RESUMEN
Surgery, more specifically transsphenoidal approach, remains the primary treatment chosen for the majority of pituitary tumors (except for prolactinomas where medical treatment is indicated) allowing for pathologic analysis and complete or partial tumor removal. Transcranial approaches, employing craniotomies, are still needed in some patients with giant pituitary adenomas and in many of those harboring craniopharyngiomas. However, the surgical treatment of pituitary tumors is challenging because of their complex anatomical location and their heterogenous histology. Due to the proximity of critical structures, a successful surgical procedure may often not be achievable due to the high risks related to the procedure itself. Therefore, the treatment of pituitary tumors in 2020 commonly requires a multimodal approach, including surgery, radiosurgery, radiation therapy, and medical therapy. Recently, efforts have been made to develop intraoperative imaging, by increasing the diffusion of radiosurgery. Furthermore, the development of Pituitary Tumor Centers of Excellence (PTCOE) is becoming crucial to provide the optimal treatment for a single patient. There is in fact sufficient evidence that the best and optimal outcome in terms of tumor resection and correction of hormonal over secretion as well as the lowest rate of complications are obtained in centers of excellence with sufficiently experienced, specialized surgeons and a high patient load. Technological developments will probably even gain increasing importance in the future.

Joseph Engel (1816-1899) was a Viennese anatomist and pathologist trained under the mentorship of Carl von Rokitansky (1804-1878), the man who laid the foundations of gross anatomical pathology. In 1839, Engel completed his first scientific project: the dissertation entitled "Über den Hirnanhang und den Trichter" (About the pituitary gland and the infundibulum). This work analyzed the pathological and clinical characteristics of the pituitary and infundibulum tumor specimens collected at the Vienna Pathologic-Anatomical Museum. This little-known work represents one of the earliest attempts to determine the function of the pituitary gland-infundibulum complex. Among the 12 pituitary/infundibulum tumors examined in Engel's dissertation, one of the cases (no. 10) was instrumental for the definition of hypophyseal duct tumors, or craniopharyngiomas (CPs). This huge cyst, approximately the size of a goose egg (6 × 6 × 4.5 cm), was found in 1828 during the autopsy of a 33-year-old patient who suffered from severe headache, blindness, apathy, and finally somnolence. The cyst had replaced the hypophysis and extended upwards into the hypothalamic region and downwards into the sphenoid sinus, its inferior pole protruding through the soft palate. In 1904, the Viennese pathologist Jakob Erdheim (1874-1937) re-examined this lesion and conclusively categorized it as a hypophyseal duct tumor after a detailed histological study. The original tumor specimen corresponding to this CP case is still preserved at the Narrenturm, the circular building within the old Allgemeines Krankenhaus (Vienna General Hospital) that today holds the pathological collections of Vienna's Federal Pathologic-Anatomical Museum. To the best of our knowledge, this tumor is very probably the oldest preserved whole CP specimen in the world. This paper presents a comprehensive review of Engel's dissertation, the pioneering pathological work on pituitary and infundibulum tumors which laid the groundwork for the proper clinical, topographic, and pathological categorization of craniopharyngiomas.

BACKGROUND Standard translations of Hippocratic works are sometimes misleading because the translators knew less about their subject than did the ancient authors. CASE REPORT A new translation and explication of a chapter from a Hippocratic work of the fifth century before the Common Era (BCE), Diseases II, describes patients with pituitary apoplexy and subsequent myxedema, the 2 events separated by as much as 14 years. CONCLUSIONS The association of myxedema with an intracranial event that occurred years earlier predates by 2400 years the causal association of a pituitary adenoma with hormonal deficiency.

