ABSTRACT
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.
ABSTRACT
Hemorrhagic lesions in CNS lymphoma are extremely rare. We report the case of a 75-year-old patient admitted to the emergency room following a classic hemorrhagic stroke. The CT scan showed a hyperdense tumor-like process with perilesional edema, the diagnosis reinforced by (MRI). The patient underwent macroscopically total surgical excision and the anatomo pathological examination concluded a diffuse non-Hodgkin's B large cell lymphoma. The follow up was marked by a clear clinical improvement. Primary cerebral lymphomas can be polymorphic, so this diagnosis should always be kept in mind during stroke manifestations. This case illustrates the diagnostic difficulty of this rare and poor prognosis condition.
