Adrenal cavernous hemangioma: a case report

Retroperitoneal cavernous hemangioma misdiagnosed as lymphatic cyst: A case report and review of the literature

BACKGROUND

Primary abdominal and retroperitoneal cavernous hemangioma is a vascular tumor and rarely seen in the clinic. Due to the lack of specific imaging features, retroperitoneal cavernous hemangioma cannot be diagnosed accurately. Some symptoms may develop with the enlargement of lesion volume or the occurrence of complications such as rupture or oppression. We report here a special case who was admitted with chronic abdominal pain. Admission examination suggested a retroperitoneal lymphatic duct cyst. Laparoscopic resection of the retroperitoneal mass was performed, and histological examination confirmed retroperitoneal cavernous hemangioma.

CASE SUMMARY

The patient was a 43-year-old Tibetan woman with intermittent left lower abdominal pain and discomfort 3 years ago. Ultrasonography revealed a cystic mass in the retroperitoneum with clear boundaries, internal septa, and no blood flow signal. Computed tomography (CT) and magnetic resonance imaging (MRI) showed an irregular space-occupying mass in the retroperitoneum, and retroperitoneal lymphatic cyst was considered. Plain CT scanning showed multiple cyst-like hypo-intense shadows in the retroperitoneum, partially fused into a mass, and no obvious enhancement was found on enhanced scanning. MRI showed multiple irregular clump-like long T1 and long T2 signal shadows above the pancreas, within which linear short T2 signal shadows were seen. Diffusion-weighted imaging sequence showed hypo-signal shadows, without obvious enhancement on enhanced scanning. Ultrasound, CT, and MRI all suggested the possibility of retroperitoneal lymphatic cyst. However, the patient was finally diagnosed with retroperitoneal cavernous hemangioma by pathological examination.

CONCLUSION

Retroperitoneal cavernous hemangioma is a benign lesion, and it is difficult to make a diagnosis preoperatively. Surgical resection may be the only treatment, which not only allows histopathological confirmation as a diagnostic purpose and excludes any risk of malignancy, but also avoids invasion of adjacent tissues, oppression, and other complications as a therapeutic goal.

Incidental adrenal hemangioma clinically suspicious for malignancy: diagnostic considerations and review of the literature

Adrenal hemangiomas are rare lesions often found incidentally during unrelated diagnostic work-up. We report a case of a 67-year-old man with history of hypertension, hyperlipidemia, anemia, arthralgia, joint swelling and unexplained weight loss, which prompted imaging studies. Computed tomography scan revealed a 5.4 cm adrenal mass. The patient had no clinical manifestations of adrenal medullary or cortical hyperfunction. Urine and plasma metanephrines and aldosterone/renin ratio were within normal range. The patient was taking prednisone for hand and ankle swelling, precluding assessment for Cushing syndrome. Given the size of the lesion, the possibility of malignancy was considered, and the patient elected for surgical management. The left adrenalectomy specimen weighed 54 g and revealed a 4.9 cm tan-brown mass with congested cut surface and a thin rim of residual adrenal gland parenchyma. Histologic examination showed thick and thin-walled vessels intermingled with adrenocortical elements at the periphery characteristic of a hemangioma. Surgical resection is the mainstay treatment for large, isolated adrenal masses to exclude malignancy and prevent retroperitoneal hemorrhage. Herein, we report a case of adrenal hemangioma, review a variety of other diagnostic considerations occurring in the adrenal gland, and highlight useful distinguishing features to assist in accurate diagnosis.

A case of retroperitoneal venous malformation resected by laparoscopic surgery

Introduction

Among vascular malformations, venous malformations are the most common type. Among these, retroperitoneal venous malformations are extremely rare.

Case presentation

A 60‐year‐old woman was diagnosed with a retroperitoneal tumor 4.5 cm in diameter by abdominal computed tomographic scan. We had difficulty judging whether the tumor was benign or malignant. We performed laparoscopic surgery in order to remove the tumor and make a precise diagnosis. The pathological diagnosis was a venous malformation.

Conclusion

Venous malformation located in the retroperitoneum is very rare, and there were few cases that could be removed by laparoscopic surgery. Laparoscopic surgery may be beneficial both for treatment and diagnosis of patients with a small retroperitoneal venous malformation.

Bloom where you are planted: Hemangioma or malignancy?

Vascular anomalies comprise a spectrum of disorders characterized by the abnormal development or growth of blood and lymphatic vessels. These growths have unique features and diverse behaviors, mandating a multidisciplinary approach in their evaluation, diagnosis, and management. Here we describe the case of a male toddler presenting with an abdominal mass, originally treated as a metastatic retroperitoneal tumor, but subsequently felt to represent a vascular anomaly.

