“…Total surgical removal is considered to be the only effective treatment for osteochondroma, 3,[12][13][14][15]19,21,26) but the present tumor adhered tightly to the pituitary stalk, making total removal impossible. We found that partial removal relieved the compression of the optic chiasm and nerve.…”

A 29-year-old man presented with a primary sellar turcica osteochondroma manifesting as intratumoral hemorrhage mimicking pituitary apoplexy. The patient suffered sudden onset of headache concomitant with vision loss in the left eye. Radiography and computed tomography detected destruction and calcification of the sellar turcica. Magnetic resonance imaging revealed a heterogeneously enhanced suprasellar mass that had elevated and compressed the optic chiasm. The preoperative diagnosis was hemorrhagic pituitary adenoma, craniopharyngioma, meningioma, or chordoma based on the signal heterogeneity of the lesion. To relieve the symptoms and make a definitive diagnosis, surgical removal via a basal interhemispheric approach was carried out. The tumor was not totally removed because of tight adhesion to the pituitary stalk, but postoperative ophthalmological examination revealed improvement of the visual disturbance. The histological diagnosis was osteochondroma based on the presence of mature chondrocytes and osteomatous tissue. Osteochondroma should be included in the differential diagnosis of tumors with acute hemorrhage in the sella turcica.

“…Osteocartilaginous tumors are exceedingly rare, are usually dural‐based, develop in the skull and only secondarily displace dura and brain . To our knowledge, extraosseous osteoma, chondroma, osteochondroma, mesenchymal chondrosarcoma, osteosarcoma and aneurysmal bone cyst have been seldom described in the CNS. A few cases of unusual dura‐based periosteal osteoblastoma have also been reported in cranial bones, such as temporal bone and frontal cranial bone .…”

Intraspinal dural‐based primary osteoblastoma with aneurysmal bone cyst‐like change

Osteoblastoma is a benign bone-forming neoplasm that occurs commonly in the posterior elements of the spine and the sacrum. However, so far there has been no report of intradural osteoblastoma described in the literature. We present a unique case of intraspinal dural-based osteoblastoma with aneurysmal bone cyst-like change without evidence of vertebral involvement. An 11-year-old Chinese girl presented with a 3-month history of gradually progressive back pain and a weakness of both lower limbs. Thoracic MRI revealed a well-demarcated subdural mass at the T5 level with heterogeneous enhancement. Histologically, the tumor was found to be attached to the dura and composed of numerous osteoid spicules and trabecular bone with diffusely scattered osteoclast-type, multinucleated giant cells. Ectactic blood vessels and blood-filled cystic spaces were also observed. A diagnosis of primary intraspinal dural-based osteoblastoma with aneurysmal bone cyst-like change was made. To our best knowledge, this is possibly the first case of primary osteoblastoma arising from meninges. Meningeal osteocartilaginous tumors are rare, with obscure histogenesis. The differential diagnosis of osteoblastoma in unusual locations is difficult and the confirmation of diagnosis should be cautiously made. Awareness of dural-based osteoblastoma and its histological features is important to avoid a diagnostic pitfall caused by histological similarities to other intra-craniospinal lesions with osteoid differentiation or bone formation.

“…3 It arises infrequently in the cranial cavity, presenting as calcified foci and accounts for < 1% of all intracranial space-occupying lesions. 4 Most OCs originating from the skull base are from the middle fossa, where the cranial sutures converge. Hence OCs are thought to arise from the cartilaginous rests in the basilar synchondroses.…”

Osteochondroma (OC) is the most common benign bone neoplasm. It infrequently occurs in the cranial cavity as a calcified lesion and very rarely presents in the sellar region. The present study summarizes the knowledge about OCs of the sellar region. We searched the literature search for the clinical appearance of OCs and other calcified pathologies occurring in the sellar region. A total of 21 English-language articles published from 1961 to 2015 documented cases of calcified lesions in the sellar region including cerebral aneurysm, chondroid chordoma, chondroma, craniopharyngioma, OC, odontome, osteoma, pituitary adenoma, pituitary stone, Rathke cleft cyst, retinoblastoma, schwannoma, and xanthogranuloma. Among them, six were OC cases: three in the parasellar region and three in the sellar-suprasellar region. Patients with sellar-suprasellar OCs presented with visual loss and hypopituitarism; patients with parasellar OCs did not show these symptoms. OCs appeared as irregular and multilobulated calcifications on X-ray and computed tomography. On magnetic resonance imaging, OCs showed variable intensity on T1-weighted sequences and consistently heterogenous intensity on T2. Four patients underwent transcranial tumor resection, and the transsphenoidal route was selected for one. Five of the six resulted in a partial resection or internal decompression with a satisfactory outcome. Calcified tumors occurring in the sellar region may be OCs, especially if they appear as irregular multilobulated calcification.
