Petrous Temporal Bone

AbstractSporadic case reports and the few published series of expanding lesions of the deep petrous temporal bone propose a variety of surgical approaches to ensure excision. All such surgery represents a compromise between exposure adequate for total removal and avoidance of further neurological deficit. Unfortunately pathology in the petrous apex evolves relatively silently and diagnosis is delayed. In many cases total excision is impossible. We present a series of patients presenting with advanced tumours of the deep petrous temporal bone in order to illustrate the spectrum of disease encountered, the limited role of surgery and the natural history of irresectable pathology in this remote and inaccessible area.

Background: Current knowledge on ischemic stroke in sarcoid patients stems from sporadic case reports. The mechanism is thought to be related to granulomatous involvement of brain vasculature. However, clinical, demographic, and radiographic features of sarcoid patients with ischemic stroke are lacking. If sarcoid patients are at higher risk for ischemic stroke event, we hypothesized that the risk factors for ischemic stroke and stroke subtype distribution would differ between sarcoid and non-sarcoid ischemic stroke patients. Methods: Cases of ischemic stroke were identified for the years 2005 and 2010 from the population-based Greater Cincinnati/Northern Kentucky Stroke Study (population 1.3 million). Ischemic stroke cases were physician study confirmed and patients with a history of sarcoid were identified through medical chart review. Clinical variables were compared between stroke patients with history of sarcoid and those with no prior sarcoid history. Results: A total of 4258 cases of ischemic stroke were identified; of them, only 18 had prior diagnosis of sarcoid (0.04%). Brain MRI showed diffusion restriction in 14 out of 15 (93%) MRIs performed in sarcoid patients. The table presents risk factor and subtype data on sarcoid patients compared with non-sarcoid patients. Conclusions: We identified only a few cases of prior sarcoid history in our two-year ascertainment of ischemic stroke patients in our population. In comparison with stroke patients with no prior history of sarcoid, the sarcoid patients tended to be of younger age at presentation, female, have a history of diabetes and hyperlipidemia, and more likely of African descent, perhaps related to the diagnosis of sarcoid itself. We were unable to detect differences in stroke subtype distributions between sarcoid and non-sarcoid ischemic stroke patients.

Hypertension presents an increase in blood pressure following the oral manifestations, such as gingival enlargement. A 42-year-old woman came to the General Sudirman University Dental and Oral Hospital complaining of enlarged front gums seven years ago. The patient had a history of hypertension and regularly consumed drugs, amlodipine 5 mg. Extraoral examination revealed no lymphadenopathy and no swelling of the head and neck area. Intraoral examination revealed a gingival enlargement involving the papilla to the gingival margin present on the entire upper and lower labial gingival surface. The patient's diagnosis was gingival enlargement caused by gingival enlargement due to the use of amlodipine. Gingival enlargement has been noted with long-term or high-dose amlodipine use. The mechanism of amlodipine in causing gingival enlargement is through the role of fibroblasts with abnormal susceptibility to the drug, resulting in increased levels of protein synthesis, especially collagen. The role of pro-inflammatory cytokines occurs through an increase in interleukin-1β (IL-1β) and IL-6 in the inflamed gingival tissue due to the gingival fibrogenic response to drugs. Therapies were DHE and scaling and root planning as phase I in periodontal treatment. Plaque elimination is vital to reduce gingival inflammation that may occur. Substitution of the drug amlodipine may be needed if there is no improvement. Based on case reports, hypertension patients who took amlodipine could have gingival enlargement. The therapy given was plaque elimination in the form of DHE and Scaling and regular check-ups with the dentist.

Background: The orbital region can be occupied by various lesions including both neoplastic or non-neoplastic. Schwannomas of the supraorbital nerve are very rare tumors. Case Report: A case of a 15 years-old female patient with a one year history of progressive proptosis and no visual symptoms is presented with. This patient underwent a combined surgery with total removal of the tumor. Discussion: Intraorbital schwannomas are usually associated with neurofibromatosis and different structures can originate these tumours, including peripheral and cranial nerves. The signs and symptoms usually follow a chronic process. Surgical treatment is necessary, with various reported surgical approaches. Conclusion: We report, to the best of our knowledge, the eleventh case of schwannoma of the supraorbital nerve, describing the main features of this pathology.

Angiomyolipoma (AML) is a benign mesenchymal tumor that is frequently found in the kidney and, rarely, in the liver. The natural history of hepatic AML has not been clarified, and, because of the similar patterns in imaging studies, such as ultrasonography, computed tomography, and magnetic resonance imaging, some of these tumors have been overdiagnosed as hepatocellular carcinoma in the past. With an increase in the number of case reports showing detailed imaging studies and immunohistochemical staining of the tumor with human melanoma black-45, the diagnostic accuracy is also increasing. In this paper, we focused on the role of noninvasive imaging studies and histological diagnosis showing distinctive characteristics of this tumor. In addition, because several reports have described tumor progression in terms of size, recurrence after surgical resection, metastasis to other organs, and portal thrombosis, we summarized these cases for the management and discussed the indications for the surgical treatment of this tumor.

We present the case of a 50-year-old female with a 1-year history of right-side facial numbness, as well as an electric shock-like sensation on the right-side of the face and tongue. She was previously diagnosed with vertigo and trigeminal neuralgia. MRI was obtained showing a large right cerebellopontine angle mass. A retrosigmoid approach was performed and total removal was achieved after dissection of tumor from brainstem and cranial nerves IV, V, VI, VII and VIII. Pathology confirmed the diagnosis of a meningioma (WHO Grade I). The patient was discharged neurologically intact on the third postoperative day free of complications.The video can be found here: http://youtu.be/-tR0FtMiUDg.

AbstractObjectives:To describe a unique presentation of a predominantly extracranial glomus faciale tumour. To discuss the role of imaging in the differential diagnosis and evaluation of a hypervascular parotid mass. To review the previous literature concerning the glomus faciale tumour.Case report:A 54-year-old woman presented with a six-month history of facial weakness, pain and a parotid mass. Ultrasound revealed a hypervascular parotid mass and pre-operative core biopsy suggested a paraganglioma. Computed tomography defined its deep extent and demonstrated involvement of the petrous temporal bone along the descending portion of the facial nerve canal with a pattern of permeative lucency. A tumour was surgically removed which arose from the facial nerve from the second genu to the proximal divisions within the parotid gland and histology confirmed a paraganglioma.Conclusions:A facial nerve glomus faciale tumour should be considered in the differential diagnosis of a hypervascular parotid mass and may present in a predominantly extracranial location. Computed tomography will prove helpful in such a case in order to limit the differential diagnosis and to define the extent of skull base involvement.

Colloid cysts are benign, thin walled spherical neoplasms, composed of a collagenous capsule, underlying epithelium that arises from brain’s epidermal embryonic remnants and a viscous centre. They are shown to approximate 0.5% of all intracranial tumours with no recorded evidence of the petrous temporal bone involvement. Colloid cyst of the petrous temporal bone often presents with clinical symptoms of headache, hearing loss, facial palsy and imbalance/vertigo. Which is diagnosed on radiological and histological findings. Histologically, they are lined by ciliated cuboidal to pseudo stratified columnar epithelium resting on an eosinophilic basement membrane. Imaging Techniques are helpful in early diagnosis and preventing further complications. Here we will be discussing about a 24-year-old female, a known case of petrous apex osseous haemangioma presenting with unstable gait and tingling sensation on one side of face leading to an incidental finding of a colloid cyst on petrous temporal bone through histological examination.
