“…4,6) In the present case, breast cancer was previously diagnosed, and subsequently bone scintigraphy showed a hot spot consistent with the radiological findings of an intradiploic cyst. Such a hot spot in the bone scintigraphy scan is not necessarily diagnostic of a malignant tumor, because benign tumor, fracture, or inflammation may also show up as a hot spot, so the preoperative diagnostic imaging findings could not exclude a metastatic lesion to the skull.…”

“…1,4) However, the present case of intradiploic epithelial inclusion cyst lined with ciliated epithelium is extremely rare, and the histology was completely different from the squamous cell lining of epidermoids. In a case of ciliated epithelium cyst of the skull, the lining was histologically compatible with the epithelium of upper respiratory tract, which was the only previously reported case of intradiploic ciliated epithelium inclusion cyst.…”

“…Intradiploic epithelial inclusion cysts are considered to be mainly primary and congenital in origin, theoretically derived from misplaced cell rests during weeks 3 to 5 of embryogenesis. 4) The inclusion of ectodermal cells causes epidermoid or dermoid tumor, whereas the involvement of dysplastic neuroectodermal, mesodermal, and/or endodermal cells causes teratoma. 3,5) The ectopic stem cells may also be transported accidentally later in fetal development, by tagging along during invagination of the optic vesicles or be pinched off during development of the sutures, meninges, or diploe.…”

“…1,4) Lytic defects in the skull bone are also associated with epidermoid cysts, dermoid cysts, hemangiomas, eosinophilic granulomas, and others. 1,4,6) The differential diagnosis of circumscribed lytic defects of the skull includes benign cysts as well as neoplasms. A definitive diagnosis can only be made by performing an open biopsy.…”

Fig. 1 Bone window computed tomography scan demonstrating osteolytic changes with bulging of the inner and outer tables (arrow). 270 CASE REPORT AbstractA 56-year-old woman presented with a cystic skull lesion in the right temporal bone detected after resection of breast cancer. She underwent resection of the skull tumor for pathological diagnosis and treatment. The tumor was covered with ciliated epithelium and there were no malignant findings. The pathological diagnosis was ciliated epithelial inclusion cyst. Intradiploic inclusion cysts of the skull presenting as a calvarial defect include epidermoid cysts and dermoid cysts, which are clinically difficult to differentiate. Ciliated epithelium lining an intradiploic inclusion cyst is very rare. Surgical resection is essential for a definitive diagnosis and differentiation from a neoplasm.

A 36-year-old man presented to the emergency room with a complaint of severe headache that persisted for several hours. He had been suffering from unremitting, low-intensity headaches, treated with nonsteroidal anti-inflammatory drugs. The patient denied experiencing any previous brain trauma. Computed tomography (CT) without contrast administration revealed an expansive mass in the skull, centered on the left parietal bone.The mass was inhomogeneous with a mean density of 12 HU. Higher-density linear strands, without enhancement after administration of contrast medium, were visible at the periphery of the mass. The outer table of the skull was thin but continuous, whereas the inner table was barely visible. The mass displaced the contiguous parietal and frontal lobes of the brain (Fig. 1).At MRI, two distinct lesions were present: an inhomogeneous intradiploic mass and, inferior to this mass, an arachnoid cyst of the middle fossa of the brain. T2*-weighted sequences showed no traces of bleeding within the intradiploic mass (Fig. 2).The diagnosis can be found at
