Sacrococcygeal joint dislocation is very rare. There are seven cases of sacrococcygeal joint dislocation found in the literature; most are anterior, and only one prior case of posterior dislocation was reported involving the mid-coccygeal joint. Here, we report another case of posterior dislocation of the sacrococcygeal joint.

A 19 year-old female developed acute low-back and groin pain following a fall from the first floor. She was diagnosed with an unstable pelvic fracture along with posterior dislocation of the sacrococcygeal joint. The next day, after being hemodynamically stabilized, she underwent percutaneous fixation of the sacral fracture, while the sacrococcygeal joint dislocation was managed conservatively. Her pain decreased, and she was discharged on the third postoperative day and followed up to 6 weeks.

Most sacrococcygeal joint dislocations can be managed conservatively.

Multiple sclerosis (MS) is the most common immune-mediated inflammatory demyelinating disease of the central nervous system. Multiple brain and spinal tumors have been linked to MS, but a causal relationship between the two has not been determined. Here, we report a case of spinal meningioma in a patient with MS and review literature discussing the possible connection between these two disease entities.

A 58-year-old female with MS presented with a 1-year history of progressively worsening back pain in conjunction with worsening right upper and lower extremity weakness. The patient was diagnosed with MS 19 months prior and had multiple known demyelinating plaques in her cervical spine. New MRI revealed an intradural extramedullary thoracic tumor with characteristics consistent with meningioma. She underwent T6- T8 laminectomies for tumor resection and pathology confirmed the radiological diagnosis. At 3-month follow- up, the patient reported complete resolution of her back pain and persistence of weakness-related gait issues.

CNS neoplasms including meningioma should be considered in MS patients presenting with newly onset neurological symptoms not entirely consistent with demyelinating disease. Both disease processes should be addressed with appropriate long-term follow-up.

Malignant atypical teratoid rhabdoid tumor (ATRT) usually develops in children. ATRTs are rare in adults, with only one case in the literature describing involvement of the anterior skull base. These primary intracranial tumors are characterized molecularly as SMARCB1 (INI1) deficient. Different types of such SMARCB1-deficient tumors exist in adulthood, usually in the form of extracranial tumors. Very few cases of such a new entity, named SMARCB1-deficient sinonasal carcinoma have been described with intracranial penetration and involvement of the anterior cranial fossa.

A 36-year-old male presented with acute cognitive deterioration. Over few hours, he developed a fulminant herniation syndrome. Imaging showed a tumor in the anterior cranial fossa surrounded by massive brain edema. The tumor has destroyed the frontal bone with involvement of the nasal cavities and paranasal sinuses. The patient underwent emergent decompressive craniectomy and tumor debulking but could not be saved. Pathological analysis rr cranial fossa and the paranasal sinuses. The main differential diagnosis of aggressive, primary, intracranial SMARCB1-deficient tumors in adults includes ATRT, SMARCB1- deficient sinonasal carcinoma, rhabdoid meningioma, and rhabdoid glioblastoma. Atypical tumors involving the anterior skull base without a clear histopathological pattern should therefore be checked for SMARCB1 expression.
Cerebrospinal fluid (CSF) fistula represents a rare neurosurgical entity that can be defined as a communication between the subarachnoid space and nasal fossa or less commonly the ear cavity. It can be spontaneous without an evident etiology or secondary following a skull base surgery or trauma. The early diagnosis of spontaneous forms remains a challenge as clinical signs (e.g., unilateral rhinorrhea) can be absent or neglected by patients and can result in meningitis.

Here, we report the case of a 31-year-old man with chronic constipation complicated by chronic intracranial hypertension, and resulting in rhinorrhea with bacterial meningitis. The etiological assessment of chronic constipation retained an autonomic dysfunction with sympathetic hyperactivity (e.g., pure autonomic failure) as an underlying cause. Beta-2 transferrin testing associated with cerebral magnetic resonance imaging and computed tomography scan confirmed the diagnosis and localization of the fistula at the cribriform plate. The patient underwent an endoscopic endonasal approach with a repair of fistula. He presented with recurrent rhinorrhea 17 months later which required a surgical revision along with CSF diversion with a ventriculoperitoneal shunt.

