A Rare Case of a Congenital Nasopharyngeal Ganglioglioma With Dyspnea in a 1-Month-Old Male Infant: A Case Report

Background: A ganglioglioma (GG), a tumor with both neuronal and astrocytic components, rarely occurs outside the central nervous system.Case Summary: We present the first reported case of a 1-month-old male with a congenital nasopharyngeal GG, nasal congestion, and dyspnea; we include the operative video. Magnetic resonance imaging was used to explore whether the tumor communicated with the intracranial space. We used an endoscopic plasma technique to ensure complete tumor resection. This afforded a good visual field, endoscopic magnification, and good hemostasis.Conclusions: We report a rare case of a nasopharyngeal GG triggering nasal congestion and dyspnea in a 1-month-old male, and report our experience with the treatment of nasopharyngeal GG and similar diseases.

Gnathic Osteosarcoma (GOS) is a subtype of osteosarcoma (OS) that primarily affects the maxilla and mandible. An accurate diagnosis, usually facilitated by Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and Biopsy, is required to define the stage of the disease and plan adequate treatment. Early diagnosis and complete tumor resection are mandatory to improve the prognosis of GOS. We present a case of GOS in a 17-years-old female based on clinical-radio-pathological correlation.

Abstract Objective: The aim of this study was to demonstrate the usefulness of a mobile, intraoperative 0.15-T magnetic resonance imaging (MRI) scanner in glioma surgery. Methods: We analyzed our prospectively collected database of patients with glial tumors who underwent tumor resection with the use of an intraoperative ultra low-field MRI scanner (PoleStar N-20; Odin Medical Technologies, Yokneam, Israel/Medtronic, Louisville, CO). Sixty-three patients with World Health Organization Grade II to IV tumors were included in the study. All patients were subjected to postoperative 1.5-T imaging to confirm the extent of resection. Results: Intraoperative image quality was sufficient for navigation and resection control in both high-and low-grade tumors. Primarily enhancing tumors were best detected on T1-weighted imaging, whereas fluid-attenuated inversion recovery sequences proved best for nonenhancing tumors. Intraoperative resection control led to further tumor resection in 12 (28.6%) of 42 patients with contrast-enhancing tumors and in 10(47.6%) of 21 patients with noncontrast-enhancing tumors. In contrast-enhancing tumors, further resection led to an increased rate of complete tumor resection (71.2 versus 52.4%), and the surgical goal of gross total removal or subtotal resection was achieved in all cases (100.0%). In patients with noncontrast-enhancing tumors, the surgical goal was achieved in 19 (90.5%) of 21 cases, as intraoperative MRI findings were inconsistent with postoperative high-field imaging in 2 cases. Conclusion: The use of the PoleStar N-20 intraoperative ultra low-field MRI scanner helps to evaluate the extent of resection in glioma surgery. Further tumor resection after intraoperative scanning leads to an increased rate of complete tumor resection, especially in patients with contrast-enhancing tumors. However, in noncontrast-enhancing tumors, the intraoperative visualization of a complete resection seems less specific, when compared with postoperative 1.5-T MRI.

: Osteosarcoma of the jaws (OSJ) is a relatively rare disease, accounting for between 2% and 10% of all cases of osteosarcoma, it is morphologically and radiologically identical to the trunk and extremity variant, but distinct in several crucial aspects. : The lesion is characterized by sarcomatous cells which produces a variable amount of osteoid bone. It arises centrally within the bone and can be subdivided into osteoblastic, chondroblastic and fibroblastic subtype, depending on the predominant cell type. : Radiographically, these tumors display a spectrum of bone changes from well-demarcated borders to lytic bone destruction with indefinite margins and variable cortical bone erosion or, in some cases, images of sclerotic bone. Therapeutic options for OSJ include surgery, chemotherapy and radiotherapy, which are employed according to age of the patient, histological classification and localization of the tumor. Today there is no a general consensus in the treatment guidelines for the OSJ though surgery represents the key of the treatment. The main prognostic factor deeply influencing the patient's prognosis remains the complete tumor resection with negative surgical margins. : The aim of the present review is to describe the state of the art regarding diagnostic and surgical treatment aspects of the primary osteosarcoma of the jaws.

