Occurrence within the cranial vault is extremely rare, and their pathological nature, particularly in the absence of cortical disruption, remains controversial.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"st2\">\n                    <jats:title>Case Description:<\/jats:title>\n                    <jats:p>A 24-year-old man presented with a radiolucent intradiploic lesion of the left frontal bone following a minor head trauma sustained during a basketball game. Computed tomography demonstrated a well-circumscribed osteolytic lesion with preservation of both the inner and outer cortical tables. Magnetic resonance imaging showed T2-weighted hyperintensity resembling cerebrospinal fluid with no diffusion restriction, suggesting a benign process; however, Langerhans cell histiocytosis could not be definitively excluded. Magnetic resonance imaging showed signal characteristics suggestive of a benign process; however, Langerhans cell histiocytosis could not be definitively excluded. Owing to diagnostic uncertainty and patient-specific factors, a surgical biopsy was performed. Histological examination revealed fibrous marrow replacement, hemosiderin deposition, and multinucleated giant cells, without an epithelial lining or evidence of neoplasia, supporting the diagnosis of a cyst-like intraosseous lesion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"st3\">\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>This case represents a post-traumatic intraosseous cyst-like lesion within the spectrum of TBCs. It highlights the diagnostic challenges posed by radiolucent intradiploic skull lesions and underscores the importance of cautious interpretation, correlation between imaging and histopathological findings, and individualized clinical decision-making.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.25259\/sni_869_2025","type":"journal-article","created":{"date-parts":[[2026,5,15]],"date-time":"2026-05-15T06:48:46Z","timestamp":1778827726000},"page":"286","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Posttraumatic intradiploic cyst-like lesion of the frontal bone without cortical disruption: A case report"],"prefix":"10.25259","volume":"17","author":[{"given":"Chika","family":"Watanabe","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Tsukuba Memorial Hospital, Tsukuba, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kiyoyuki","family":"Yanaka","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tsukuba Memorial Hospital, Tsukuba, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minami","family":"Saura","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tsukuba Memorial Hospital, Tsukuba, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuyuki","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Radiology, Tsukuba Memorial Hospital, Tsukuba, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sho","family":"Hanai","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tsukuba Memorial Hospital, Tsukuba, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshihide","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tsukuba Memorial Hospital, Tsukuba, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hitoshi","family":"Aiyama","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tsukuba Memorial Hospital, Tsukuba, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noriaki","family":"Sakamoto","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Pathology, University of Tsukuba, Tsukuba, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eiichi","family":"Ishikawa","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Tsukuba, Tsukuba, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2026,5,15]]},"reference":[{"key":"10.25259\/SNI_869_2025\/ref-1","doi-asserted-by":"crossref","first-page":"145","DOI":"10.14219\/jada.archive.1976.0297","article-title":"Traumatic cyst of the jaws: Report of 30 cases","volume":"92","author":"Beasley","year":"1976","journal-title":"J Am Dent Assoc"},{"key":"10.25259\/SNI_869_2025\/ref-2","doi-asserted-by":"crossref","first-page":"927","DOI":"10.1007\/s00701-003-0114-2","article-title":"Simple bone cyst occurring in calvarium","volume":"145","author":"Chang","year":"2003","journal-title":"Acta Neurochir (Wien)"},{"key":"10.25259\/SNI_869_2025\/ref-3","doi-asserted-by":"crossref","first-page":"10083","DOI":"10.1038\/s41598-022-13264-4","article-title":"Analysis of the fluid contents of simple bone cyst in the mandible","volume":"12","author":"Choi","year":"2022","journal-title":"Sci Rep"},{"key":"10.25259\/SNI_869_2025\/ref-4","first-page":"E239","article-title":"Traumatic bone cyst: A retrospective study of 21 cases","volume":"14","author":"Cortell-Ballester","year":"2009","journal-title":"Med Oral Patol Oral Cir Bucal"},{"key":"10.25259\/SNI_869_2025\/ref-5","doi-asserted-by":"crossref","first-page":"126","DOI":"10.1590\/0100-3984.2016.0166","article-title":"Post-traumatic intraosseous leptomeningeal cyst","volume":"51","author":"De Ara\u00fajo Neto","year":"2018","journal-title":"Radiol Bras"},{"key":"10.25259\/SNI_869_2025\/ref-6","doi-asserted-by":"crossref","first-page":"45","DOI":"10.1038\/nrrheum.2014.164","article-title":"Fracture healing: Mechanisms and interventions","volume":"11","author":"Einhorn","year":"2015","journal-title":"Nat Rev Rheumatol"},{"key":"10.25259\/SNI_869_2025\/ref-7","doi-asserted-by":"crossref","first-page":"3027","DOI":"10.21608\/edj.2017.76088","article-title":"Traumatic bone cyst of the mandible; Diagnostic challenge and management a case report","volume":"63","author":"Elsagali","year":"2017","journal-title":"Egypt Dent J"},{"key":"10.25259\/SNI_869_2025\/ref-8","doi-asserted-by":"crossref","first-page":"244","DOI":"10.2176\/nmc.27.244","article-title":"Solitary Bone cyst in the skull.
