An Infratentorial Pure Pleomorphic Xanthoastrocytoma Arising from Middle Cerebellar Peduncle: A Rare Location of an Uncommon Tumor.

Cerebellar Pleomorphic Xanthoastrocytoma with BRAF V600E Mutation.

Histopathology and molecular pathology of pediatric pineal parenchymal tumors

Background: Papillary tumor of the pineal region (PTPR) represents a rare and histologically distinct subgroup of tumors originating in the pineal region. Few pediatric cases have been reported so far in the literature; therefore, clinical data are scarce. Case Description: We describe a case of PTPR in a 9-year-old girl who presented with a 5-month history of excessive appetite and weight gain. The patient underwent neuroimaging procedures and total gross surgical resection with postoperative adjuvant local radiotherapy, which from our experience was the best treatment choice as an attempt to avoid local recurrence. During 78-month follow-up, the patient from our study manifested no disease recurrence. Conclusion: PTPR should be included in the differential diagnosis of pineal region masses.

Papillary tumor of the pineal region in pediatric patient – A case report

Tumors in the pineal region are deep, with complex surrounding anatomy, adjacent to important blood vessels and nerve structures, and surgical resection is difficult and risky. In this paper, we reviewed the literature to understand the epidemiology and clinical manifestations of pineal region tumors in the country and study the clinical indications, related problems, and successful experiences of patients with pineal region tumors treated by the transtentorial-superior approach. The clinical data of 80 patients with pineal region tumors were selected as the retrospective research objects and divided into the control group and the treatment group, with 40 cases in each group, according to the random number table method. The control group was treated using the endoscopic transtentorial approach (Poppen approach), while the treatment group was treated with the endoscopic supratentorial approach (Krause approach). The inflammatory factors, inflammatory stress response, postoperative neurological dysfunction, clinical efficacy, and poor prognosis were observed and compared between the two groups. Tumor resection and recurrence were used to compare the clinical outcomes of tumors in the pineal region. The extent of surgical resection was 100% higher in both groups, and the treatment group was comparable to the control group. The prognosis of patients after the operation was poor. Nausea and vomiting, visual disturbance, upper vision paralysis, and ataxia in the treatment group were significantly lower than those in the control group, with no statistical significance (P > 0.05). At the same time, the bone window can be reduced to reduce trauma and provide a certain reference for patients to choose a safe and complete resection method.

Cerebellar pleomorphic xanthoastrocytoma in the setting of neurofibromatosis type-I: Does it portend a different prognosis? A case report and systematic review

The sacroiliac joint (SIJ) is anatomically and biomechanically unique and serves as a principal weight-bearing joint. Characterized as both diarthrotic and amphiarthrotic, its articular surfaces interlock to comprise a self-bracing joint that provides stability for the axial skeleton. The SIJ is innervated by the lateral branches of S1, S2, and S3 and more infrequently by L5 and S4. Etiology of SIJ pain includes trauma, structural abnormalities, previous lumbosacral fusion surgery, postpartum mechanical changes, and inflammatory diseases. Furthermore, pain from lumbar and hip pathologies may be difficult to distinguish from SIJ pain. Recent treatment for SIJ pain has expanded from conservative management to include SIJ fusion for intractable pain.
