“…Rarely, epidermoid cysts arise in the cranial diploe of the middle ear region or frontal bone, where they present as a lytic defect. Unlike dermoid cysts, epidermoid cysts often occur laterally, without a preference for midline sites (1,4,8,10,13) .…”

Epidermoid cysts of the central nervous system are uncommon conditions, which are frequently located in the cerebellopontine angle and around the pons. They are covered with keratinized squamous epithelium and keratin lamella, which give its contents a soft, white-pearly appearance. Epidermoid cysts are mostly originated from malformations, presumably associated with surface elements of the nervous system ectoderm during the closure of the neural groove or formation of secondary cerebral vesicles. The authors describe a case of epidermoid cyst in the posterior fossa causing hydrocephalus and review morphologic and diagnostic criteria of this lesion.

“…Also other underlying causes such as cyanotic heart disease, shunt infection, meningitis, and cranial dermal sinuses have been reported (Ersahin and Mutluer 1994;Brook 1995;Akhaddar et al 2002). In about 5% of patients the source of infection remains unknown, namely, cryptogenic brain abscess (Moss et al 1988;Ersahin and Mutluer 1994).…”

Brain abscess as a manifestation of spinal dermal sinus

Dermal sinuses have been associated with a wide spectrum of clinical manifestations ranging from asymptomatic to drainage of purulent material from the sinus tract, inclusion tumors, meningitis, and spinal abscess. To date, there has been no documented report of brain abscess as a complication of spinal dermal sinus. Here, we report an 8-month-old girl who was presented initially with a brain abscess at early infancy but lumbar dermal sinus and associated spinal abscess were discovered afterwards. The probable mechanisms of this rare association have been discussed.

“…They arise from inclusion of ectodermal elements within the neural tube during its closure between the 3rd and 5th week of embryonic development [3]. They mostly occur in the posterior fossa, particularly in the midline position in the vermis or adjacent meninges, or in the cavity of the fourth ventricle [3, 17].…”

“…More rarely, dermoid cysts may communicate with the skin through a narrow tract lined by epithelium (dermal sinus) which, therefore, contains the glandular architecture of the skin, promoting colonization by microorganisms. Microorganisms may travel into the cyst with the potential risk of deeper suppurations through this communication [3, 4]. The meningitic presentation of dermal inclusions around the occipital protuberance, particularly atypical staphylococcal or Gram-negative forms, is commonly reported [5].…”

Posterior Fossa Dermoid Cysts Causing Cerebellar Abscesses

et al. 2007

Dermoid cysts are uncommon tumors, and posterior fossa dermoid cysts may rarely cause abscess formation or formation of daughter abscesses within the cerebellum. At present, there are only 16 cases with posterior fossa dermoid cysts causing cerebellar abscesses reported in the literature. Two cases, 22 and 14 months old, with posterior fossa dermoid cysts and dermal sinus causing multiple cerebellar abscesses are reported. In the first one, there was also marked hydrocephalus. Retrospective examination of the patients revealed pinpoint-sized dimples in their suboccipital regions. Both patients were treated with antibiotics and underwent posterior fossa surgery. In the patient with marked hydrocephalus, ventriculoperitoneal shunting was performed after treatment of the infection. Both patients were neurologically normal, and there were no complaints, except a light learning difficulty in the patient with ventriculoperitoneal shunting, 133 and 34 months after surgery, respectively. Early detection of congenital dermal abnormalities along the craniospinal axis by routine examination of newborns is highly important before development of serious complications. Because surgery is the only effective treatment modality for these lesions, radical excision should be performed in all cases to avoid tumor recurrence. However, subtotal excision may be performed in selected cases, because the cyst capsule may adhere firmly to vital structures.