In previous decades, extensive and disfiguring transfacial and/or transcranial approaches were used to reach the sellar and parasellar areas. However, these surgical routes were burdened by severe complications and high mortality rates. Recently, the development of endoscopic endonasal techniques has revolutionized the surgical strategies for approaching the sella and adjacent areas and increased the development of transsphenoidal surgery. With these techniques, surgeons have been able to overcome the visual limitations of the open surgical approaches and access areas previously hidden from view. After the contributions of the Pittsburgh duo, Carrau and Jho, pioneers of pure endoscopic surgery, our school began to implement this technique, introducing technical innovations and variations, describing the anatomical details and defining new routes, and playing a key role in its widespread clinical application.

This manuscript describes the study of two cases of craniopharyngioma, which have been examined repeatedly over three separate centuries. This includes analysis by Josef Engel in 1839, who sought to uncover the physiological role of the pituitary gland; Jacob Erdheim in 1904, who initially described the disease we now call craniopharyngioma, and recent high resolution MRI and micro-CT imaging and attempted DNA analyses of the tumours. The cases highlight how, rightly or wrongly, our interpretation of data is shaped by the technologies, methodologies and prevailing theories of a given time.

OBJECTIVE: Harvey Cushing (1869-1939) developed pioneering surgical techniques for craniopharyngioma (CP) removal. This study exhaustively analyzes the pathological variables and surgical strategies that influenced Cushing's results in his entire series of CP patients. METHODS: The CP records from Cushing's Brain Tumor Registry were carefully reviewed, as were his CP cases published in medical monographs and scientific reports. RESULTS: One hundred twenty-four tumors with characteristics typical of CP comprise Cushing's entire series (CP124). Cushing performed 198 surgical procedures in the patients in whom these tumors were treated, with a 23% mortality rate within the first 2 months after surgery. Three periods in Cushing's CP surgical career can be differentiated: an early period (1901-1917, 39 patients) characterized by his use of the transsphenoidal approach and limited cyst drainage procedures, an intermediate period (1919-1925, 42 patients) in which the subfrontal approach was the standard procedure and maximal removal was attempted, and a late period (1926-1932, 43 patients) characterized by the use of air ventriculography for topographical diagnosis and limited resections via a transventricular approach. Among Cushing's CP series were 92 cases that were pathologically verified (CP92). In this subcohort, the unilateral subfrontal approach was predominantly used (72% of cases), followed by the transsphenoidal (15%) and frontal transcortical-transventricular (8%) approaches. Drainage of the CP cystic component or partial excision of the solid component was achieved in 61% of the cases, subtotal removal in 23%, and macroscopic total removal in 10%. Satisfactory outcomes were obtained in 55% of the patients in CP92, whereas poor outcomes and/or death related to hypothalamic injury was observed in 28%. Postoperative symptoms related to hypothalamic dysfunction occurred 53% of the time. The subfrontal approach yielded the highest rates of radical removal (p < 0.001) and good outcomes (p = 0.01). Partial removals were associated with the highest rates of poor outcomes, including death (p = 0.009). Cushing's removal of CPs with a primary infundibulo-tuberal topography or showing third ventricle invasion was associated with the highest rates of hypothalamic injury (p < 0.001) and the worst outcomes (p = 0.009). CONCLUSIONS: Harvey Cushing's techniques and surgical philosophy varied substantially throughout his career. The experience he gained with this large CP series made him aware of the importance of limiting the extent of tumor removal and leaving untouched the tumor portion strongly adhered to the hypothalamus.

