superior in that it requires a single incision and does not require an intraop-erative change of position. In addition, the technique causes little dysfunction of the chest and shoulder and preserves the vascular supply to ensure the viability of the flap even if it was divided in a previous operation.     

Glomus jugulare tumours: A review of 61 cases

Summary A retrospective study of 61 patients with glomus jugulare tumours treated at the National Hospital for Neurology and Neurosurgery, and at the Royal National Throat, Nose and Ear Hospital, London. The average age at presentation was 41.7 years. The patients were mainly treated by a posterolateral combined otoneurosurgical approach. 42/61 of the patients had total or subtotal excision of their tumours, 7/61 had partial removal and the remaining 11/61 had no operation. Only one case required a 2-staged procedure. There were two deaths in the postoperative period, one from intracerebral haemorrhage and the other from the left hemisphere infarction.Postoperative radiotherapy was given to 5/7 of the patients who had partial removal. 3/40 of the patients with total removal had postoperative radiotherapy, and a further 3/40 had received radiotherapy pre-operatively.Of the 11 patients who did not undergo surgery, 7/11 were treated with radiotherapy and 4/11 had embolisation only.
