Mucoceles of the paranasal sinuses cause progressive distension of the bony walls and induce compressive symptoms. Although rare, cases of massive intracranial extension have occurred. We believe that an endoscopic transnasal approach is the best choice for such huge mucoceles because it is the least invasive and can provide an adequate surgical field of view for wide marsupialization. However, the results of long-term follow-up after endoscopic transnasal surgery have not been reported. This study was designed to evaluate prospectively the postoperative course of patients with intracranially extended mucocele. In the last 5 years, we have operated on four patients with intracranially extended mucocele. Although postoperative scanning is not recommended routinely after surgery for inflammatory disease, we followed up two patients who consented by using magnetic resonance imaging (MRI) along with endoscopy. Dural descent to the original skull base plane necessitated long periods of follow-up, lasting 18 and 5 months, respectively. On the mucocele wall mucosa, which had been smooth during surgery, polyps and granulations developed after surgical drainage and lasted for a considerable time. Although endoscopic transnasal opening of mucocele is a method of choice, we recommend follow-up of such patients for long periods, at least until the frontal skull base dura returns to its original position.

Objective To determine the rate of therapeutic hypothermia (TH) use, current practices, and long-term follow-up. Study Design Prospective cross-sectional national survey with 19 questions related to the assessment of hypoxic–ischemic encephalopathy (HIE) and TH practices. An online questionnaire was made available to health care professionals working in neonatal care in Brazil. Results A total of 1,092 professionals replied, of which 681 (62%) reported using TH in their units. Of these, 624 (92%) provided TH practices details: 136 (20%) did not use any neurologic score or amplitude-integrated electroencephalogram (aEEG) to assess encephalopathy and 81(13%) did not answer this question. Any specific training for encephalopathy assessment was provided to only 81/407 (19%) professionals. Infants with mild HIE are cooled according to 184 (29%) of the respondents. Significant variations in practice were noticed concerning time of initiation and cooling methods, site of temperature measurements and monitoring, and access to aEEG, electroencephalogram (EEG), and neurology consultation. Only 19% could perform a brain magnetic resonance imaging (MRI), and 31% reported having a well-established follow-up program for these infants. Conclusion TH has been implemented in Brazil but with significant heterogeneity for most aspects of hypothermia practices, which may affect safety or efficacy of the therapy. A step forward toward quality improvement is important.

Unusual Appearance

A case of extramedullary plasmacytoma with its unusual appearance is reported. This is the second reported case in world literature affecting the paranasal sinuses with intracranial extension. The role of surgery is to obtain tissue for diagnosis and to excise residual disease. Radiotherapy is the treatment of choice and long-term follow-up is necessary for monitoring disease recurrence. The overall 10-year survival is about 50%. The case is discussed with a general review of the management of this pathology.

Abstract Fibrous dysplasia is a rare condition. We present a case of a 34-years-old man presented with left-sided facial pain, headache and nasal obstruction for a long duration. CT scan of the sinuses showed a mass occupying the left ethmoidal region abutting the orbit and skull base obstructing the left frontal sinus. The patient was treated successfully by image-guided endoscopic endonasal removal of the tumor with no recurrence after 3 years of follow-up. This report aims to show the usefulness of endoscopic endonasal removal of a large fibrous dysplasia of paranasal sinuses and skull base.

Pineal parenchymal tumors are rare. Of the three types of pineal parenchymal tumors, pineocytomas are the least aggressive and are not known to diffusely disseminate. In this paper, we report the successful treatment of a case of pineocytoma with diffuse leptomeningeal relapse following initial stereotactic radiotherapy. A 39-year-old female presented with headaches, balance impairment, urinary incontinence, and blunted affect. A pineal mass was discovered on magnetic resonance imaging (MRI). A diagnosis of pineocytoma was established with an endoscopic pineal gland biopsy, and the patient received stereotactic radiotherapy. Ten years later, she developed diffuse leptomeningeal dissemination. The patient was then successfully treated with craniospinal radiation therapy. Leptomeningeal spread may develop as late as 10 years after initial presentation of pineocytoma. Our case demonstrates the importance of long-term follow-up of patients with pineal parenchymal tumors following radiation therapy, and the efficacy of craniospinal radiation in the treatment of leptomeningeal dissemination.

