Orbital cavernous hemangioma in an infant with intracranial lesions: a case report

Isolated cavernous venous malformation of the eyelid

Cavernous hemangioma, currently known as "cavernous venous malformation," is a common, benign, non-infiltrative, slowly progressive vascular malformation of the orbit presenting in adults. We report the case of a 9-year-old girl who presented with a painless palpable mass over the right upper eyelid of 7 years' duration. A computed tomography scan of the orbits revealed a heterogeneously enhancing, well-circumscribed mass in the right upper eyelid with no orbital extension. A transcutaneous excisional biopsy with histopathology disclosed cavernous venous malformation. The majority of cavernous venous malformations are intraconal and present in the fourth to fifth decade of life.

Surgical Intervention in Pediatric Orbital Hemangioma: A Case Report

Infantile hemangiomas are common vascular tumors in infancy, typically affecting the skin. However, intraconal orbital hemangiomas are rare and present diagnostic challenges due to their impact on critical structures within the orbit. We present the case of a 1-year-old male with progressive orbital swelling and proptosis. Initial conservative management with propranolol was attempted, but due to the lack of response, surgical resection of the intraconal hemangioma was performed. Pediatric orbital hemangiomas, particularly intraconal variants, pose distinctive diagnostic challenges. While conservative approaches, such as propranolol, align with evolving strategies for infantile hemangiomas, surgical intervention may be necessary in cases with an inadequate response. This case underscores the importance of recognizing the need for timely surgical intervention in pediatric orbital hemangiomas, even after initial conservative measures. Successful surgical outcomes contribute to understanding pediatric orbital pathology and emphasize the ongoing evolution of management strategies in this challenging clinical scenario.

Cavernous Hemangioma in the Orbital Cavity: Case Report

Cavernous hemangiomas are benign malformations of vascular origin, usually well circumscribed and slow to grow. These lesions can be asymptomatic, being discovered unintentionally in imaging exams or symptomatic, indicated mainly by the presence of proptosis, diplopia, and visual disturbances by optic nerve compression. The complementary exams involve computed tomography associated with contrast, color Doppler, magnetic resonance, and angiography. Treatment can be conservative or surgical depending on the case, and the open therapy usually involves lateral, supraorbital, transconjunctival, transantral, pterional, transnasal, and extradural endoscopic orbitotomy. The present study aimed to report a recurrent case of hemangioma in the orbital cavity signaled by ocular proptosis, hyperemia, and ocular pain.The lesion was achieved through the Weber-Ferguson access with zygomatic osteotomy and preservation of the infraorbital nerve. The excision of the lesion was performed, and the previously displaced fragments were fixed with 1.5 mm mini plates. The patient has a chance of progressing with visual impairment due to considerable manipulation of the optic nerve and is being followed up.The reported case showed a successful diagnosis and therapeutic conduct, remaining now in the evolution and follow-up scenario.

Spontaneous regression of multiple intracranial capillary hemangiomas in a newborn-long-term follow-up and literature review

BACKGROUND

Intracranial capillary hemangiomas (ICHs) have a natural history and behavior that is very different from intracranial cavernous malformations. The literature is not consistent as to the best management strategy for ICHs.

CASE DESCRIPTION

Our patient is a 40-day-old male infant who presented with progressive increase in head circumference and multiple cutaneous capillary and ICHs. Obstructive hydrocephalus necessitated urgent cerebrospinal fluid (CSF) diversion, but no other surgical intervention was pursued due to the high risk-to-benefit ratio. All intracranial lesions spontaneously regressed by 11 years of age, albeit at a slower speed than the cutaneous lesions, with no functional or cognitive sequelae. We conducted a comprehensive literature review and provided a summary of all reported ICH cases.

CONCLUSION

Asymptomatic patients with ICHs are best approached with close follow-up and serial imaging studies as the potential for spontaneous regression is relatively high. Patients with isolated lesions or unclear diagnoses may benefit from a stereotactic biopsy, and surgical resection should be reserved for symptomatic lesions only.

A new surgical technique for excision of orbital cavernous hemangioma: a 15-year experience

PURPOSE

To present a new surgical technique for excision of orbital cavernous hemangiomas (CHs).

METHODS

This retrospective case series study included patients with orbital CH who were operated from 2001 to 2016 at our referral center. Epidemiologic data, symptoms, signs, and images were reviewed from patients' files with at least one year of follow-up. Surgical results and complications were documented. We used the "index finger dissection" technique without grasping the tumor for release of adhesions and its removal.

RESULTS

We included 60 patients with orbital CH consisting of 36 (60%) female and 24 (40%) male patients with mean age of 40 ± 12.1 (range 9-66) years. The main complaint was proptosis with average size of 5.3 ± 2 millimeters. The surgical approach was lateral orbitotomy in 49 (81.7%) patients, medial transcutaneous in seven (11.7%) patients, inferior transconjunctival in three (5%) patients, and simultaneous lateral and medial orbitotomy in one (1.6%) patient. All tumors were removed intact; complications included ptosis in one subject, lower lid retraction in one case, and diplopia in two patients, all of which improved before 2 months. No optic nerve damage occurred.

CONCLUSION

The "index finger dissection" technique without grasping the tumor for excision of orbital CH, via any external approach to the tumor, is a safe technique with minimal complications.
