Frontal intraosseous cryptic hemangioma presenting with supraorbital neuralgia

Blood within the bone: orbital intraosseous venous malformation

PURPOSE

Description of clinical features, radiological characteristics, and management strategies in primary orbital intraosseous venous malformation (OIVM) with pertinent literature review.

METHODS

A retrospective analysis including clinical, radiologic, operative, and histopathological data of six cases of histopathologically proven OIVM was done. A comprehensive literature review was conducted using online databases and augmented with manual search to identify reported cases of OIVM.

RESULTS

Study data showed five females and one male in young to middle-age group, with an average age of 30 years (range: 20-48 years). Proptosis was noted in five cases (83.33%), and the duration of symptoms ranged from 6 months to 10 years. Frontal and zygomatic bones were most frequently affected and expansile bony lesion was the most common CT scan finding. Three patients underwent pre-operative embolization of feeders followed by en bloc excision of mass and surgical reconstruction (50%); one patient was managed with partial excision (16.66%) while two were regularly followed-up after incision biopsy (33.33%). Histopathology revealed vascular spaces with endothelial lining, separated by bony trabeculae in all patients. Follow-up periods ranged from 6 to 48 months and no recurrence or progression were noted.

CONCLUSIONS

OIVM is an exceptionally rare disorder with a gradually progressive benign course. Ophthalmologists need to be mindful of this entity during patient evaluation as it has propensity for large volume blood loss intra-operatively, owing to its vascular nature. Complete excision with reconstruction of resultant defect is the preferred treatment strategy and without known recurrence.

High risk of cerebrospinal fluid leakage in surgery of a rare primary intraosseous cavernous hemangioma of the clivus showing meningeal infiltration: A case report and review of the literature

BACKGROUND

Primary intraosseous cavernous hemangiomas (PICH) of the skull represent an infrequent bone tumor. Although some rare cases of PICHs located in the skull base have been published, to our concern only three cases have been reported in the English literature of PICHs arising within the clivus.

CASE DESCRIPTION

We present the case of a patient presenting an isolated abducens paresis due to a rare PICH of the clivus showing also an unusual destruction of the inner table as well as infiltration of the dura mater. Due to this uncommon infiltrative pattern of an otherwise expected intraosseous tumor, a cerebrospinal fluid (CSF)-fistula occurred while performing a transnasal biopsy. The patient recovered successfully without need of lumbar drainage or re-surgery. Additionally, intratumoral decompression was sufficient to relief the abducens paresis.

CONCLUSIONS

Our case provides new and meaningful information about clinical features as well as growth pattern of these rare clival tumors. We also discuss the importance of knowing these peculiarities before surgery in order to plan the optimal operative management as well as to avoid complications while approaching PICHs localized in such a delicate cranial region.

Posttraumatic skull hemangioma: case report

Intraosseous cavernous hemangiomas of the skull are rare lesions for which the origin is unclear. The authors present a case in which there was a radiologically documented history of trauma preceding the development of a hemangioma in the frontal bone. In a review of the literature the authors found 83 cases of skull hemangiomas, and 43% of the lesions were located in the frontal bone. In 25% of these lesions, previous trauma was reported anamnestically. The present case and radiological findings related to it suggest a causal relationship between trauma and the development of intraosseous hemangioma.

Posttraumatic headache: surgical management of supraorbital neuralgia

BACKGROUND

Supraorbital neuralgia is a distinct clinical entity that presents with episodic, often unilateral, long-lasting attacks of moderate to severe frontal pain. This may ensue following a traumatic or surgical insult to the supraorbital or supratrochlear nerve. Surgical management of these patients is only sporadically discussed in the available literature.

METHODS

The authors report a series of six consecutive patients undergoing surgical excision of the supraorbital and supratrochlear nerves on the affected side for refractory posttraumatic or postoperative supraorbital neuralgia. End-to-end nerve coaptation by means of a neural tube conduit was used to prevent future neuroma formation. Success was defined as a 50 percent or greater reduction of preoperative pain level.

RESULTS

Five of six patients demonstrated at least a 50 percent reduction in pain. Three patients experienced complete pain cessation postoperatively. There was one treatment failure. Pain was measured using a visual analogue pain scale. Preoperative average pain was 9.16 +/- 1.3 and postoperative average pain was 1.5 +/- 1.9, an improvement of 7.7 points or 84 percent (p = 0.03). Mean age of the patients was 42 years. Mean follow-up was 14 months. No surgical complications occurred.

CONCLUSION

Excision of the supraorbital and supratrochlear nerves with end-to-end coaptation of the proximal nerve stumps by means of a neural tube appears to be an effective treatment in selected patients with chronic, posttraumatic supraorbital neuralgia.

Primary Intraosseous Skull Base Cavernous Hemangioma: Case Report

Primary intraosseous cavernous hemangiomas (PICHs) of the skull base are extremely rare tumors. These lesions are most common in the frontal and parietal bones of the calvarium. The authors describe a 40-year-old female who presented with progressive headaches. Serial imaging revealed a contrast-enhancing intraosseous lesion of the lateral body of the sphenoid bone and the greater wing associated with encroachment of the inferior cavernous sinus and mild posterior displacement of the cavernous carotid artery. Follow-up imaging 9 years later revealed slow growth of the lesion. The patient underwent complete excision of the PICH through an extradural frontopolar approach. Pathological examination revealed an intraosseous cavernous hemangioma. PICHs of the skull base can mimic other more common skull base lesions and thus can be difficult to diagnose preoperatively. Diagnosis is usually made at surgery. The authors review the literature regarding the clinical presentation, radiological characteristics, pathological features, and surgical management of PICHs.
