Background Intracranial chondromas are extremely rare and represent only 0.2% of all intracranial primary neoplasms. The histologic appearance lacks nuclear atypism and mitoses, and it usually shows low growth potential, although these benign features do not necessarily imply a good prognosis. Case Description A 44-year-old man was referred to our institution with a subarachnoid hemorrhage (SAH). He had a history of SAH 5 years previously that was diagnosed as unknown etiology at another hospital. Head magnetic resonance imaging showed a large tumor located in the prepontine cistern and extending up to the interpeduncular cistern, and the tumor was irregularly enhanced with contrast medium. Retrospective analysis of the original computed tomography of 5 years earlier identified a small contrast enhancing defect behind the dorsum sellae. Tumor removal was planned to prevent repeated SAH and control the apparently growing tumor. An extended transsphenoidal approach was performed. The pituitary gland was dissected from the bottom of the sellar floor and transposed forward to the prechiasmatic cistern with preservation of the pituitary stalk and its blood supply, and subtotal removal of the tumor was achieved. Postoperative diabetes insipidus disappeared within a few days, and the patient was discharged without neurologic or endocrinologic deficits. Histologic examination established the diagnosis as chondroma without a sarcomatous component. Follow-up examination 3 months after surgery showed a re-enlargement of the residual tumor, and gamma knife surgery was performed. Conclusions Intracranial chondroma sometimes manifests as intracranial hemorrhage and grows comparatively rapidly in a short period despite the benign histologic features. A long and careful follow-up period is essential.

Spontaneous Subarachnoid Hemorrhage

OBJECT Hemorrhagic origin is unidentifiable in 10%–20% of patients presenting with spontaneous subarachnoid hemorrhage (SAH). While the patients in such cases do well clinically, there is a lack of long-term angiographic followup. The authors of the present study evaluated the long-term clinical and angiographic follow-up of a patient cohort with SAH of unknown origin that had been enrolled in the Barrow Ruptured Aneurysm Trial (BRAT). METHODS The BRAT database was searched for patients with SAH of unknown origin despite having undergone two or more angiographic studies as well as MRI of the brain and cervical spine. Follow-up was available at 6 months and 1 and 3 years after treatment. Analysis included demographic details, clinical outcome (Glasgow Outcome Scale, modified Rankin Scale [mRS]), and repeat vascular imaging. RESULTS Subarachnoid hemorrhage of unknown etiology was identified in 57 (11.9%) of the 472 patients enrolled in the BRAT study between March 2003 and January 2007. The mean age for this group was 51 years, and 40 members (70%) of the group were female. Sixteen of 56 patients (28.6%) required placement of an external ventricular drain for hydrocephalus, and 4 of these subsequently required a ventriculoperitoneal shunt. Delayed cerebral ischemia occurred in 4 patients (7%), leading to stroke in one of them. There were no rebleeding events. Eleven patients were lost to followup, and one patient died of unrelated causes. At the 3-year follow-up, 4 (9.1%) of 44 patients had a poor outcome (mRS > 2), and neurovascular imaging, which was available in 33 patients, was negative. CONCLUSIONS Hydrocephalus and delayed cerebral ischemia, while infrequent, do occur in SAH of unknown origin. Long-term neurological outcomes are generally good. A thorough evaluation to rule out an etiology of hemorrhage is necessary; however, imaging beyond 6 weeks from ictus has little utility, and rebleeding is unexpected.

