Lateral Sinus Thrombosis as a Sequela of Chronic Mastoiditis

Lateral sinus thrombosis (LST) is a known but rare complication of chronic otitis media and mastoiditis in the antibiotic era. The classic symptoms of picket fence fever and other unspecific symptoms could be masked by the usage of the antibiotics contributed to the late presentation and delay in treatment. Thus, clinicians should be vigilant and detect this complication early to prevent mortality and morbidity. Administration of broad-spectrum antibiotics and surgical mastoidectomy to eradicate the perisinus infection are the main treatment modalities. Here, we report a case of partially treated chronic otitis media complicated with LST after a 6 months gap of defaulted follow-up.