Imaging findings and 4 years follow-up of adrenal cavernous hemangioma: a case report

Background

Adrenal hemangioma is a rare and non-functional benign tumor. Since the first case in 1955, approximately 90 cases have been reported in literature frequently presenting as a large and incidentally discovered retroperitoneal mass or as a result of hemorrhage caused by spontaneous rupture.

Case presentation

A 69-year-old man was admitted to our hospital for right hypocondrium pain and anemia. A computed tomography (CT) scan was performed and a large right adrenal mass measured 18 cm was found.

The patient underwent laparoscopic right adrenalectomy. Histopathological diagnosis revealed a cavernous adrenal hemangioma.

Conclusion

Cavernous hemangiomas are uncommon tumors. We reported a case of adrenal cavernous hemangioma incidentally discovered by ultrasound and CT. In the case of finding adrenal masses, cavernous hemangiomas, although rare, should be considered a possible diagnosis.

The appropriate treatment is surgical resection to rule out any potential for malignancy, to relieve symptoms secondary to the mass effect, and to prevent complications such as retroperitoneal bleeding.

[Adrenal cavernous hemangioma: A case report and literature review]

A 57-year-old male patient was referred to our department with complaints of his right adrenal gland occupancy and hypertension about 6 months. When admitted to the hospital, the blood pressure was about 160/100 mmHg, and the heart rate was 110 beats/min. He was no obvious obesity, acne, abnormal mood, without weakness of limbs, acral numbness, palpitation and headache. He presented with type 2 diabetes for more than 3 years, with oral administration of metformin enteric coated tablets and subcutaneous injection of insulin glargine to control blood glucose, and satisfied with blood glucose control. Enhanced CT showed that: the right adrenal gland showed a kind of oval isodense, slightly hypodense shadow, the edge was clear, lobular change, the size was about 5.8 cm×5.4 cm, uneven density, there were nodular and strip calcification, round lipid containing area and strip low density area, and the CT value of solid part was about 34 HU. Enhanced scan showed heterogeneous nodular enhancement in the solid part of the right adrenal gland, nodular enhancement could be seen inside. The CT values of solid part in arterial phase, venous phase and delayed phase were 45 HU, 50 HU and 81 HU, respectively. Considering from the right adrenal gland, cortical cancer was more likely. No obvious abnormality was found in his endocrine examination. After adequate preoperative preparation, retroperitoneal laparoscopic adrenalectomy was performed under general anesthesia. During the operation, the 6 cm adrenal tumor was closely related to the inferior vena cava and liver, and after careful separation, the tumor was completely removed and normal adrenal tissue was preserved. The operation lasted 180 min and the blood loss was 100 mL, and the blood pressure was stable during and after the operation. There was no obvious complication. The results of pathological examinations were as follows: the size of the tumor was 7.5 cm×6.0 cm×3.5 cm, soft, with intact capsule and grayish-red cystic in section. Pathological diagnosis: (right adrenal gland) cavernous hemangioma, secondary intravascular thrombosis, old hemorrhagic infarction with calcification and ossification. After 6 months of observation, no obvious complications and tumor recurrence were found. In summary, cavernous hemangioma of adrenal gland is a rare histopathological change. Its essence is a malformed vascular mass. Blood retention is the cause of thrombosis and calcification in malformed vessels. The imaging findings were inhomogeneous enhancement of soft tissue masses, and the adrenal function examination showed no obvious abnormalities. Retroperitoneal laparoscopic surgery is feasible after adequate preoperative preparation. It is difficult to diagnose the disease preoperatively and needs to be confirmed by postoperative pathology.

A Rare Presentation of Lisegang Rings in Adrenal Cavernous Hemangioma : Case Report and Literature Review

BACKGROUND

Adrenal cavernous hemangiomas (AH) are benign nonfunctional vascular tumors rarely discovered as incidental findings on imaging studies or autopsies. This study presents a single case report of AH with another rare finding of the Liesegang ring. Also, we reviewed 73 case reports of cavernous adrenal hemangioma to provide an overview of AH's clinical characteristics. Case Report. A nonfunctional AH was incidentally discovered in a 59-year-old morbidly obese female patient with a 10-year history of hypertension and thyroidectomy. An abdominal computed tomography (CT) scan showed a left suprarenal mass of ∼16 cm in diameter. While the patient had no clinical manifestations from the hemangioma, all laboratory tests were within the normal values with no indication of a functional adrenal tumor. The mass was removed by open left adrenalectomy. The microscopic histological examination revealed a laminated structure with wide blood-filled spaces with a central core of necrotic and hemorrhagic changes, characteristic of a cavernous AH with the presence of a rare Liesegang ring.

