Neglected Case of Primary Intraorbital Hydatid Cyst.

Background: Hydatid cyst is a parasitic infection caused by Echinococcus granulosus and human is an accidental host. Liver and lungs are the most widely recognized organ of association but relatively low in other organs. Orbital involvement of the hydatid cyst is rare. Case Description: The case was a 47-year-old lady presented in the late stage of disease when corneal ulcer had developed and with complete vision loss along with headache, proptosis, and pain in the left eye. Cystic lesion in the retro-orbital region of the left eye was revealed by Computed tomography scan and magnetic resonance imaging. The patient underwent surgery. Hundreds of daughter cysts were seen intraoperatively and cyst wall sent for histopathological examination to confirm the diagnosis. The patient was further treated with albendazole for 3 months. Conclusion: Although hydatid cyst is uncommon, it ought to be considered in the differential diagnosis of cystic lesion of orbital locale, more so in the endemic territories.

Posttraumatic Bilateral Epidural Hygroma of the Posterior Cranial Fossa: Case Report and Brief Review of Literature.

BACKGROUND: Posttraumatic posterior fossa epidural hygroma is a rare entity, and a clear management has not been established in the medical literature. We present 1 case and review the literature relevant to this unusual entity. The mechanism of formation and management of posterior cranial fossa epidural hygroma are also outlined. CASE DESCRIPTION: A 2-year-old child presented after a rooftop fall injury with symptoms of headache, drowsiness, vomiting, and brief loss of consciousness. Computed tomography scan demonstrated swelling in the left occipital region and epidural hygroma. After conservative management failed, surgical repair of the dura mater was performed. The child was discharged postoperative day 11 in stable condition with marked improvement in occipital swelling. CONCLUSIONS: It is imperative to consider epidural hygroma in very small children presenting with occipital injury. As a result of loose adhesion of dura mater and internal cranial lamina layers in younger pediatric patients, potential epidural space may be easily created secondary to injury, and small breaches in meningeal integrity near the cisterna magna may favor cerebrospinal fluid leak. During surgery, if watertight repair of a visible dural tear is performed, duro-periosteal hitching or vacuum drain placement may not be required.
