Abstract This 15-yr-old girl presented with nasal obstruction and dysphagia of duration 3 mo and 8 to 10 pounds of weight loss. On examination, she had a hoarse voice and left tongue deviation without weakness or myelopathy. Computed tomography (CT) demonstrated an erosive lesion arising from the clivus and left occipital condyle. Magnetic resonance imaging (MRI) demonstrated a T1-isointense, T2-hyperintense, enhancing mass centered at the occipital condyle and extending into the craniovertebral junction (CVJ), causing severe brainstem compression and extending inferiorly to C2 and anteriorly into the retropharyngeal space. The patient underwent transoral biopsy to confirm the diagnosis of chordoma and complete tumor resection via a left extreme lateral transodontoid (ELTO) approach. This approach was chosen because it provides bilateral exposure to the ventral CVJ and retropharyngeal space and allows for complete tumor removal using a single approach, although it requires an experienced surgeon. The ELTO incision should provide adequate exposure for occipitocervical fusion (OCF) after the destabilization of the CVJ. Transposition of the vertebral artery and odontoidectomy are key maneuvers that provide exposure to the ventral CVJ bilaterally. Dural closure is performed primarily and augmented with fat, fibrin glue, and temporary cerebrospinal fluid diversion. Postoperative MRI showed a gross-total resection and decompression of the brainstem at the CVJ. The patient remained in a cervical collar until OCF. Postoperatively, she had left vocal cord paralysis and moderate weakness with left arm abduction at the deltoid. At 2-mo follow-up, she had improved lower cranial neuropathies, tolerated oral intake, and was scheduled to begin proton beam therapy. The patient provided consent for publication.

Chordomas of the cranial base are locally destructive tumors since they are surrounded by significant complex neurovascular structures. Thus, their surgical removal is challenging, recurrence rates are high, and their therapeutic strategies remain controversial.In this video, we present a 47-year-old man with a recent onset of swallowing difficulties, hoarseness, and weight loss for several weeks. In the neurological examination, he had complete paralysis of the 9th, 10th, 11th, and 12th cranial nerves. Magnetic resonance imaging (MRI) showed a heterogeneously enhancing expansile invasive mass lesion centered within the clivus and involving the C1, the occipitocervical junction, the retropharynx, and the hypoglossal canal. The decision was made to proceed with multiple staged surgeries. In the first surgical stage, we performed a mastoidectomy with the infralabyrinthine approach to perform a test clip ligation of the sigmoid sinus and to resect the tumor component that extended into the infralabyrinthine space. In the second stage, we performed a far-lateral transcondylar approach for tumor resection and occipitocervical fusion. In the third stage, we used a transoral approach with endoscopic assistance to complete the excision of the remaining tumor in the retropharyngeal space and anterior aspect of C1 and C2 bodies that were not accessible in the first two stages.The surgeries and postoperative course were uneventful. Postoperative MRI showed a gross total resection of the tumor. Histopathology indicated a chordoma. The patient subsequently received proton radiotherapy and has continued to do well without recurrence at 14 months' follow-up.The link to the video can be found at: https://youtu.be/uP9OSlKg_rE.

Abstract BACKGROUND Tumors at the craniovertebral junction are difficult to remove because of their location and complex anatomic relations. The lateral transcondylar approach is a versatile approach to this area and allows access to a variety of intra- and extradural tumors. The lateral transcondylar approach has been used for a series of chordomas in this location. OBJECTIVE The nuances of this operation and its effectiveness in this group of patients are presented. METHODS There were 29 chordomas (1991–2007) in this region treated by one of the authors (CS) that were retrospectively reviewed. The imaging studies and medical records were evaluated. The location and extent of the tumor were defined, and the postoperative images were studied to determine the degree of resection. RESULTS There were 11 male and 18 female patients; their age range was 7 to 67 years. Headache and neck pain were the predominant presenting symptoms, and hypoglossal nerve palsy was the most common cranial nerve palsy. Twelve patients had previous surgery and 9 had previous radiation. Anterior midline and lateral approaches were used independently or in combination to treat these patients. Dural invasion was found in 27 patients requiring resection of the dura. Surgery was performed in 1 stage in 19 patients, and the tumor resection in the remaining patients was done in 2 stages. The lateral transcondylar approach was used in 19 patients. The occipital condyle was involved in all these patients. Radical tumor resection was achieved in 17 patients. Patients who had complete removal of the occipital condyle required occipitocervical fusion (20 patients) in the immediate postoperative period. CONCLUSION The lateral transcondylar approach is an effective approach to chordomas in this region. Most of the tumors were large and extended into multiple anatomic compartments. The approach allowed resection of all the involved tissues, intra- and extracranial, and afforded excellent neurovascular control.