CONCLUSION

Although rare, AH should be considered as a differential diagnosis for adrenal masses. This is the first reported case of a cavernous AH with rare microscopic findings of the Liesegang ring.

Adrenal Hemangioma: A Common Tumor at Uncommon Site

Adrenal hemangiomas are rare vascular tumors. These are benign, mostly nonfunctioning and asymptomatic. Cavernous adrenal hemangiomas are more common in the elderly, with female preponderance. A computed tomography (CT) scan can diagnose their benign nature. Most cases are managed surgically, and laparoscopy is the most common approach followed nowadays.

A young female presented with nausea, pain, and a vague mass palpable in the right abdomen. With CT findings favoring benign lesion or nonfunctioning adenoma but symptomatic, the patient had to undergo diagnostic laparoscopy and adrenalectomy. Adrenal hemangiomas are rare lesions. Moreover, involving a young female further makes their diagnosis difficult. Hence, they must be kept as one of the differential diagnosis in evaluation of adrenal mass in young females.

Adrenal hemangioma: A rare presentation of bleeding incidentaloma: Case report

•

Adrenal incidentalomas are tumors found accidentally by imaging.

•

Hemangiomas are quite rare and in certain cases their surgical intervention should never be overlooked.

•

Embolization is primarily implied but one should never neglect the failure rate and the need for surgical intervention.

•

There are 4 types of AH: cavernous hemangioma, venous hemangioma, capillary type hemangioma, and mixed hemangioma.

•

To our knowledge, our case has the largest size of an AH being reported in the literature with a 17 cm.

Introduction

Adrenal incidentalomas are tumors found accidentally by imaging. Among the incidentalomas, hemangiomas are quite rare and in certain cases their surgical intervention should never be overlooked.

Presentation of case

We present a case of 70 years old Lebanese female with an adrenal tumor presented as syncope found to have anemia on presentation and a bleeding 17 cm adrenal tumor on imaging. Patient had workup to rule out functioning adrenal tumors and decision to excise the tumor was taken after failure of embolization. Pathology report denied malignancy despite of the huge size and was in favor of hemangioma.

Conclusion

Adrenal hemangiomas are rare and they rarely present as syncope. Attention to such a life-threatening condition should be sustained. Embolization is primarily implied but one should never neglect the failure rate and the need for surgical intervention.

DaVinci robotic-assisted laparoscopic resection of parapelvic cavernous hemangioma: a case report

Background

Cavernous hemangioma, as a rare tumor, is difficult to differentiate from retroperitoneal lymphoma and paraganglioma. They are more difficult to excise completely through open surgery and traditional laparoscopic surgery. The study aimed to evaluate the role of DaVinci surgical system in laparoscopic resection of parapelvic cavernous hemangioma.

Case presentation

A 46-year-old female, who diagnosed as parapelvic cavernous hemangioma accompanying with thrombosis and calcification, was performed laparoscopic resection using DaVinci surgical system under general anesthesia. The patient well recovered without recurrence or spread of the lesion after operation for 3 months as well as hydronephrosis was significantly relieved.

Conclusion

Laparoscopic resection of parapelvic cavernous hemangioma under the help of DaVinci surgical system was feasible and safe.

Adrenal cortical carcinoma: pathology, genomics, prognosis, imaging features, and mimics with impact on management

Adrenocortical carcinoma (ACC) is a rare tumor with a poor prognosis. Most tumors are either metastatic or locally invasive at the time of diagnosis. Differentiation between ACC and other adrenal masses depends on clinical, biochemical, and imaging factors. This review will discuss the genetics, pathological, and imaging feature of ACC.

Adrenal Cavernous Hemangioma: A Rarely Perceived Pathology-Case Illustration and Review of Literature

Cavernous hemangiomas are endothelial tumors that rarely affect the adrenal glands. Most of these tumors remain silent and are incidentally found on abdominal imaging. Hardly ever, these tumors are endocrinologically functional. They may present as vague abdominal pain. Surgical resection remains the mainstay for large masses. In this paper, we are presenting a case of adrenal cavernous hemangioma in a 83-year-old male patient who initially presented for workup of vague abdominal and bilateral flank pain. A computed tomography scan of the abdomen showed an 8 cm right adrenal adenoma which was metabolically nonfunctional. The mass was completely resected through an open subcostal incision, with no encountered postoperative complications. A highlight of all published cases of adrenal hemangiomas since 1955 is also presented and reviewed.