OBJECTIVE: Harvey Cushing (1869-1939) coined the term "craniopharyngioma" (CP) in 1929 to describe a kaleidoscopic group of epithelial tumors involving the hypothalamic-pituitary axis. Throughout his career, he endured a long struggle to accurately diagnose and safely remove these complex lesions, and his resulting surgical series has never before been analyzed in depth. The authors here conduct such an analysis. METHODS: In this study, the authors retrospectively examined the CP patient records available in the Cushing Brain Tumor Registry, as well as those CP cases reported by Cushing in medical monographs and scientific reports. RESULTS: Cushing's CP series comprises a total of 124 tumors (CP124) compatible with a CP diagnosis. Among this series are 92 cases that could be pathologically verified (CP92). This subcohort showed a bimodal age distribution (41% aged ≤ 19 years old) and a balanced sex distribution. Clinical evolution up to diagnosis was longer than 3 years in half of the patients. Typical symptoms found at diagnosis were severe headache (94%), visual deficits (97%), panhypopituitarism (76%), psychiatric disturbances (47%), and abnormal somnolence (47%). The highest rate of endocrine deficits occurred in patients younger than 19 years of age (p < 0.001), whereas hypothalamic disturbances were observed mainly in adults between 30 and 49 years (p = 0.02). Hydrocephalus was present in 63% of the patients, predominantly involving the younger subgroup (p < 0.001). Preoperative diagnosis was based on clinical signs, funduscopic exams, and skull radiographs, the latter study showing suprasellar calcifications in 64% of cases. The majority of tumors (61%) had developed within the third ventricle (3V) or had invaded it. The adamantinomatous histological variant was the predominant one (73%). Squamous-papillary CPs occurred only in adults older than 40 years of age (p < 0.001). Strong CP adherences to the hypothalamus were demonstrated in 63% of cases. The infundibulo-tuberal and sellar/suprasellar-3V CP topographies were associated with the highest rates of hypothalamic dysfunction before surgery (p < 0.001), surgical hypothalamic injury (p < 0.001), and severe postoperative morbidity and/or mortality (p = 0.009). Both topographies showed the strongest adherences to the hypothalamus and 3V (p < 0.001). CONCLUSIONS: Cushing's CP series comprises severely ill patients with tumors in the late stages of progression, with a high rate of tumors developing primarily within the hypothalamus (infundibulo-tuberal CPs) or invading this structure from the sellar/suprasellar regions. Craniopharyngioma topography was the fundamental variable influencing the clinical manifestations, tumor features, and patient outcomes in this series.

Ergotism is the long-term ergot poisoning by ingestion of rye or other grains infected with the fungus Claviceps purpurea and more recently by excessive intake of ergot drugs. It has either neuropsychiatric or vascular manifestations. In the Middle Ages, the gangrenous poisoning was known as St. Anthony's fire, after the order of the Monks of St. Anthony who were particularly skilled at treating the condition. In 1917, Prof. Arthur Stoll returned home to Switzerland from Germany, to lead the development of a new pharmaceutical department at Sandoz Chemical Company. Stoll, using the special methods of extraction learned from his work with his mentor Willstetter, started his industrial research work with ergot. He succeeded in isolating, from the ergot of rye, ergotamine as an active principle of an old popular remedy for excessive post-partum bleeding. The success of this discovery occurred in 1918 and was translated into a pharmaceutical product in 1921 under the trade name Gynergen. In subsequent work, Stoll and his team were leaders in identifying the structure of the many other alkaloids and amines produced by Claviceps purpurea This was the cultural background and scientific foundation on which bromocriptine was discovered.

The field of pituitary surgery was born in the first decade of the twentieth century in Europe, and it evolved rapidly with the development of numerous innovative surgical techniques by some of the founding fathers of neurosurgery. This study investigates the pioneering Italian treatise on pituitary surgery, La Patologia Chirurgica dell'Ipofisi (Surgical Pathology of the Hypophysis), published in 1911 by Giovanni Verga (1879-1923), a surgeon from Pavía and one of Golgi's disciples. This little-known monograph compiles the earliest experience on pituitary surgery through the analysis of the first 50 procedures performed between 1903 and 1911. We conducted a biographical survey of Giovanni Verga and the motivations for his work on pituitary surgery. In addition, a systematic analysis of all original reports and historical documents about these pituitary procedures referenced in Verga's treatise was carried out. Verga's treatise provides a summary of the techniques employed and surgical outcomes for the first 50 attempted procedures of pituitary tumor removal. This monograph is the only scientific source that includes a complete account of the series of 10 pituitary tumors operated on by Sir Victor Horsley in the 1900s. Three major types of surgery were employed: (i) palliative procedures of craniectomy (n = 6); (ii) transcranial approaches to the pituitary gland, either subfrontal or subtemporal (n = 13); and (iii) transphenoidal routes to expose the sella turcica, either using an upper transnasal-transethmoidal approach (n = 19) or a lower sublabial/endonasal-transeptal one (n = 12). An operative mortality rate of 36% (n = 17) was observed in these early series. The pathological nature of the tumors operated on was available in 42 cases. There were 28 adenomas and 15 craniopharyngiomas. Sir Victor Horsley (1857-1916) and the Viennese surgeons Anton von Eiselsberg (1860-1939) and Oskar Hirsch (1877-1965) were the leading European figures in the development of pituitary surgery. Giovanni Verga's treatise La Patologia Chirurgica dell'Ipofisi is a fundamental, pioneering book in the history of pituitary surgery, a work that compiles the foundations of this field in Europe and the only authoritative source providing a complete record of pituitary procedures performed by Sir Victor Horsley.

