Capillary hemangioma of the sphenoid sinus with intrasellar and parasellar extensions

Adult transverse sinus capillary hemangioma: case report and review of the literature

BACKGROUND

Adult intracranial capillary hemangioma (ICH) is an extremely rare disease with very few cases reported in the literature. Natural history is poorly understood and therapeutic management has not been clearly defined.

METHODS

Using PRISMA guidelines, we systematically reviewed all published adult cases of ICH, to which we added our own case.

CASE PRESENTATION

A 24-year-old patient with intracranial hypertension underwent stenting for left transverse sinus ICH. Recurrence was managed by subtotal resection, and radiotherapy was undertaken after a second relapse. Radiotherapy achieved complete response at last follow-up.

RESULTS

Among cases of ICH found in the literature, 36 concerned adults (55.3%), with clear female predominance, and only 2 cases affecting the transverse sinus (8.1%). Adult ICHs grew over time, and pregnancy seemed to accelerate natural progression. Complete resection was achieved in most cases, and radiotherapy was used in case of relapse, with high rates of tumor control.

CONCLUSION

Transverse sinus ICH is uncommon, and venous stenting is a suitable option in case of tumor invasion to treat intracranial hypertension. Surgery is the gold-standard treatment, and radiotherapy is a very effective alternative, with high rates of tumor control. Natural history is not benign, particularly in case of pregnancy.

A Rare Case of Sphenoid Sinus Hemangioma With Intrasellar and Cavernous Sinus Extension

Sphenoid sinus hemangiomas are uncommon and pose significant diagnostic challenges due to their rarity and the complex symptoms associated with their critical anatomical location. This report discusses a woman in her 40s who presented with worsening headaches, diplopia, and a sensation of pressure behind her eyes. Diagnostic imaging revealed a lobulated mass in the sphenoid sinus extending into the cavernous sinus and sella, initially mimicking an aggressive neoplastic pathology. However, histopathological examination following endovascular embolization and partial surgical resection confirmed the diagnosis of a cavernous hemangioma. This case highlights the importance of considering hemangiomas in the differential diagnosis of sphenoid sinus masses, especially when patients present with atypical symptoms and imaging shows features such as high vascularity and bone remodeling. The findings emphasize the need for careful diagnostic and therapeutic approaches to effectively manage such cases and differentiate them from more aggressive pathologies.

Cavernous Sinus capillary hemangioma: Case report and literature review

Introduction

Capillary hemangioma of the cavernous sinus is considered a benign vascular skull base tumor. In this case report, a patient with capillary hemangioma located in the cavernous sinus who was operated on with endoscopic endonasal approach is presented.

Research question

What should be considered when planning the treatment for capillary hemangiomas located in the cavernous sinus?

Material and methods

The treatment approaches applied in 12 patients with a diagnosis of capillary hemangioma located in the cavernous sinus, reported in the English literature, are reviewed in this article. We presented the clinical and radiological results of the treatments.

Results

Cavernous sinus capillary hemangiomas are considered benign tumors. However, surgical treatment is preferred in the foreground because of the neurological deficits due to the compression effect caused by the mass. In the case reported by Masman et al. for the first time in the literature in 2021, they provided total excision with the endoscopic endonasal approach in the patient they first diagnosed by taking a biopsy with the endoscopic endonasal approach. In our case report, we provided total excision with endoscopic endonasal transsphenoidal approach.

Discussion and conclusion

Many factors should be considered when deciding on the treatment method in these patients. Although radiotherapy is quite effective in the treatment of capillary hemangioma, surgery should be preferred, especially in symptomatic patients. In patients who cannot undergo surgery, radiotherapy is very valuable, although the long-term results are not yet known.

Management of Capillary Hemangioma of the Sphenoid Sinus

Background and objectives: Capillary hemangiomas are rare, benign vascular tumors that mainly affect the skin and soft tissue, with scarce appearance within the nasal cavities and paranasal sinuses. Materials and methods: We present a case report of capillary hemangioma of the sphenoid sinus and a review of the literature in the last ten years. Results: Clinical and endoscopic examination of the nose, radiologic assessment and particular histologic features contribute to the correct diagnosis of capillary hemangioma of the nose and paranasal sinuses. Conclusions: Transnasal endoscopic resection of capillary hemangioma located in the nose and paranasal sinuses is a valuable treatment method with good outcomes.

Case of a Pregnant Woman with Capillary Hemangioma of the Parasellar Region

Here we report a rare case of capillary hemangioma (CH) in a 28-year-old woman suffering from gradual worsening diplopia at 28 weeks of pregnancy. Magnetic resonance imaging (MRI) showed a mass lesion (about 3 cm in diameter) in the right parasellar region. We decided to observe as she was pregnant, and had no symptoms other than right abducent nerve palsy. Fortunately, her symptoms did not worsen until delivery. Computed tomography, enhanced MRI, and angiography after delivery revealed that the lesion was highly calcified and vascularized. A dorsum sellae meningioma or highly calcified pituitary adenoma was suspected and the endoscopic transsphenoidal approach was used for tumor removal.

The postoperative course was uneventful. The histological diagnosis was CH.

Intracranial CHs or CHs of skull are rare vascular tumors. These tumors are reportedly more common in female patients and may change in size in adults according to menstrual cycle and pregnancy. Only six cases, including that of the present study, were diagnosed during the perinatal period. Some of them experienced rapid symptom progression and tumor growth in their course; thus, we should pay further attention to pregnant or peripartum patients with brain tumor, suspected hemangiomas.
