OBJECTIVE
To report the first case of an ectopic adrenocorticotropic hormone (ACTH) syndrome caused by a sacrococcygeal chordoma.
METHODS
We present a case report with clinical, laboratory, and histologic details.
RESULTS
A 76-year-old man was admitted to the hospital because of urinary obstruction.
A 29-year-old man presented with headache, confusion, word-finding difficulty, and a visual field deficit 16 months after complete removal of a sacrococcygeal chordoma. Magnetic resonance imaging of the head demonstrated two discrete enhancing left occipital lesions with associated cerebral edema.
This "syndrome" has been observed in 4 of 23,935 in-patients registered in the years 1974-1987 in the Comprehensive Hospital Drug Monitoring (Bern/St. Gallen), with 6 reactions. Signs of an attack of bronchial asthma, laryngeal or pulmonary edema or a (heart-)circulatory event were not observed.
The starting-point of the presented retrospective, clinical study is the observation, that in some cases a delayed postoperative neurological deterioration develops after removal of great, extraparenchymal, infratentorial brain tumors. Therefore, we evaluated the postoperative clinical course of 50
Intracranial chondromas are rare benign tumors. Little data are available on the diagnosis and treatment of these tumors. Thus, we aimed to describe a large series of patients with intracranial chondroma and to analyze and discuss the clinical features and microsurgical treatment of these patients.
OBJECTIVE
The purpose of this paper is to evaluate acute radiation-induced toxicity of carbon ion therapy.
METHODS
From December 1997 to November 2000, 37 patients with chordomas and low-grade chondrosarcomas of the skull base have been treated with carbon ions at the heavy ion synchrotron (SIS) at
The authors analyse the results of clinico-CT studies in complicated course of the early postoperative period in 104 patients (87 adults and 17 children) with tumors of the posterior cranial fossa (PCF). According to the histological structure and predominant topography of the neoplasm, the cases
A 21-year old woman underwent surgery in December 1996 for the removal of a presumed tuberculum sellae meningioma. However, some radio-clinical findings were proved somewhat intriguing:the patient's age, the presence of inflammatory and febrile syndromes together with the diagnosis of aseptic
Midfacial degloving can be characterized as an alternative surgical approach for exposing the bony structures of the midface. In combination with transient partial osteotomies the nasal cavities, the paranasal sinuses, the pterygopalatine fossa and the posterior parts of the anterior skull base are
BACKGROUND
The venous drainage of the temporal lobe, through bridging veins to the middle cranial fossa, is pivotal in determining the surgical corridor for skull base lesions. In dealing with select cases, where venous drainage was an obstacle in the surgical approach, we hypothesized that staged
OBJECTIVE
Foramen magnum tumors, especially those located ventrally, are surgically challenging. We studied clinical and surgical details of extramedullary tumors located in the region of the foramen magnum.
METHODS
A series of 30 cases of extramedullary tumors at the foramen magnum, operated over a
Chordoid meningioma is a rare variant of meningioma with histological features resembling those of chordoma. This tumour should have a greater risk of recurrence and aggressive growth (WHO grade II). So far, 92 such tumours have been described in the literature. We report two cases of chordoid
Bone xanthoma is an extremely rare and benign tumor in terms of its nature and growth over time. We describe the first case coexisting with ventriculomegaly secondary to aqueduct stenosis (non-tumoral hydrocephalus), the second xanthoma of the clivus described to date. The patient was a 51-year-old
A case of chordoid meningioma occurring in a 15-year-old girl is presented. The patient manifested seizures as the initial symptom and subsequently exhibited subclinical microcytic hypochromic anemia. The tumor, located in the falcotentorial region and associated with diffuse edema, was totally
The transoral-transpharyngeal approach is a reliable and technically sound method for gaining anterior extradural exposure to the craniocervical junction. We report 23 patients undergoing this approach for pathology lying between the inferior clivus and third cervical vertebra. Pathology included 6