OBJECTIVE: To determine the frequency of central nervous system (CNS) tumors in the first fifty years of the National Institute of Neurology and Neurosurgery of Mexico Manuel Velasco Suárez (Instituto Nacional de Neurología y Neurocirugía de México, INNN) from 1965 to 2014. MATERIALS AND METHODS: A total of 16 116 institutional records of CNS tumors were analyzed. The frequency and distribution of CNS tumors were evaluated by tumor type, patient age and patient gender. The annual relationship between CNS tumors and surgical discharges (SD) over the last 20 years was estimated. RESULTS: The frequencies of most CNS tumors were consistent with those found worldwide, and the most common tumors were neuroepithelial tumors (33%), particularly astrocytic tumors (67%); meningeal tumors (26%); and pituitary tumors (20%). The incidence of pituitary tumors in these data was twice as high as that reported in other regions of the world, and the relationship between CNS tumors and SD was consistent over time (0.22-0.39). CONCLUSION: This study summarizes the largest sample of CNS tumor cases analyzed in Mexico and provides an important reference of the frequency of this tumor type in the country. This work will serve as a basis for conducting studies evaluating factors associated with the presence of CNS tumors and for identifying adequate public health interventions.

From the very beginning of his career, Harvey Williams Cushing (1869-1939) harbored a deep interest in a complex group of neoplasms that usually developed at the infundibulum. These were initially known as "interpeduncular" or "suprasellar" cysts. Cushing introduced the term "craniopharyngioma" for these lesions, which he believed represented one of the most baffling problems faced by neurosurgeons. The patient who most influenced Cushing's thinking was a 16-year-old seamstress named "Mary D.," whom he attended in December 1901, exactly the same month that Alfred Fröhlich published his seminal article describing an adiposogenital syndrome in a young boy with a pituitary cyst. Both Cushing's and Fröhlich's patients showed similar symptoms caused by the same type of tumor. Notably, Cushing and Fröhlich had met one another and became good friends in Liverpool the summer before these events took place. Their fortunate relationship led Cushing to realize that Fröhlich's syndrome represented a state of hypopituitarism and provided a useful method of diagnosing interpeduncular cysts. It is noteworthy that Cushing's very first neurosurgical procedure on a pituitary tumor was performed in the case of Mary D.'s "interpeduncular cyst," on February 21, 1902. Cushing failed to remove this lesion, which was later found during the patient's autopsy. This case was documented as Pituitary Case Number 3 in Cushing's masterpiece, The Pituitary Body and Its Disorders, published in 1912. This tumor was considered "a teratoma"; however, multiple sources of evidence suggest that this lesion actually corresponded to an adamantinomatous craniopharyngioma. Unfortunately, the pathological specimens of this lesion were misplaced, and this prompted Cushing's decision to retain all specimens and documents of the cases he would operate on throughout his career. Accordingly, Mary D.'s case crystallized the genesis of the Cushing Brain Tumor Registry, one of Cushing's major legacies to neurosurgery. In this paper the authors analyze the case of Mary D. and the great influence it had on Cushing's conceptions of the pituitary gland and its afflictions, and on the history of pituitary surgery.

