Chronic subdural hematoma (CSDH) is the most common disease encountered in neurosurgery. Diagnoses of CSDH are usually made on the basis of computed tomography (CT) images. In this report, we discuss the case of a patient with meningioma whose findings instead suggested CSDH. ⋯ In almost all cases, CSDH can be diagnosed using CT images only. However, our patient's true diagnosis was meningioma, rather than CSDH. We rouse attention not to take it for CSDH with a CT image easily.

For patients undergoing lumbar spinal surgery, many surgeons routinely perform laboratory tests within 3 days after surgery. However, few studies have reported the necessity for routine laboratory tests for patients with uncomplicated cases within 3 days after surgery. ⋯ Owing to the small number of postoperative clinical interventions for abnormal laboratory test results, we believe that the use of routine laboratory tests within 3 days after lumbar spinal surgery for patients with uncomplicated cases are unnecessary. Our results showed that operative time is a potential risk factor for the necessity for clinical treatment after lumbar spinal surgery.

Intracranial germ cell tumors are a rare group of neoplasms constituting 1% to 2% of primary intracranial tumors in North America and Europe. Germinomas of the corpus callosum are exceedingly rare, accounting for only 0.7% of all intracranial germ cell tumors. ⋯ This is a case of germinoma arising in the corpus callosum that presented clinically with an eating disorder manifested as restrictive anorexia.

Secondary brain injuries, such as delayed cerebral infarction (DCI), are the leading causes of disability after subarachnoid hemorrhage (SAH). Detecting DCI may be challenging, especially for patients presenting an altered level of consciousness. ⋯ Multiple secondary complications (DCI, seizures, hydrocephalus) may occur after SAH but are clinically difficult to diagnose. A multimodal evaluation (transcranial Doppler, CT or magnetic resonance imaging, electroencephalography) is useful in order to detect and treat late complications.

Persistent primitive trigeminal artery (PPTA) is a rare abnormal carotid-basilar anastomosis. In rare circumstances, PPTA can be associated with some cerebrovascular anomalies, including arteriovenous malformation, intracranial aneurysm, carotid cavernous fistula, and moyamoya disease (MMD). ⋯ The pathogenesis of the coexistence of PPTA and MMD, PPTA and intracranial aneurysm, and MMD and intracranial aneurysm is still unknown. According to the literature, congenital factor and hemodynamic stress may play an important role in the formation of these vascular anomalies. In case of hypoplasia of the vertebrobasilar system, PPTA could also be used as a route for endovascular coiling for some specific aneurysms in the posterior circulation. To our knowledge, this is the first report of such a case.
