A reference handbook of the medical sciences, embracing the entire range of scientific and practical medicine and allied science . l, and radiatinginto the neck region, with marked stiffness of the neck,is of special im|)ortance. This headache may resem-ble that of cerebrospinal meningitis. Nausea, vom-iting, stupor, general imrest may be present, as alsofever; but it is to be borne in mind that many cere-bellar abscesses run for months without causing not constant signs, hemiparesis and hemi-asynergia are usually present on the same side as thelesion. Atrophy is not infrequently present in largerabscesses, and papilledema caused by pressure pro-duced by increase in the size of the abscess may in-crease the difficulty of differentiating from tumor. Actual puncture by special aspiration needle isadvisable to clear up the diagnosis in complicatedcases. Lumbar puncture should be resorted to, toexclude meningitis.