Although rare, autonomic dysfunction can result in chronic constipation in young patients, with intermittent or permanent intracranial hypertension, leading to CSF leaks. The early identification and treatment of the underlying etiology may prevent severe complications and improve the management and outcome of CSF fistula patients.

Cerebral venous sinus thrombosis (CVST) is a rare and often misdiagnosed condition with mortality rates ranging from 6 to 10%. Diagnosis and monitoring are typically achieved through noninvasive imaging, including computed tomography or magnetic resonance venography. The current standard of treatment is systemic anticoagulation. However, in patients who continue to decline neurologically or do not show sufficient response to or have absolute contraindications to systemic anticoagulation, endovascular treatments are an alternative. Endovascular options are poorly studied and specific devices have not been developed, partially due to the rare nature of the disease. Here, we present a case report detailing the treatment of extensive CVST from the vein of Galen to the sigmoid sinus using mechanical thrombectomy and local infusions of unfractionated heparin (UFH) and tissue plasminogen activator.

A 53-year-old man presented and was found to have extensive CVST extending from the vein of Galen to the left sigmoid sinus. Systemic UFH was begun; however, his condition continued to decline, and he was taken for endovascular intervention, wherein mechanical thrombectomy was undertaken using combinations of stent retrievers and balloon catheters, which provided acceptable revascularization. Unfortunately, his hospital course was further complicated by a cerebellar hematoma that was surgically evacuated and reocclusion of the sinus for which a microcatheter was placed for infusion of UFH and tissue plasminogen activator.

Complicated CVST may require aggressive endovascular management. Local infusions of heparin and thrombolytic agents as well as mechanical thrombectomy are safe alternative options.

Patient satisfaction questionaries have become popular in the past decade after the institution of the Patient Care and Affordable Care Act of 2010. This study evaluated whether the Hospital Consumer Assessment of Healthcare Services (H-CAHPS) and Press Ganey scores improved after institutional changes to the rounding system.

In the summer of 2017, utilizing H-CAHPS and Press Ganey scores, we asked whether switching from mid-level rounding providers to resident physicians improved patient care. Pre- and post-intervention groups, each lasting four quarters, were divided into care provided by mid-level personnel versus residents. For these periods, H-CAHPS respondent data were compared by a Chi-squared test (
< 0.05), while Press Ganey responses were analyzed with an independent samples
-test (
< 0.05).

Significant improvement was noted in patients answering "Definitely yes" in recommending our institution in both H-CAHPS and Press Ganey satisfaction surveys. Significant improvement regarding the speed of discharge, instructions for post-hospital care, and the overall rating of care given was observed in the Press Ganey responses alone.

Significant improvement in satisfaction was noted in the Press Ganey responses regarding the discharge process and speed of discharge. The quality of this last encounter likely contributed to+ the significant improvement observed in both the H-CAPHS and Press Ganey Scores for an overall hospital stay and the percentage of those definitely recommending our institution.

Perivascular spaces are interstitial fluid-filled regions located deep to the pia mater. They play roles in lymphatic drainage and the central nervous system immunological function. When they enlarge, they are referred to as giant tumefactive perivascular spaces. check details Often misdiagnosed as cystic neoplasms, they require a high degree of clinical suspicion and key radiological features to be accurately diagnosed. We describe an interesting case in which a man presented with worsening headache, subsequently found on neuroimaging to have this phenomenon.

A 32-year-old man with low testosterone presented to the ER for worsening headache, blurred vision, and photophobia. Computed tomography of the brain showed hydrocephalus with follow-up magnetic resonance imaging revealing several enlarged cystic spaces within the brain, concerning for neoplasm. He ultimately left against medical advice before the further evaluation was done. He followed up with a neurosurgeon as an outpatient, where further review showed characteristic features indicative of giant tumefactive perivascular spaces, thus avoiding the need for unnecessary biopsy and potential surgery.

Often misdiagnosed as cystic neoplasms, giant tumefactive perivascular spaces are benign processes that can have a broad presentation with the most common finding being a headache. Key radiologic features, including smooth margins, isointensity to cerebrospinal fluid, and lack of postcontrast enhancement, are crucial to diagnosis, preventing unnecessary surgery with increased morbidity.