Background: Occipital condylectomy is often necessary to gain surgical access to various neurological pathologies. As the lateral limit of the craniovertebral junction (CVJ), partial condylectomy can lead to iatrogenic craniocervical instability. What was once considered an inoperable location is now the target of various complex neurosurgical procedures such as tumor resection and aneurysm clipping. Methods: In this study, we will review the anatomical structure of the CVJ and provide the first comprehensive assessment of studies investigating craniovertebral stability following condylectomy with the transcondylar surgical approaches. Furthermore, we discuss future considerations that must be evaluated to optimize the chances of preserving craniocervical stability postcondylectomy. Results: The current findings postulate upward of 75% of the occipital condyle can be resected without significantly affecting mobility of the CVJ. The current findings have only examined overall dimensions and have not established a significant correlation into how the shape of the occipital condyles can affect mobility. Occipitocervical fusion should only be considered after 50% condyle resection. In terms of indicators of anatomical stability, components of range of motion (ROM) such as the neutral zone (NZ) and the elastic zone (EZ) have been discussed as potential measures of craniocervical mobility. These components differ by the sense that the NZ has little ligament tension, whereas the EZ does represent ROM where ligaments experience tension. NZ is a more sensitive indicator of instability when measuring for instability postcondylectomy. Conclusion: Various transcondylar approaches have been developed to access this region including extreme-lateral and far-lateral condylectomy, with hopes of preserving as much of the condyle as possible and maintaining postoperative craniocervical stability.

: 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.

Objectives. Clinical records of 27 patients with extracranial head and neck schwannoma were retrospectively reviewed.Methods. Ultrasonography (US) was performed in all cases. Seven patients underwent CT. Twenty-five patients underwent MRI. Fine needle aspiration cytology (FNAC) was performed for 12 of the 27 patients. Clinical history, surgical data, and postoperative morbidity were analyzed.Results. The images of US showed a well-defined, hypoechoic, primarily homogeneous solid mass. At CT, only one of 7 cases (14%) was able to suggest the diagnosis of schwannoma. At MRI, twenty of 25 cases (80%) suggested the diagnosis of schwannoma. Only three of 12 cases (25%) displayed a specific diagnosis of schwannoma rendered on FNAC. The distribution of 27 nerves of origin was 10 (37%) vagus nerves, 6 (22%) sympathetic trunks, 5 (19%) cervical plexuses, 3 (11%) brachial plexuses, 2 (7%) hypoglossal nerves, and 1 (4%) accessory nerve. Complete tumor resection was performed in 11 patients, and intracapsular enucleation of the tumor was performed in 16 patients. The rate of nerve palsy was 100 (11/11) and 31% (5/16).Conclusions. MRI is sensitive and specific in the diagnosis of schwannoma. Intracapsular enucleation was an effective and feasible method for preserving the neurological functions.

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.

Metastatic tumors to the liver resulting in fulminant hepatic failure are a rare occurrence and have not been previously described in patients with gastrointestinal stromal tumor (GIST). A 70 year-old man was referred to hospital with postprandial discomfort. On examination a 19.5 cm large epithelioid GIST of the stomach was diagnosed. The mass exhibited unfavorable prognostic features: mitotic index 18/50 high-power fields, large primary tumor size and male sex. Complete tumor resection with negative margins was achieved and metastases were not detected. The patient presented six months later with jaundice, asterixis and elevated liver enzymes. Computerized tomography showed multiple liver hypodense lesions representing metastases. Treatment with imatinib mesylate was of no avail and the patient died 3 days later as the result of hepatic failure. Massive liver metastases can, even though rarely, be responsible for fulminant hepatic failure. Clinical and radiological follow-up are crucial in patients with GIST even after surgical resection.

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.

A 56-year-old man was admitted to our hospital for urachal carcinoma with peritoneal dissemination. He received first-line chemotherapy with gemcitabine and cisplatin. After the fifth cycle, a computed tomography (CT) scan revealed abdominal fluid, and his serum tumor marker levels were increased. The patient was started on second-line therapy with FOLFIRI. After 11 cycles, his tumor decreased in size and no new metastatic lesions were detected. The patient underwent complete tumor resection with partial cystectomy and pelvic lymph node dissection. The tumor was removed, along with adhering surrounding organs, including the omentum, peritoneum, abdominal rectus muscle, and vermiform appendix. Although pathological examination confirmed peritoneal dissemination, his tumor markers normalized soon after surgery. The patient has survived 62 months after surgery without any adjuvant therapy and with no evidence of recurrence. To our knowledge, this is the longest duration of survival without recurrence of a patient with urachal carcinoma with peritoneal dissemination who received multimodal therapy.