Abstract BACKGROUND: Epilepsy surgery involving the cingulate gyrus has been mostly presented as case reports, and larger series with long-term follow-up are not published yet. OBJECTIVE: To report our experience with focal epilepsy arising from the cingulate gyrus and surrounding structures and its surgical treatment. METHODS: Twenty-two patients (mean age, 36; range, 12–63) with a mean seizure history of 23 years (range, 2–52) were retrospectively analyzed. We report presurgical diagnostics, surgical strategy, and postoperative follow-up concerning functional morbidity and seizures (mean follow-up, 86 months; range, 25–174). RESULTS: Nineteen patients showed potential epileptogenic lesions on preoperative magnetic resonance imaging (MRI). All patients had noninvasive presurgical workup; 15 (68%) underwent invasive Video-electroencephalogram (EEG)-Monitoring. In 12 patients we performed extended lesionectomy according to MRI; an extension with regard to EEG results was done in 6 patients. In 4 patients, the resection was incomplete because of the involvement of eloquent areas according to functional mapping results. Eight pure cingulate resections (36%, 3 in the posterior cingulate gyrus) and 14 extended supracingular frontal resections were performed. Nine patients experienced temporary postoperative supplementary motor area syndrome after resection in the superior frontal gyrus. Two patients retained a persistent mild hand or leg paresis, respectively. Postoperatively, 62% of patients were seizure-free (International League Against Epilepsy [ILAE] 1), and 76% had a satisfactory seizure outcome (ILAE 1–3). CONCLUSION: Epilepsy surgery for lesions involving the cingulate gyrus represents a small fraction of all epilepsy surgery cases, with good seizure outcome and low rates of postoperative permanent deficits. In case of extended supracingular resection, supplementary motor area syndrome should be considered.

The Mean

Hemangiopericytomas are rare tumors of vascular origin most commonly found in the extremities or retroperitoneal area. When they originate from the nasal cavity and paranasal sinuses, they tend to be less aggressive and generally do not metastasize. The term “hemangiopericytoma-like lesion” has been coined for sinonasal hemangiopericytomas that display more benign histologic and growth characteristics than do those located elsewhere. Fifteen cases of hemangiopericytoma of the nasal cavity and paranasal sinuses were reviewed over the period 1951 to 1990; included are follow-up data on cases reported earlier from this institution. The clinical course, management, and outcome was evaluated and correlated with the histologic characteristics of the tumors. The recurrence rate in our series was 13.3%; the mean follow-up was 11 years. No patients died of their disease or had evidence of metastatic disease. This clinicopathologic review suggests that sinonasal hemangiopericytomas should not be classified as “hemangiopericytoma-like” lesions; rather, they should be expected to have significant local recurrence rates with low rates of distant metastasis and mortality. Long-term follow-up is essential as there can be local recurrence after many years.

The One

Ancient Egyptians were pioneers in many fields, including medicine and surgery. Our modern knowledge of anatomy, pathology, and surgical techniques stems from discoveries and observations made by Egyptian physicians and embalmers. In the realm of neurosurgery, ancient Egyptians were the first to elucidate cerebral and cranial anatomy, the first to describe evidence for the role of the spinal cord in the transmission of information from the brain to the extremities, and the first to invent surgical techniques such as trepanning and stitching. In addition, the transnasal approach to skull base and intracranial structures was first devised by Egyptian embalmers to excerebrate the cranial vault during mummification. In this historical vignette, the authors examine paleoradiological and other evidence from ancient Egyptian skulls and mummies of all periods, from the Old Kingdom to Greco-Roman Egypt, to shed light on the development of transnasal surgery in this ancient civilization. The authors confirm earlier observations concerning the laterality of this technique, suggesting that ancient Egyptian excerebration techniques penetrated the skull base mostly on the left side. They also suggest that the original technique used to access the skull base in ancient Egypt was a transethmoidal one, which later evolved to follow a transsphenoidal route similar to the one used today to gain access to pituitary lesions.
