Chordomas located primarily in the sellar region are uncommon, and may be misdiagnosed non-functioning pituitary adenoma. Furthermore, the association of a persistent primitive trigeminal artery (PPTA) with an intrasellar chordoma is extremely rare, and no similar cases have been reported in the literature to date. The coexistence of intrasellar chordoma (ISC) and PPTA makes safe and complete t...

We present CT scan, MRI and histopathologic findings of two patients harboring a rare type of meningioma. In the first case, a 52 year-old male patient, a large parasellar mass invading the cavernous sinus, infiltrating the infratemporal fossa and extending as low as C2 was founded. The tumor was isointense on T1, enhanced strongly with gadolinium injection, and was hyperintense on T2. In the s...

Chordomas of the tip of the tail in 6 ferrets were examined using histopathological, histochemical and immunohistochemical procedures. Histopathologically, round neoplastic cells containing numerous cytoplasmic vacuoles of varying sizes, categorized as "physaliphorous cells", were observed in the amorphous eosinophilic or pale basophilic myxoid stroma. Physaliphorous cells were arranged in lobu...

Background: Skull base chordoma is a rare tumor with slow and progressive growth. Significance of this tumor is it’s difficult to access location in skull base. This is the reason for various proposed techniques for resection of the tumor. Endoscopic endonasal technique is a minimally invasive approach that gives surgeons opportunity of total resection of tumor and low morbidity. Total resectio...

Chondroid chordoma commonly presents as clival osseous and extradural mass. A 15-year-old boy presented with progressive visual deficit, headaches and diplopia since three years. Computed tomography (CT scan) showed a skull base tumour, but was wrongly reported at the time as chronic sphenoidal sinusitis and nasal polyps. In the past three months, he developed dysphagia, urinary retention and c...

Treatment results of 17 patients who were diagnosed with sacral chordoma between 1993 and 2007, were analyzed retrospectively. The mean duration of symptoms was 30.2 months. The mean tumour size was 10.7 cm; the location was S2 or more proximal in ten-patients. A wide resection was achieved in 14 patients, a marginal resection in one patient and two patients had intralesional excision. Seven pa...

Sacral chordoma presents a difficult diagnostic and therapeutic problem, with diffucult differantion of malign and bening lesion. An 66year-old male, presented with a history of back-lower extremity pain and leg weakness. MRI demonstrated a mass, which measured 10x10x15 cm, was located in front of the sacrum so as to compress the rectum forward. The patient was referred to our positron emission...
