    The lateral lobes of the cerebellum possibly because of their greater size, seem to be more frequently the seat of tumors than the middle lobe, although writers differ upon this point. Tu- mors within the middle cerebellar peduncle are rarely found, although a tumor within this peduncle is present in one of the specimens in the laboratory. Growths in the anterior and posterior cerebellar peduncles are also uncom- mon. The angle formed by the cerebellum, me- dulla oblongata, and pons is a favorite seat for new growths, these tumors growing either from within or upon the acoustic, facial, or trigeminus nerves, and frequently are fibromata. Tuberculoma.—In 152 tuberculous brain tumors collected by Allen Starr, occurring in childhood, 47 were in the cerebellum. In the adult they are found with equal frequency in this region and in the pons and the cerebral cortex. They are nearly always multiple, and secondary to a tuber- culous process elsewhere in the body. A tend- ency to symmetrical arrangement is also ob- served (Oppenheim). Their size varies from a small nodule to a large fist. Macroscopically, it is hard to distinguish a tuberculoma from a syph- iloma. Both have poor blood supply and a tend- ency to caseate, the tuberculous growth to pus formation. Again, both have a tendency to grow