Prognostic Group

e15585 Background: According to IGCCCG, pts with MNGCT belong to poor prognostic group. But, there are no independent prognostic factors which could determine prognosis in this group of pts. We retrospectively studied prognostic factors in pts with MNGCT. Methods: We analyzed data on 61 pts with MNGCT, who were treated in our department during 1986-2011. Median age was 23 years (range: 18-44). Median follow-up time was 52 months (range 4-180). Biopsy was performed in 35/61 (57.4%) pts before treatment. At the beginning of therapy median AFP was 3,360 IU/ml (range: 1-300,000), HCG – 4.5 mIU/ml (range: 0.1 to 326210), LDH – 791 U/l (range: 249-4,475). Conventional induction chemotherapy (CT): classical BEP regimen – 23 (37.8%) pts, T-BEP – 17 (27.8%) pts, CPOB – 17 (27.8%) pts, accelerated (two-weekly) BEP – 4 (6.6%) pts. After CT, residual tumor was resected in 28 (45.9%) pts. Multivariate Cox regression analysis was performed to determine independent factors, which influenced on overall survival (OS). Results: Marker-negative objective response was revealed in 40/61 (65.6%). Progression disease during induction CT was detected in 21 (34.4%) pts. 5-years OS was 44% for all pts. Multivariate analysis revealed the following independent negative prognostic factors: age ≥ 24 (р=0.08, HR 1.9, 95%CI 0.92-4.1), size of the primary mediastinal tumor ≥ 19 cm (р= 0.03, HR 5.8, 96%CI 1.85-18.67). Median OS hasn’t been reached and 3-year OS was 62% in pts with good prognosis (age < 24 years and/or size of mediastinal tumor < 19 cm) vs. 15 months and 30% in pts with poor prognosis (р=0.02, HR 0.42, 95%CI 0.19-0.87) respectively. Conclusions: Age ≥ 24 and size of the primary mediastinal tumor ≥ 19 cm are independent negative prognostic factors in pts with MNGCT. These factors could be used as strata in clinical trials. However, this tendency has to be confirmed in large series of pts.

✓ The mortality rate, risk of rebleeding, relevant subjective and objective symptoms, and daily functional capacity after a verified subarachnoid hemorrhage (SAH) of unknown etiology were evaluated in 44 patients treated during a 5-year period (1978 to 1983). A vascular basis for the SAH had been excluded by bilateral carotid and vertebral angiography and computerized tomography. The patients were interviewed at a follow-up examination from 3 to 64 months (median 36 months) after the bleed. The results revealed a 5% mortality rate and a 7% risk of rebleeding. Persisting headache and fatigue were found in 40% of patients, 29% had mild demential symptoms, and 5% had persisting and severe objective neurological symptoms. None had developed epilepsy. A normal daily functional capacity was enjoyed by 84%, while 14% had a moderate reduction in these functions, but were independent of help from other persons. One patient (2%) was not fully assessed.

BackgroundVulvar cancer is the fourth most common gynecologic cancer, and prognosis is poor in advanced vulvar cancer patients. Treatment for advanced vulvar cancer has not been satisfactory. In this report, we firstly report a FIGO IVB vulva verrucous carcinoma patient who obtained good prognosis after systemic treatment.Case PresentationA patient was admitted to hospital due to her vulvar lesion persistent for past 14 years. The vulvar mass has widely invaded urethra, part of anus, the lower third of the vagina, bilateral superior and inferior branches of pubis, and bilateral internal and external muscles of obturator. Multiple metastatic lymph nodes were also found in the pelvic cavity. The histopathological studies confirmed vulvar verrucous carcinoma with a PD-L1 overexpression. After six courses of neoadjuvant chemotherapy and pembrolizumab, the patient underwent radical vulvectomy and achieved optimal cytoreduction. Postoperative pathology found no residual tumor. The patient then received one course of postoperative chemotherapy and pembrolizumab, underwent radiation therapy, and was disease free after 6 months follow-up.ConclusionOur individualized treatment strategy is successful. Pembrolizumab is safe and effective in the treatment of advanced vulvar verrucous carcinoma with PD-L1 overexpression.

