RESUMO
Introduction and importance: Intracranial dermoid cysts (IDC) are defined as rare, slow-growing cystic congenital neoplasms. Rupture of an intracranial dermoid cyst occurs rarely and most often spontaneously and results in potentially serious symptoms. Case presentation: A39-year-old female, with mechanical prosthetic heart valve presented with history of headache for 10 months and generalized tonicoclonic seizures. On the admission, the patient had a normal neurological and cranial nerve exam. The authors performed a computed tomography of the brain, The MRI could not be performed because of the presence of the prosthetic valve, revealed rupture of the dermoid cyst in the bilateral subarachnoid spaces. The patient underwent a large temporal craniotomy and the tumour was well exposed and completely removed without incident, the histopathological examination concludes to dermoid cyst, the patient recovered well from surgery. Clinical discussion: Rupture is a very rare phenomenon. there are about 60 cases reported in the literature. the contents of the cyst disseminate into the subarachnoid and ventricular spaces in the event of rupture. A variety of clinical symptoms is usually caused. The mechanism of spontaneous rupture of the dermoid cyst is unclear. Among the proposed mechanisms is a rapid expansion of the cyst. Complete surgical resection of dermoid cysts is the only effective treatment for the prevention of recurrences and/or complications. Conclusion: Rupture of an intracranial dermoid cyst is associated with significant morbidity and mortality, although it remains a rare phenomenon. Surgical excision should be considered as soon as the diagnosis is made in order to prevent more severe intracranial complication.
RESUMO
Otogenic frontal abscess is an uncommon location of otogenic abscess of the brain and constitutes less than 5%. And the orbital extension is even more exceptional. An 11-year-old child, presenting with a two-week-long history of an acute otitis badly treated. Admitted for headaches, fever, vomiting and left eyelid swelling. The preoperative CT scan revealed a left frontal epidural abscess associated to a sub-periosteal Abscess. The patient was operated on. A supraorbital incision through the eyebrows allowed the evacuation of the periorbital abscess and the cerebral empyema through a trephine hole. The patient received probabilistic intravenous antibiotic therapy with ceftriaxon, aminoglycoside and metronidazole. Then relay per os. Postoperative recovery was marked by disappearance of headaches at postoperative Day two and the periorbital edema at day six. The patient was discharged home at postoperative week four with oral antibiotic therapy. Three months postoperative months follow-up CT scan revealed a total radiological cleaning. Otogenic frontal abscess associated to orbital Abscess is extremely rare and should be considered in front of ophthalmological signs. The management is multidisciplinary, and the entry point treatment mustn't be forgotten.
RESUMO
Electrification accidents is a serious pathology due to the passage of an electric current through the body. The clinical manifestation is mainly represented by skin lesions with burners of different degrees however all the tissues of the body can be affected. The cerebral manifestation is a rare entity described in the literature. In this paper, we report the case of a patient with an electrocution accident manifested by an extradural hematoma who has not encountered a similar case described in the literature. We therefore present this case which poses a poorly understood pathophysiological problem.
