“…While midline dermoids are not infrequently found to invade the cranium, there are fewer than 20 case reports which describe lateral frontotemporal dermoids with associated sinus tracts and bony invasion, of which 7 have extended intracranially [1,2,5,7,8,9,10,11,12,13,14,15]. Intradiploic dermoids represent between 0.04 and 0.7% of all cranial tumors [17].…”

“…They may appear as a lytic defect in the skull, giving a wide differential diagnosis by imaging alone. Frontotemporal dermoid cysts associated with sinus tracts or bony invasion are extremely rare, with only 20 case reports described in the literature [1,2,5,7,8,9,10,11,12,13,14,15]. We present a report of a rare intradiploic frontotemporal dermoid, without soft tissue extension, in the cranium of a 2-year-old male.…”

“…Dermoids represent approximately 1% of all craniofacial space-occupying lesions and are commonly found in the periorbital, nasoglabellar, and frontotemporal regions [1]. While dermoid cysts are slow-growing in nature, they can be associated with serious complications [2,3,4,5,6]. These lesions comprise a spectrum of conditions ranging from simple localized cysts to complex lesions with fistula formation and intracranial extension [4].…”

Background: Intradiploic dermoid cysts represent 0.04-0.7% of cranial tumors. Fewer than 20 cases of dermoid cysts occurring in the lateral frontotemporal region with a sinus tract and bony involvement are described, only 7 with intracranial extension. We present the first report of such a lesion arising within the lateral coronal suture. As the literature on this topic grows, the matter of preoperative imaging for soft tissue and bony lesions of the lateral frontotemporal region is evolving, and this report offers a preliminary set of criteria for when imaging is a necessity. Case Report: A 2-year-old male presented with a bony lesion in the right frontotemporal region. Since birth the lesion had grown commensurately with the patient. Examination revealed an immobile hard mass overlying the right coronal suture with no discernable abnormality. Computed tomography demonstrated a cystic lesion without evidence of intracranial extension. Intraoperatively, the exophytic lesion was fully enclosed by bony matrix, interrupting the coronal suture as it approached the pterion. Following resection, pathology revealed an intradiploic dermoid cyst. Conclusion: Intradiploic dermoid cysts occurring within patent cranial sutures away from the midline are rarely described lesions. Complete surgical resection with careful follow-up is the treatment of choice.

“…However, case reports of nonmidline cranial DSTs have also been published. These lesions mostly involve the anterior temporal region [2,4,10,11,12,13]. In our series, there were 4 lateral DSTs, which were retroauricular in 2 and in a lateral temporal area (pterional) in the other 2 instances.…”

Objective: Cranial dermal sinus is a very rare anomaly mostly found in the midline occipital area, presenting with diverse clinical features from asymptomatic dermal sinus to symptomatic situations including meningitis, dermoid tumor or abscess. Methods: Medical records of 18 patients with 19 cranial dermal sinuses operated at the Children’s Hospital Medical Center in Tehran from 1999 to 2011 were retrospectively studied. Their presentations, accompanying anomalies, radiological and surgical findings were evaluated. Results: Patients were aged 1 month to 6 years and were followed for 2–12 years. Most sinuses were located in the midline occipital region. Infection was the most common reason for referral (50%) followed by skin dimple (33.3%). Creamy white discharge was found in 50% of patients. Posterior fossa abscess, hydrocephalus and meningitis were observed in 38.9, 38.9 and 22.2% of children, respectively. All sinus tracts with associated dermoid tumors or abscesses were removed en bloc to decrease the risk of recurrence. Conclusion: The sinus tracts are a portal of entry for pathogens which result in serious complications of meningitis or abscess. In this series, 67% of children presented with serious symptoms; therefore, we recommend prophylactic surgery in all cranial dermal sinuses. The exact time of surgery is not obvious as the natural course of the disease is unknown. If any symptom is observed surgery should be done as soon as possible. For asymptomatic sinuses identified by the pediatrician during a regular visit prophylactic surgery is recommended as soon as the child can tolerate operation.

“…While dermoid cysts with temporal bone invasion have been reported in the literature, our review yields only rare studies of dermoids invading the greater wing of the sphenoid [8,9,10,11] and none of a bilobed sphenoid wing dermoid such as the one described here. Intraorbital extension, which is also rare, has been reported in conjunction with dermoids of the temporal bone [12,13,14].…”

Craniectomy for a Bilobed Dermoid Cyst in the Temporal Fossa and Greater Wing of the Sphenoid Bone

Dermoid cysts are common periorbital lesions. They usually occur near the superolateral orbital rim, indenting but not extending within the bony outer table. We present an unusual case of a dumbbell-shaped dermoid cyst underlying the temporalis muscle with extension into the lateral wing of the greater sphenoid bone, approaching the optic canal. The cyst was successfully removed en bloc via a small skull base craniectomy without spillage of cyst contents. The patient recovered well without neurological or visual sequelae.
