Adult Laryngeal Ossified Hemangioma: Difficulties in Differential Diagnosis

Adult laryngeal hemangiomas are uncommon and often poorly symptomatic. The authors describe a laryngeal hemangioma with acute airway obstruction and radiologic findings suggesting a chondrosarcoma-like neoplasm, while pathologic features were consistent with an ossified hemangioma. The presence of fields of bone metaplasia into a classical cavernous hemangioma is an unusual phenomenon which, to our knowledge, was never previously described in the larynx. Difficulties concerning the differential diagnosis and modality of treatment are also discussed.

The objective of the study was to examine the utility of O-arm navigation-assisted surgery for a primary spine tumor. A prospective study was performed in 18 consecutive patients who underwent O-arm navigation-assisted surgery for a primary spine tumor at our hospital between 2014 and 2017. Data were collected for patient demographics, tumor details, surgery performed, and postoperative complications. The proportion of patients with a primary spine tumor; complications in the navigation procedure and equipment; complications in resection; local recurrence; radiological evidence of mechanical failure in cases where implants...

Conclusions: Our findings reassure that malignant transformation of enchodromatosis of the hand is unlikely in the pediatric population. Pathologic fracture is common, but has excellent outcomes. When considering surgery, parents should be counseled about the possibility of phalangeal growth arrest and recurrence of the lesion. Type of Study/Level of Evidence: Level IV—therapeutic.

This report describes the case of 21  years-old male complain of right sided nasal obstruction for 10 months, and right sided aural fullness. Examination revealed multiple asymptomatic nodules in both hands since childhood, that have not been investigated and a large nasopharyngeal mass. Computed tomography, showed a 36 mm in 30 mm diameter lesion extending from the inferior aspect of the clivus and basisphenoid into the nasopharynx, which did not seems to be highly vascular with angiogram. Incidental radiological findings of multiple bubbly lytic bony lesions. Endoscopic sinus surgery and clival lesion...

Biopsy of the lesions is technically difficult owing to their complex anatomy. The Differential Diagnosis (DD) includes a wide array of lesions including Simple Bone Cyst, Ameloblastoma, Central Giant Cell Granuloma, Hemangioma, Osteoblastoma, Osteochondroma, Chondroblastoma, Chondrosarcoma, Neurofibroma and metastatic malignant lesions...

Abstract Maffucci syndrome is a nonhereditary disorder caused by somatic mosaic isocitrate dehydrogenase 1 or 2 (IDH1 or IDH2) mutations and is characterized by multiple enchondromas along with hemangiomas. Malignant transformation of enchondromas to chondrosarcomas and secondary neoplasms, such as brain tumors or acute myeloid leukemia, are serious complications. A 15‐year‐old female with Maffucci syndrome developed B‐cell precursor acute lymphoblastic leukemia (BCP‐ALL). A somatic mutation in IDH1 was detected in hemangioma and leukemic cells. KRAS mutation and deletion of IKZF1 were detected in leukemic cells. P...

MA Abstract BACKGROUND: Increasing numbers of conventional X‑rays, computed tomography and magnetic resonance imaging in the inpatient, outpatient and scientific routine leads to an increasing number of incidental findings. The correct interpretation of these incidental findings with respect to the relevance and the evaluation concerning further work-up is an important task of radiologists. OBJECTIVE: Description of common incidental findings in musculoskeletal imaging and their clinical classification. MATERIAL AND METHODS: A PubMed literature search was performed using the following terms: inci...

CONCLUSIONS Endonasal endoscopic approaches can play a role in the management of nonmeningeal, nonadenomatous tumors invading the CS, either through biopsy, debulking, or GTR. An advantage of this method is the relief of preexisting cranial neuropathies with low risk for new neurological deficit. Extent of resection within the CS varies with KS grade and degree of carotid encasement irrespective of the underlying pathology. The goals of surgery should be clearly established preoperatively in consultation with radiation and medical oncologists. PMID: 27128582 [PubMed - as supplied by publisher]

The infrapatellar fat pad (IFP) also known as Hoffa fat pad, an intracapsular extrasynovial structure readily visualized on magnetic resonance imaging of the knee,1 can be affected by a variety of pathologic conditions (lipoma, hemangioma, synovial chondromatosis, focal villonodular synovitis, ganglion cyst, osteochondroma, and chondrosarcoma).2 Because synovial hemangioma is an extremely rare disease and often shows nonspecific symptoms (pain, swelling, limping, or limitation of motion), diagnosis could be delayed in many cases.

This article shows the radiologic manifestations of the principal primary bone tumors of the spine from a practical point of view, based on our personal experience and a review of the literature. If bone metastases, multiple myeloma, lymphomas, hemangiomas, and enostoses are excluded, only eight types of tumors account for 80% of all vertebral tumors. These are chordomas, osteoblastomas, chondrosarcomas, giant-cell tumors, osteoid osteomas, Ewing's sarcomas, osteosarcomas, and aneurysmal bone cysts.
