Introduction Few nasal cavernous haemangiomas have been previously reported, only nasopharyngeal cavernous hemangiomas have been reported; both arise from the lateral wall of the nasopharynx. We reported the case of a 27-year-old woman who had repeated severe epistaxis and nasal obstruction of 6 months duration. Computed tomography showed a large vascular nasopharyngeal mass. Complete endoscopic removal of the mass that was found to arise from the posterior end of the nasal septum was achieved without complications. Histopathology showed a cavernous heamangioma. Epistaxis completely stopped throughout the 12-month follow-up. This is the first work to describe the management of nasopharyngeal cavernous heamangiomas originating from the posterior end of the nasal septum. Transnasal endoscopic approach permits adequate exposure of the lesion, control of bleeding, and complete hemangioma removal.

| Introduction|| |
Hemangioma is a benign vascular tumor that can be histopathologically categorized into the common capillary type, mixed types, and the less common cavernous type ,,. Although hemangiomas are common in the head and neck, they are rare in the nasal cavity and paranasal sinuses .
Few cavernous haemangiomas have been previously reported to arise from the nasal cavity, namely from the inferior turbinate , middle turbinate , middle meatus , and the vomer . Only two nasopharyngeal cavernous hemangiomas have been previously reported, both arise from the lateral wall of the nasopharynx ,.
To the best of our knowledge, nasopharyngeal cavernous haemangiomas (CAs) that originate from the posterior end of the nasal septum has not been previously reported in the literature. Thus, this study aimed to describe hemangioma with such new origin in detail of its diagnosis and treatment.
| Case report|| |
A 27-year-old woman presented with a history of recurrent and conspicuous left-sided epistaxis and bilateral nasal obstruction of 6 months duration. Repeated anterior nasal packing and cauterization of the anterior septum were done elsewhere failed to control the epistaxis. The hemoglobin concentration was 7.8 g at presentation with normal coagulation profile. Endoscopic nasal examination was difficult and not informative as blood clots, crusts, and active bleeding obscured the view.
Contrast-enhanced computed tomography (CT) showed a heterogeneous well-defined large soft tissue density nasopharyngeal mass completely filling the nasopharynx with areas of calcification ([Figure 1] and [Figure 2]). The exact origin of the mass could not be identified because of its large size.

Diagnostic angiography showed leakage of the contrast media of both sphenopalatine arteries but no embolization was done.
After informed written consent was obtained, surgical intervention was undertaken under general hypotensive anesthesia. Transnasal endoscopic sinus surgery was used.
After suction of blood clots, a reddish highly vascular mass, bleeding extensively on touch completely filling the nasopharynx was found. A septal origin of the mass was proposed as it could not be pushed posteriorly. Endoscopic cauterization of the left sphenopalatine artery was achieved after raising a flap through a widened middle meatal antrostomy. This resulted in partial but not complete decrease in the amount of bleeding from the mass. Surface bipolar cauterization of the mass was tried but did not control the bleeding. A right-sided posterior septal incision was done 1 cm anterior to the mass. Septal flap was elevated and submucosal removal of the bone was done till the mass was reached. Bipolar cauterization of the posterior septum submucosally resulted in devascularization of the mass and stoppage of bleeding. The mass was separated completely and removed through the oral cavity. The posterior end of the septum was cauterized and removed by the backbiter. After removal of the mass, there was no bleeding and no packs were used. The patient was discharged on the second postoperative day and was prescribed saline nasal irrigation.
Histopathological examination proved that the lesion was a cavernous hemangioma. Epistaxis completely stopped and nasal obstruction improved. There was no recurrence of the lesion throughout the 12-month follow-up.
| Discussion|| |
Cavernous hemangioma is usually composed of large endothelium-lined vascular spaces with unclear pathogenesis and without degenerative potential. When hemangiomas arise in the nasal cavity, they are predominantly of the capillary type and arise from the anterior part of the nasal septum in about 80% of the cases, namely at the Little’s area or Kiesselbach’s triangle 
In the current case report, we described the first nasopharyngeal hemangioma with attachment to the posterior end of the nasal septum. Only two nasopharyngeal hemangiomas have been previously reported , and both originated from the left nasopharyngeal wall ([Table 1]).
The current case presented with left recurrent severe epistaxis and bilateral nasal obstruction, while the two previously nasopharyngeal heamangiomas complained of left nasal obstruction with severe left epistaxis. So cavernous hemangiomas should be suspected in the differential diagnosis of severe epistaxis and that of the nasopharyngeal mass.
The radiological features, however, do not always give the differential diagnosis with the most common epithelial tumors . Thrombi within the vascular spaces may occasionally calcify and are identified at CT as phleboliths . Evidence of phleboliths and calcifications may suggest the presence of a cavernous hemangioma. However, it is not always present, so the definitive diagnosis is histological. In our patient, calcifications were seen in her CT, together with the severe bleeding suggested the lesion to be a hemangioma and no biopsy was taken before the definitive surgery similar to the case reported by Testa et al. .
Punch biopsy was not done because the mass was covered by mucosa and was highly vascular and bleed severely on touch. This is in agreement with the previously reported nasopharyngeal cavernous hemangiomas , ([Table 1]).
Management of nasal hemangioma involves complete resection of the tumor with a part of the underlying mucosa and perichondrium and ligation or cautery to the feeding vessels . This was applied in the current case.
An alternative form of management of these tumors, providing there is favorable anatomy, is embolization of the haemangiomas, which is, however, only possible if appropriate angiographic facilities are available. Angiography needs to detect the precise arterial supply of the lesion and there is always a possibility of complication such as visual affection. Radiation therapy is reserved for arresting the progression of unresectable or inaccessible lesions 
In the absence of risk of malignant transformation, the transnasal endoscopic approach [functional endoscopic sinus surgery (FESS)] has been proposed as the technique of choice for the complete removal of the tumor in cases of haemangiomas confined to the nasal cavity and extended into the ethmoid to the sphenoid sinus . So endoscopic excision was the chosen treatment in current cases and previously reported nasopharyngeal carcinomas ,.
Follow-up is necessary in order to identify recurrences, which may occur late.
The unusual site of origin and unspecific clinical appearance can make the diagnosis and treatment of a cavernous hemangioma of the nasopharynx difficult, but it should be considered in such cases particularly those complained of epistaxis.
In the present case, the minimally invasive transnasal endoscopic technique has proven to be reliable in terms of adequate exposure and visualization of the lesion, control of bleeding, and complete removal of the tumor. A similar approach was used effectively by Testa et al.  and Khil et al. .
Although some authors used preoperative embolization , embolization was not done in the current case. However, control of bleeding and complete removal of the mass was achieved during the surgery. This was helped by sphenopalatine artery ligation and submucosal dissection of the posterior septum till the origin of the lesion was reached, cauterized, and separated.
| Conclusion|| |
To the best of our knowledge, this is the first description of nasopharyngeal cavernous hemangioma originating from the posterior end of the nasal septum. Tnsanasal endoscopic technique was a reliable safe and effective approach for complete hemangioma removal with control of bleeding.
Bullet point summary
- A female case is presented of repeated severe epistaxis and nasal obstruction was reported to have nasopharyngeal cavernous heamangioma originating from the posterior end of the nasal septum.
- Transnasal endoscopic approach permits adequate exposure and complete excision of the hemangioma.
- Cavernous hemangioma should be considered in the differential diagnosis of the nasopharyngeal mass and in cases with repeated epistaxis.