We report the rare case of 65-year-old male patient with supratentorial hemangioblastoma and gigantic cyst of the left hemisphere of the brain without von Hippel-Lindau disease. Hemangioblastoma is a rare benign tumor classified as grade I by the WHO of the central nervous system of uncertain histogenesis. This neoplasm’s stroma consists of dense networks of thin-walled blood vessels of various calibers. About 140 cases of supratentorial localization of this type of tumor are presented in the world literature. We have given a fairly complete clinical, neuroradiological and histological picture that allows one to differentiate hemangioblastoma from other histological structures. Promising modalities in the treatment of patients with this pathology when it is impossible to perform total tumor resection are considered.

Cardiac leiomyosarcoma is an extremely rare tumor with a poor prognosis. An 18-year-old female patient was admitted to our clinic with a left atrial leiomyosarcoma extending to the right lower pulmonary veins. We performed complete tumor excision by the right anterolateral mini-thoracotomy approach using minimally invasive techniques. After pathological confirmation of the tumor, right lower lobectomy was performed with the same incision one week later to prevent recurrence. Although no tumor remnant was found in the lobectomy specimen, adjuvant chemotherapy was started. No recurrence was detected during the 12-month follow-up. In conclusion, the right submammarian minithoracotomy approach has the advantages of its less invasive nature and suitability for complete tumor resection with lobectomy.

ObjectiveComplete tumor resection is considered essential in the management of patients with ovarian clear-cell carcinoma. There is a debate regarding whether patients with recurrent ovarian clear-cell carcinoma benefit from secondary cytoreductive surgery.MethodsDetails of patients with clear-cell carcinoma were collected by the Tokai Ovarian Tumor Study Group (Nagoya University Hospital and 13 affiliated institutions) and evaluated between January 1990 and December 2015. Histology was confirmed after central pathological review. The primary endpoint of the study was disease-free survival after secondary cytoreductive surgery. Distributions of events were evaluated using the χ2 test. Survival analysis was based on the Kaplan-Meier method. Survival curves were compared using the log-rank test. A value of p<0.05 was considered significant.ResultsA total of 169 patients who underwent secondary cytoreductive surgery (N=25) or medical management (N=144) for recurrent clear-cell carcinoma were collected. The median age for patients undergoing secondary cytoreductive surgery was 50 years (range 35–66). Overall, 18 patients had complete resection. In patients who underwent secondary cytoreductive surgery, the median disease-free and post-recurrence survival periods were 10.9 months and 21.2 months, respectively. Moreover, among 18 patients who underwent complete resection, seven showed no evidence of disease during the observation periods. The median post-recurrence survival periods of patients with complete or incomplete resection were 30.1 months and 10.4 months, respectively (p=0.002). On stratification by the recurrence site, patients with intraperitoneal recurrence showed poorer post-recurrence survival than those with recurrence at other sites (p=0.016). However, comparison between the secondary cytoreductive surgery group versus the medical management group showed there was no difference in post-recurrence survival, even when considering complete tumor resection (p=0.114).ConclusionPatients with intraperitoneal recurrence or incomplete tumor resection had the worst survival after secondary cytoreductive surgery.

We present the case of a 30-year-old male patient with an almost complete destruction of the calvarial bone through an anaplastic meningioma diagnosed in line with dizziness. Neuroimaging revealed an extensive growing, contrast enhancing lesion expanding at the supra- and infratentorial convexity, infiltrating and destroying large parts of the skull, and infiltrating the skin. Due to progressive ataxia and dysarthria with proven tumor growth in the posterior fossa in the continuing course, parts of the tumor were resected. A surgical procedure with the aim of complete tumor resection in a curative manner was not possible. Six months after the first operation, due to a new tumor progression, most extensive tumor resection was performed. Due to the aggressive and destructive growth with a high rate of recurrence and tendency of metastases, anaplastic meningiomas can be termed as malignant tumors. The extrinsic growth masks the tumor until they reach a size, which makes these tumors almost unresectable. In the best case scenarios, the five-year survival is about 50%. With the presented case, we would like to show the aggressive behavior of anaplastic meningiomas in a very illustrative way. Chemotherapy, radiotherapy, and surgery reach their limits in this tumor entity.