ABSTRACT Introduction: Orthodontic treatment in patients with traumatized teeth is a condition that needs good planning in order to achieve satisfactory results. Objective: To discuss approaches to orthodontic treatment of malocclusions associated with trauma followed by avulsion of anterior teeth, reimplanted after a short period of time. Case report: The treatment started with the distalization of upper posterior teeth, with the aid of mini-implants and sliding jigs, followed by the inclusion of anterior teeth in the arch, followed by intrusion of these teeth. Results: With the treatment, improved mobility of the anterior teeth was achieved, with better insertion into bone tissue. The most important factor for satisfactory treatment and a good prognosis for avulsion is the time the tooth remains outside the socket. Orthodontic treatment in patients with traumatized teeth is not contraindicated; however, clinical and radiographic aspects must be considered. Conclusion: Among the feasible orthodontic treatment options, the conservative approach can be a very favorable treatment alternative.

Spontaneous Subarachnoid Hemorrhage

Abstract After the institution of computed tomography (CT), 814 cases of spontaneous subarachnoid hemorrhage (SAH) were treated during a period of 6 years and 9 months (April 1978 through December 1984). In 9 (22.0%) of 41 patients whose cause of SAH was not determined by the first four-vessel study (cerebral panangiography), ruptured aneurysms were found by repeated four-vessel study. Thus, of 814 cases, only 32 (3.9%) were diagnosed as cases of unknown etiology at discharge. The 32 cases were monitored by follow-up examination for 5 to 67 months (median, 27.1 months) after onset. No recurrence of SAH was reported, and all patients were rehabilitated except 2 who suffered terminal carcinoma. A third follow-up four-vessel study was performed 8 to 44 months (median, 22.0 months) after the second study in 14 of the 16 patients with SAH initially demonstrated by CT. In 1 of these cases, an aneurysm found 9 months after the initial SAH was treated surgically. Ultimately, 31 cases (3.8%) were diagnosed as cases of SAH of unknown cause. This incidence is low when compared with those in previous reports. Because of the strict examination schedule including repeated angiography, the incidence is lower and the prognosis is relatively favorable.

There have been a few case reports of head injury leading to brain tumour development in the same region as the brain injury. Here we report a case where the patient suffered a severe head injury with contusion. He recovered clinically with conservative management. Follow up Computed Tomography scan of the brain a month later showed complete resolution of the lesion. He subsequently developed malignant brain tumour in the same region as the original contusion within a very short period of 15 months. Head injury patients need close follow up especially when severe. The link between severity of head injury and malignant brain tumour development needs further evaluation. Role of anti-inflammatory agents for prevention of post traumatic brain tumours needs further exploration.

Background: Stent-assisted coiling is an effective method of treating intracranial aneurysms. The aim of the study was to assess the safety and efficacy of the new Accero stent for the treatment of intracranial aneurysms. Materials and Methods: It was a retrospective, single-center study. Eighteen unruptured intracranial aneurysms were treated using the stent-assisted coiling method with the Accero stent. Patient demographics, aneurysm characteristics, procedural parameters, grade of occlusion, complications, and clinical results were analyzed. Follow-up magnetic resonance (MR) was performed 6 months after intervention. Results: Seventeen patients with 18 incidental unruptured aneurysms were electively treated with coiling and the Accero stent. The aneurysms were located on internal carotid artery (ICA), middle cerebral artery (MCA) and basilar artery (BA). All stents were deployed successfully. Immediate complete occlusion rate Raymond-Roy occlusion classification (RROC) class I was achieved in 13 cases and class II in 4 cases. Complications occurred in 2/17 treatments and included guidewire stent perforation with subarachnoid hemorrhage (SAH) and stent deformation. Vascular spasm in the subarachnoid hemorrhage (SAH) patient subsided before discharge. Ninety days after intervention, the modified Rankin Scale (mRS) value was 0. RROC class I was observed in 88.23% of cases in follow-up. Conclusion: The Accero stent provides excellent support for coil mass. It constitutes an efficacious device with good initial occlusion rate for treating wide-necked unruptured intracranial aneurysms.
