[Pseudotumor cerebri due to taking minocycline].

The cerebral pseudotumor (PTC) is defined by the increase in cerebrospinal fluid (CSF) pressure, a normal composition of the latter in the absence of identified intracranial structural abnormalities, in particular by neuroimaging. The pathophysiology of PTC is poorly understood although its diagnostic criteria are well established. Drugs such as minocycline, tetracycline and doxycycline have been repeatedly implicated as a causative factor in PTC. The prognosis of PTC related to minocycline, reported in the literature is quite variable. Some authors suggest a benign condition with spontaneous healing by stopping the antibiotic, while others report permanent loss of vision. A 12-year-old girl is admitted to the emergency room for progressively progressive pulsatile temporal headaches associated with diplopia. The patient reported the use of minocycline 50 mg / d for five months, prescribed by her attending physician as part of an acne treatment. PTC will be demonstrated by severe papillary edema and cerebral NMR will demonstrate an enlargement of the subarachnoid space around the optic nerves. After three lumbar punctures, the condition of the patient stabilized and there was a marked improvement in headache despite the persistence of bilateral papillary edema. This work describes a clinical case of PTC induced by the use of minocycline and reviews the physiopathology, the diagnosis and the management of this one.
