Rare Brain Tumors with Infrequent Clinical Manifestations: Illustrative Cases By José Luis Navarro-Olvera, Armando Armas-Salazar, José Damián Carrillo-Ruiz, Jesús Q . Beltrán, Gustavo Parra-Romero and Gustavo Aguado-Carrillo
This chapter describes the epidemiology, clinical and neuroimaging features, histological characteristics, surgical approach, outcomes, and prognostic factors of different cases of very rare intracranial tumors, associated with complex clinical syndromes. Highlighting the important aspects in the diagnosis and management that were considered relevant through the experience of our center. Here we included an intracranial Rosai-Dorfman disease manifested as an apparent multiple meningiomatosis, a choroid plexus papilloma clinically manifested as a hemifacial spasm originated by a compression of the facial colliculus, and a neuroenteric cyst associated with Klippel-Feil syndrome. This type of tumor presents a challenge to the neurosurgeon, originating various questions about its management. In this chapter, we present the experience we had with these pathologies to establish the most appropriate management decisions.

Usefulness of Intraoperative 2D-Ultrasound in the Resection of Brain Tumors By José Luis Navarro-Olvera, Armando Armas-Salazar, Jesús Q. Beltrán, Gustavo Aguado-Carrillo, Fiacro Jiménez-Ponce, Edgar Abarca-Rojano and José Damián Carrillo-Ruiz
The surgical approach to brain tumors often uses preoperative images to visualize the characteristics of pathology, guiding the surgical procedure. However, the usefulness of preoperative images during the surgical procedure is altered by the changes in the brain during the surgery because of craniotomy, inflammation, tumor resection, cerebrospinal fluid (CSF) drainage, among others. For this reason, there is a need to use intraoperative imaging evaluation methods that allow the surgeon to consider these changes, reflecting the real-time anatomical disposition of the brain/tumor. Intraoperative ultrasound (iUS) has allowed neurosurgeons to guide the surgical procedure without exposing the patient to ionizing radiation or interrupting the procedure. Technological advances have made it possible to improve image quality, have smaller probes, and facilitate the use of the equipment, in addition to the introduction of new imaging modalities, such as three-dimensional images, enhanced with contrast, among others, expanding the available options. In the context of these advances, the objective of this chapter was to review the current status of the usefulness and challenges of iUS for brain tumor resection through an in-depth review of the literature and the discussion of an illustrative case.

Brachial plexus injuries (BPI) affect mostly the young population. The management of these injuries is complex and there are many surgical options for treatment. To evaluate the patient motor component, the British Medical Research Council motor grading scale (BMRC), range-of-motion (ROM), disability of the arm, shoulder, and hand questionnaire (DASH), and push and pull dynamometer are the main clinical assessment tools that provide information about the clinical status regarding motor function. The purpose of this chapter is to show the motor recovery on interventions that are available as surgical alternatives for the management of BPI, through a systematic review of the literature.
