“…The imaging appearance of SDHs may range from hyper to hypoattenuating crescentic collections along the inner table of the calvarium. Although acute bleeds are mostly hyperattenuating, mixed iso-or hypoattenuating blood is not always chronic and may represent hyperacute or unclotted blood, particularly in patients with underlying coagulopathies [44]. Looking for layering hematocrit levels can help identify such patients.…”

Traumatic brain injury is a common injury worldwide that affects individuals of all ages. Injuries can range in severity. Timely assessment of injury is important to triage cases that may be severe and imminently life-threatening, and neuroimaging is a critical component to the clinical care of such patients. Injuries may occur in multiple spaces from the extracranial soft tissues to the potential spaces between meningeal layers to the brain parenchyma itself. The neck and intracranial arterial and venous vessels can also be injured with devastating sequelae. CT, CTA, MRI, and MRA can all be useful in the assessment of head injury. In particular, CT is often used as a first-line imaging modality to screen for acute intracranial injury. MRI can be useful in patients who have discordance between symptoms and CT findings as well as in those with more prolonged symptoms or who suffer chronic sequelae of injury. Neuroimaging research is ongoing using MRI to study the underlying pathophysiology of head injury.

“…Sarcomas tend to affect pediatric or younger patients and are usually accompanied by systemic leukemia ( 20 ). Other differential diagnoses include empyema or granuloma, neurosarcoidosis, tuberculosis, inflammatory pseudotumor, idiopathic hypertrophic pachymeningitis and Rosai–Dorfman disease ( 5 , 12 – 14 , 16 , 18 , 19 , 21 , 22 ). Thus, when dealing with subdural masses, neurosurgeons should at least be reminded of the possibility of LRM, and further examinations such as enhanced MRI should be considered which would be helpful for the differential diagnosis.…”

“…Patients with subdural hematoma usually have a brain-trauma history, with surrounding edema on T2-weighted image and no enhancement on enhanced MRI. Subdural lymphomas tend to be primary ones such as mucosal-associated lymphoid tissue lymphomas, usually with nodular/lobulate borders and leptomeningeal extension (13)(14)(15)(16)(17). Dural metastasis lesions usually demonstrate hyperintensity on T2-weighted imaging and have a history of systemic primary neoplasm, especially from melanoma, breast, and prostate cancers (16,18,19).…”

Lymphoplasmacyte-rich meningioma (LRM) is a rare histologic subtype of meningioma. Creeping-growth pattern is uncommon in meningioma, and the mechanism is unclear. Here, we report a 44-year-old man presented with extremities weakness for 2 months and incontinence for 2 weeks. Head and neck MRI revealed diffuse creeping-growth nodular meningeal masses with skull base, tentorium, sella area, and C1-6 vertebral plane involvement. An operation was carried out, cervical and lower clivus part of the lesion was resected, but gross total resection could not be achieved due to the widespread lesions. Pathologic examination revealed the diagnosis of LRM. The patient is free from progression clinically 3 months postoperatively. We also conducted a systematic literature review about LRM with creeping-growth pattern. A total of only nine cases (including the present case) of creeping-growth LRMs were included and analyzed in terms of clinical manifestations, radiological features, treatment, and outcome. LRMs show a higher rate (7.5%) of creeping-growth pattern than other types of meningiomas. The average creeping length of all creeping-growth LRMs was 11.4 ± 10.9 cm (range, 3–30 cm). Most cases (66.7%) had obvious peritumoral edema. Total removal rate is low (33.3%), and two of them (22.2%) received biopsy, followed by steroids treatment (or further immunosuppressive drugs therapy) and radiotherapy. The recurrence rate is higher than conventional LRMs (22.2 vs. 11.3%), and one patient (11.1%) died 11 months after treatment. Creeping-growth pattern in LRM may be considered as a general radiologic variant. The recurrence rate is higher compared with LRM with round/swelling pattern. We speculated that the pathogenesis of creeping growth in LRM may be associated with damage of lymphatic systems of the central nervous system.