Pituitary adenomas are among the most common central nervous system tumors. They represent a diverse group of neoplasms that may or may not secrete hormones based on their cell of origin. Epidemiologic studies have documented the incidence of pituitary adenomas within the general population to be as high as 16.7%. A growing body of work has helped to elucidate the pathogenesis of these tumors. Each subtype has been shown to demonstrate unique cellular changes potentially leading to tumorigenesis. Surgical advancements over several decades have included microsurgery and the employment of the endoscope for surgical resection. These advancements increase the likelihood of gross-total resection and have resulted in decreased patient morbidity.

Sir Victor Horsley (1857-1916) is considered to be the pioneer of pituitary surgery. He is known to have performed the first surgical operation on the pituitary gland in 1889, and in 1906 he stated that he had operated on 10 patients with pituitary tumors. He did not publish the details of these procedures nor did he provide evidence of the pathology of the pituitary lesions operated on. Four of the patients underwent surgery at the National Hospital for Neurology and Neurosurgery (Queen Square, London), and the records of those cases were recently retrieved and analyzed by members of the hospital staff. The remaining cases corresponded to private operations whose records were presumably kept in Horsley's personal notebooks, most of which have been lost. In this paper, the authors have investigated the only scientific monograph providing a complete account of the pituitary surgeries that Horsley performed in his private practice, La Patologia Chirurgica dell'Ipofisi (Surgical Pathology of the Hypophysis), written in 1911 by Giovanni Verga, Italian assistant professor of anatomy at the University of Pavia. They have traced the life and work of this little-known physician who contributed to the preservation of Horsley's legacy in pituitary surgery. Within Verga's pituitary treatise, a full transcription of Horsley's notes is provided for 10 pituitary cases, including the patients' clinical symptoms, surgical techniques employed, intraoperative findings, and the outcome of surgery. The descriptions of the topographical and macroscopic features of two of the lesions correspond unmistakably to the features of craniopharyngiomas, one of the squamous-papillary type and one of the adamantinomatous type. The former lesion was found on necropsy after the patient's sudden death following a temporal osteoplastic craniectomy. Surgical removal of the lesion in the latter case, with the assumed nature of an adamantinomatous craniopharyngioma, was successful. According to the evidence provided in Giovanni Verga's monograph, it can be claimed that Sir Victor Horsley was not only the pioneer of pituitary gland surgery but also the pioneer of craniopharyngioma surgery.

RESULTS: of morphological and tomographic (CT) studies of the skull that was found in the crypt of the Silesian Piasts in the St. Jadwiga church in Brzeg (Silesia, Poland) are presented and discussed here. The established date of burial of probably a 20-30 years old male was 16th-17th century. The analyzed skull showed premature obliteration of the major skull sutures. It resulted in the braincase deformation, similar to the forms found in oxycephaly and microcephaly. Tomographic analysis revealed gross pathology. Signs of increased intracranial pressure, basilar invagination and hypoplasia of the occipital bone were observed. Those results suggested the occurrence of the very rare Arnold-Chiari syndrome. Lesions found in the sella turcica indicated the development of pituitary macroadenoma, which resulted in the occurrence of discreet features of acromegaly in the facial bones. The studied skull was characterized by a significantly smaller size of the neurocranium (horizontal circumference 471 mm, cranial capacity â¼ 1080 ml) and strongly expressed brachycephaly (cranial index=86.3), while its height remained within the range for non-deformed skulls. A narrow face, high eye-sockets and prognathism were also observed. Signs of alveolar process hypertrophy with rotation and displacement of the teeth were noted. The skull showed significant morphological differences compared to both normal and other pathological skulls such as those with pituitary gigantism, scaphocephaly and microcephaly.
