Capillary hemangioma in a rib presenting as large pleural effusion

Rib Hemangiomas: Intriguing Findings from a Systematic Review of Rare Thoracic Tumors

Background: Bone hemangiomas are rare benign vascular tumors, comprising less than 1% of all bone tumors. They are predominantly found in the vertebral body or skull; rib hemangiomas are particularly rare and are often misdiagnosed as malignant tumors. Given the high malignancy rate of primary rib tumors, understanding rib hemangiomas is crucial to avoid misdiagnosis. Methods: A systematic review was conducted according to PRISMA standards. A comprehensive literature search was performed in PubMed, EMBASE, Web of Science, and Scopus. Data on patient demographics, tumor characteristics, and clinical presentation were analyzed using STATA/SE 17. Results: From 306 articles, 40 studies including 43 patients met the inclusion criteria. Rib hemangiomas showed a bimodal age distribution, with peaks in patients younger than 30 years (mean age 21.43 ± 5.60 years) and ≥30 years (mean age 59.96 ± 9.70 years). Females were more affected (62.79%) than males (37.21%), with a ratio of 1.69:1. The tumors were most frequently located in mid-thoracic ribs (4-8) and predominantly on the left side of the thorax. The mean tumor size was 7.27 cm, with 76.19% exhibiting osteolytic changes. Clinically, 63.41% of cases were asymptomatic, while symptomatic cases mainly presented with pain. Conclusions: Rib hemangiomas, though rare, should be considered in the differential diagnosis of thoracic tumors. They present as well-demarcated lytic lesions with distinct imaging features, and they typically require complete surgical excision, which may be aided with preoperative embolization. Their accurate diagnosis involves a combination of radiologic and clinical evaluation. Further studies are needed to understand the disease's pathophysiology and to refine diagnostic and treatment protocols.

Treatment of left tenth rib haemangioma vascularised by a costal artery giving the artery of Adamkiewicz

Haemangioma of the ribs is considered an extremely rare benign tumour. Here, we present a case of a young male with left tenth rib haemangioma vascularised by a costal artery giving the artery of Adamkiewicz presented as chronic cough. This was successfully treated through preoperative embolisation and surgical resection. A preoperative angiogram was performed to identify the origin of the artery of Adamkiewicz. The final diagnosis was confirmed histopathologically. There were no complications in the postoperative course and no recurrence during 12 months of follow-up.

Multifocal pleural capillary hemangioma: a rare cause of hemorrhagic pleural effusion-case report

Background

Capillary hemangioma can be found in many organs, but rarely in pleura. Previously, only localized pleural capillary hemangioma cases have been reported. Corticosteroids are the most commonly recommended drugs in capillary hemangioma.

Case presentation

Here, we present a case of a young woman with recurrent hemorrhagic pleural effusion. Despite repeatedly thoracentesis, the routine examinations, including chest computed tomography (CT) scan, pleural effusion biochemical test, and cytology all failed to make a definite diagnosis. Thus, single port video-assisted thoracoscopy (VATS) was then performed. Numerous nodules arising from the parietal pleura were found, and biopsies showed multifocal pleural capillary. However, recurrent pleural effusion was successfully managed by oral azathioprine, after failure of dexamethasone treatment.

Conclusions

To our knowledge, this is the first case of a patient with recurrent hemorrhagic pleural effusion masquerading as malignant pleurisy, but in fact caused by multifocal pleural capillary hemangioma.

Incidentally found rib hemangioma: case report and discussion of management

Rib hemangioma is a rare chest wall tumor for which few reports in the literature exist to help guide treatment. The clinical presentation, radiographic findings, and treatment strategies vary in the literature, with the majority of patients undergoing surgical resection to definitively rule out malignancy. Here, we report a 23-year-old woman with an incidentally discovered rib hemangioma, who had a history of migraines, during the workup of a severe headache refractory to medical treatment. Imaging revealed a solitary, expansile tumor arising from the posterior left third rib. Spinal magnetic resonance imaging (MRI) showed a fat-containing lesion with multiple vascular flow voids, non-enhancement, and high signal intensity on the T2-weighted series. It appeared to have a honeycomb core on chest computed tomography (CT). Imaging characteristics of the lesion were consistent with an intraosseous hemangioma. The tumor was managed with upfront surgical resection without a preoperative biopsy. The case was uneventful and no complications were encountered. The patient recovered well, denied any symptoms four weeks after surgery, and a follow-up chest X-ray was unremarkable. Following resection, the pathological diagnosis was concordant with the radiographic diagnosis of a rib hemangioma. Here, we review existing literature on the rare case of a rib hemangioma with a focus on the radiographic characteristics and management. Given that radiographic features of this lesion were consistent with prior reports and surgery did not change the diagnosis, we suggest that non-operative management be considered for similar lesions, as surgical resection does not appear to reveal occult malignancy in the majority of cases.

Hemangioma of the rib showing a relatively high 18F-FDG uptake: a case report with a literature review

Hemangioma of the rib is a rare benign tumor that is often difficult to distinguish from malignant bone tumors. Rib hemangioma often shows bony disruption with a slight cortical disruption, extraosseous lesion, and expanded bone on computed tomography (CT). We report the case of a 68-year-old man with atypical rib hemangioma with a slight cortical disruption and no expanded bone. The tumor showed relatively high 18FDG-uptake on positron emission tomography (PET)/CT. Rib hemangioma often shows higher 18FDG-uptake. PET/CT may not provide useful information for distinguishing rib hemangioma from a malignant tumor. Close observation without surgical resection may be feasible if the tumor is diagnosed as a rib hemangioma by biopsy.

Hemangioma of the Rib: A Rare Case Report and Literature Review

Hemangiomas of the rib are extremely rare benign neoplasm. Here we present a case in a 47-year-old female, detected by chest X-ray and underwent a surgical resection. Histologically, the tumor was composed of a homogeneous conglomerate, irregular, thin walled and dilated blood vessels containing red blood cells, supported by fibrous stroma and intermingled to regular bone trabeculae. The postoperative courses were uneventful, and there was no recurrence during 64 months follow-up.

Chest wall resection for multifocal osseous haemangioma

Intraosseous haemangioma is a rare and benign primary tumour of the bone. We report the case of a 76-year old woman who presented the exceptional condition of multifocal cavernous haemangiomas involving the spine and the ribs, requiring spinal and chest wall resections to confirm the diagnosis and treat the symptoms.

A rare case report of rib hemangioma mimicking a malignant bone tumor or metastatic tumor

•

Hemangioma of the rib is a rare benign vascular tumor.

•

The chest computed tomography or magnetic resonance imaging of this disease often reveals malignant findings.

•

Hemangioma of the rib should be considered in the differential diagnosis of malignant bone tumor.

Hemangioma of the rib is a rare benign vascular tumor. This benign disease induces osteolytic changes, and must be distinguished from a malignant bone tumor or metastatic tumor. Definitive diagnosis is achieved by excision biopsy or histological examination after surgical resection in many cases. We here in present a rare case of hemangioma of the rib.
