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.

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.

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.

The multiseptate bladder is a congenital bladder anomaly that is very rare and often accompanied by other congenital abnormalities. This condition could result in intravesical obstruction and kidney failure in more serious conditions. A 3-year-old girl without any complaint was consulted by the Pediatric Surgery Department with postoperative cloacal type malformation anorectal (MAR) postero-sagittal anorecto-vagino-urethroplasty (PSARVUP) + sigmoidectomy. Magnetic Resonance Imaging (MRI) of the pelvis showed the appearance of four interconnected multiple fluid lesions. Cystoscopy was performed and found many septa with varied positions and forms. From the cystography during the operation, it was seen duplication of the right and left bladder. There was no further operative treatment in the field of urology because no urinary tract obstruction and normal renal function were found in this study.

Abstract Background Meningiomas typically manifest on magnetic resonance imaging (MRI) as iso- to hypointense on T1-weighted imaging and iso- to hyperintense on T2-weighted imaging. After contrast administration, they usually homogeneously enhance and exhibit a visible dural tail. Meningiomas with atypical findings may be misdiagnosed. Case presentation We report a 50-year-old female patient with a pathologically diagnosed fibrous meningioma (World Health Organization grade I) that exhibited ring enhancement on MRI. Conclusions Meningiomas may rarely present with ring enhancement on MRI. The natural history and mechanisms of cystic degeneration and enhancement in the various types of meningioma require further study.

We present a very rare case of malignant chondroid syringoma of the fingertip in a 44-year-old man that was reconstruced by neurovascular island flap after the complete tumor resection of the fingertip. Although it is a rare tumor at an unusual area, it should be included in the differential diagnosis of the finger tumors.

Utero-ovarian ligament fibroids are among the rarest sites for extrauterine leiomyomas. Broad ligament fibroids are relatively common. They can be either asymptomatic or present with chronic pelvic pain and pressure symptoms. They can be confused with an ovarian mass, broad ligament cyst or a pedunculated fibroid. There are high chances of missing it clinically. Ultrasonography, magnetic resonance imaging (MRI) and computed tomography scan are the imaging techniques used to diagnose such conditions, MRI being the most accurate in ruling out other broad ligament masses with suspected ovarian, tubal or isolated broad ligament cyst. Here is a rare case report of a pedunculated extrauterine leiomyoma with its origin in the utero-ovarian ligament.

Hematomas caused by surgery or trauma that persist and expand slowly for more than a month are defined as chronic expanding hematomas (CEH). Magnetic resonance imaging (MRI) is useful for the diagnosis. Total excision with the pseudocapsule is the treatment method. Pseudoaneurysms result from arterial wall disruptions and can be mistaken for CEH. We present a rare case report of a 45-year-old man with a large, painful swelling in his left popliteal fossa. He had a puncture wound by a nail 11 years ago and a gradually expanding mass occurred in his popliteal fossa. A pseudoaneurysm was detected and operated a year later. After surgery, a gradually expanding mass recurred in his popliteal fossa. On the arteriography, the popliteal artery was occluded and the blood flow was maintained with collateral vessels. On MRI, an enormous swelling of 115 × 107 × 196 cm in diameter was seen. It was diagnosed as CEH and was excised completely protecting the collateral vessels and there was no recurrence after a year from the surgery.

: 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.

Abstract Background Management of postoperative chylothorax usually consists of nutritional regimens, pharmacological therapies such as octreotide, and surgical therapies such as ligation of thoracic duct, but a clear consensus is yet to be reached. Further, the variation of the thoracic duct makes chylothorax difficult to treat. This report describes a rare case of chylothorax with an aberrant thoracic duct that was successfully treated using focal pleurodesis through interventional radiology (IVR). Case presentation The patient was a 52-year-old man with chylothorax after a thoracoscopic oesophagectomy for oesophageal cancer. With conventional therapy, such as thoracostomy tube, octreotide or fibrogammin, a decrease in the amount of chyle was not achieved. Therefore, we performed lymphangiography and pleurodesis through IVR. The patient appeared to have an aberrant thoracic duct, as revealed by magnetic resonance imaging (MRI); however, after focal pleurodesis, the leak of chyle was diminished, and the patient was discharged 66 days after admission. Conclusions Chylothorax remains a difficult complication. Focal pleurodesis through IVR can be one of the options to treat chylothorax.
