Although several investigations have examined the epidemiology of cervical spine injuries in sports, few studies have analyzed the nationwide incidence and sex-specific epidemiology of cervical spine injuries. ⋯ Football is the leading cause of cervical sprains in the United States. The most common cause of cervical fracture in men is cycling, while in women it is horseback riding. The incidence of sport-related cervical fractures has increased by 35% from 2000 to 2015, which has been driven by an increase in cycling-related injuries.

Sellar germ cell tumors (GCTs) occur more frequently in childhood. Some will present as malignancy with infiltration and metastasis. However, the association between the timeliness of diagnosis and outcome has been controversial. We investigated the clinical risk factors associated with a diagnostic delay in patients with sellar GCTs in China. ⋯ A significant proportion of patients with sellar GCTs will experience a delay in the time to diagnosis. Although a delay in diagnosis did not reduce the survival time or progression-free survival time for patients with sellar GCTs, it might increase the risk of short stature. Thus, a detailed medical history and an immediate radiological examination are important for the early diagnosis of sellar GCTs in childhood.

Many researchers have found a correlation between tortuous arteries and development of aneurysms in cerebral arteries. However, there are no studies analyzing the impact of tortuosity on risk of subarachnoid hemorrhage (SAH) occurrence. Therefore, we decided to determine whether tortuosity of the anterior cerebral artery can be related to the rupture of anterior communicating artery aneurysm and to severity and treatment outcome of SAH. ⋯ Higher anterior cerebral artery tortuosity might be a protective factor against anterior communicating artery aneurysm rupture.

Primary dural-based lymphoma is a rare disease entity. It has been hypothesized that patients with sarcoidosis are at increased risk of developing lymphoma, an association known as "sarcoidosis-lymphoma syndrome," although dural disease has not yet been reported in the literature. ⋯ Given the association between sarcoidosis and lymphoma, we suggest lymphoma to be considered as one of the top differentials for a dural-based mass lesion in patients with sarcoidosis.

Double crush of a nerve at the root level is not common. We describe here a double crush of the right L4 nerve with foramina to far lateral disk (ventral) and extraforaminal (dorsal) compression. The double crush was managed by endoscopy with a contralateral uniportal approach from the left interlaminar space. Right lateral recess stenosis at the same level was subsequently managed with the same approach. ⋯ We conclude that the management of double crush at the nerve root level with interlaminar contralateral approach endoscopy (percutaneous endoscopic contralateral interlaminar foraminotomy) can deal with the issue effectively with facet joint preservation and other benefits of the minimally invasive spine procedure.
