OBJECTIVE: Extra-axial lymphoma involving the trigeminal nerve, an uncommon condition that presents as a trigeminal schwannoma, resulted in misdiagnosis and a flawed surgical strategy. We report two cases: a primary lymphoma of Meckel's cave and a metastasis lymphoma in the prepontine cistern arising from the supraclavicular lymph node. CASES REPORT: The first patient presented with a 3-month history of persistent, sharp facial pain across the area innervated by the V2 nerve...

Meckel's diverticulum represents a remnant of the proximal end of the omphalomesenteric duct, which constitutes a connection between the middle intestine and the vitelline vesicle. It is the most common congenital anomaly of the gastrointestinal tract and is found in approximately 0.3-2% of the general population. Complications such as hemorrhage, bowel obstruction, inflammation, perforation, intussusception, volvulus and malignant transformation develop in only 4-4.8% of all patients, with most cases presenting in childhood, while relative risk decreases during life...

BACKGROUND: Meckel's diverticulum (MD) occurs predominantly in children and adolescents. It is rarely diagnosed in adults. Preoperative diagnosis is difficult due to low sensitivity of the radiological imaging studies. The role of video capsule endoscopy (VCE) in the diagnosis of MD is unknown, and the endoscopic patterns are not defined. We will describe four of our cases of MD evaluated with VCE and make a review of the literature focusing on the endoscopic characteristics. CASE SUMMARY: We present four cases of MD confirmed by surgery...

PURPOSE: A hernia containing Meckel's diverticulum is called a Littre's Hernia. It's a rare entity and its diagnosis is often incidental during routine hernia repair surgery. The objective of this study is the evaluation of the current evidence on Littre's hernias regarding their clinical presentation and optimal treatment approach. METHODS: PubMed and Cochrane bibliographical databases were searched from the beginning of time (last search: August 1st, 2018) for studies reporting on Littre's hernias in adult population...

BACKGROUND Amyand's and Littre's hernias are 2 rare types of inguinal hernias, which constitute less than 1% of all types of hernias. Amyand's hernia is characterized mainly by the presence of a vermiform appendix in an inguinal hernia sac, whereas Littre's hernia includes a protrusion of a Meckel's diverticulum into the hernial sac. CASE REPORT In this article, we report a case of co-existence of Amyand's and Littre's hernia in the same sac of a groin hernia. To the best of our knowledge, this is the first case report of a patient with the appendix and Meckel's diverticulum inside the hernia sac...

BACKGROUND AND PURPOSE: In patients with acute ischemic stroke and large vessel occlusion, the prognosis has improved tremendously since the implementation of endovascular thrombectomy (EVT). The effect of EVT on the incidence of malignant middle cerebral artery infarctions (MMI) has not been studied before. METHODS: ESTIMATE, a multicenter retrospective study, evaluates data of ischemic stroke patients with occlusion in the anterior circulation in the years of 2007-2015 comparing three treatment options (no therapy; IV-TPA; IV-TPA plus EVT or EVT only)...

When operating on difficult skull base lesions, it is essential to be able to handle unexpected intraoperative findings or troubles, while achieving maximal lesion removal and minimal functional deficit. This video demonstrates a case of trochlear nerve repair that was performed during the retrosigmoid suprameatal approach for treatment of a petrotentorial meningioma, extending into the Meckel's cave. The patient is a 47-year-old woman with a right petrotentorial meningioma, extending into the Meckel's cave...

We present a case of a posterior fossa trigeminal schwannoma in a 31-year-old gentleman. Preoperative symptomatology included headaches and dizziness of 6 months in duration. Trigeminal schwannomas isolated to the posterior fossa, not extending into Meckel's Cave, may be adequately resected via a retrosigmoid approach. Thus, a tailored retrosigmoid approach was planned with navigation assistance. A key point to highlight is the difficult identification and preservation of trigeminal nerve fascicles within the tumor mass...

Introduction  Large and even moderate sized, extra-axial cerebellopontine angle (CPA) tumors may fill this restricted space and distort the regional anatomy. It may be difficult to determine even with high resolution magnetic resonance imaging (MRI) if the tumor is dural-based, or what the nerve of origin is if a schwannoma. While clinical history and exam are helpful, they are not unequivocal, particularly since many patients present with a myriad of symptoms, or conversely an incidental finding. We present an atypical appearing, asymptomatic CPA tumor, ultimately identified at surgery to be a trigeminal schwannoma...

The combined transpetrosal approach enables wide exposure around the petroclival region by cutting the tentorium and superior petrosal sinus. We often choose this approach for removal of tumors ventral to the facial and vestibulocochlear nerves, such as petroclival meningioma and epidermoid cyst, because complete removal of the tumor under direct visualization is required to prevent its later recurrence, especially in young patients. Recent reports revealed anatomical variations of the drainage of the superior petrosal sinus, and dural incision considering preservation of the superior petrosal vein was proposed...

Intussusception due to an inverted Meckel's diverticulum in adults is rare. We present a case report of a 28-year-old man with Meckel's diverticulum as a cause of ileo-ileal intussusceptions and lower gastrointestinal bleeding. The patient was admitted to the hospital with incomplete small bowel obstruction, abdominal pain and massive rectal bleeding. Surprisingly, pre-operative abdominal USG revealed inhomogeneous target-like mass in the right lower abdominal quadrant as intussusception with an intraluminal polypoid lesion...

Mammalian Meckel´s cartilage is a temporary structure associated with mandible development. Notably, its elimination is not executed by apoptosis, and autophagy was suggested as the major mechanism. Simultaneous reports point to pro-apoptotic caspases as novel participants in autophagic pathways in general. The aim of this research was to find out whether activation of pro-apoptotic caspases (-2, -3, -6, -7, -8 and -9) was associated with autophagy of the Meckel´s cartilage chondrocytes. Active caspases were examined in serial histological sections of mouse mandible using immunodetection and were correlated with incidence of autophagy based on Beclin-1 expression...

Background: Horner syndrome refers to a set of clinical presentations resulting from disruption of sympathetic innervation to the eye and adnexa. Classically, the clinical triad consists of ipsilateral blepharoptosis, pupillary miosis, and facial anhidrosis. Ocular sympathetic denervation may signify life-threatening causes. Timely investigation and accurate diagnosis are essential in patients with oculosympathetic denervation. Case presentation: A 33-year-old Asian man with a heavy smoking habit presented with a 3-week history of left ptosis and no other complaints...
