Lymphangioma: Imaging diagnosis

Recurrent Neck Lymphangioma in a Young Adult: Twenty-Three Years After Successful Treatment

Lymphangiomas are rare benign malformations of the lymphatic system, commonly present in children, over the head and neck area. Occasionally, they can grow significantly in size and especially those located over the cervical region can cause airway obstruction and become life-threatening. Recurrent lymphangiomas usually occur during the early postsurgical period and 80% of them within the first 3 to 5 years. However, in a new onset of clinical manifestations affecting the head and neck, even many years after the successful surgical treatment, a recurrent lymphangioma should be considered in the differential diagnosis. We present herein the second reported case, to our knowledge, of a recurrent left-sided neck lymphangioma in a young man, 23 years after a successful surgical treatment that initially took place 6 weeks after his birth.

A case of mesenteric cystic lymphangioma in an adult which caused duodenal stenosis after resection

INTRODUCTION

We present a rare case of mesenteric lymphangioma in a middle-aged female.

PRESENTATION OF CASE

A 56-year-old female was admitted to the hospital with upper abdominal pain. Abdominal computed tomography revealed a multicystic mass surrounding the mesentery. We made the decision to resect the mass, suspecting that was a mesenteric lymphangioma based on additional imaging studies. The tumor adhered strongly to parts of the duodenum and the upper jejunum. In order to preserve the jejunum, we dissected its serosa away from the tumor. Approximately 1 week after surgery the patient experienced a constriction of the third portion of the duodenum. Her symptoms were improved with conservative therapy, and she was discharged from the hospital 62 days after surgery.

DISCUSSION

Lymphangioma originating from the mesentery may have cause adhesions due to exfoliated tumor cells; it is necessary to be concerned about postoperative obstruction.

CONCLUSION

The preoperative diagnosis of lymphangioma is based on various imaging modalities.

Pulmonary lymphangioma in a 14-month-old

Intrapulmonary lymphangiomas are very rare. We report a case of a 14-month-old child found to have a pulmonary lymphangioma on routine chest radiograph in the emergency department and discuss the possible implications and appropriate management of this condition by the emergency physician.

Sclerotherapy for cervical cystic lymphatic malformations in children. Our experience with computed tomography-guided 98% sterile ethanol insertion and a review of the literature

PURPOSE

The treatment of cystic lymphatic malformations of the neck and mediastinum is controversial. Surgical management may be limited by the invasiveness of the procedure, the complex anatomy of this region, and the high recurrence rate. An alternative therapeutic method is sclerotherapy. We report our experience in the treatment of cystic lymphatic malformations of the neck by computed tomography (CT)-guided instillation of 98% sterile ethanol in children.

METHODS

Eight children with clinical suspicion of cervical cystic lymphatic malformation were assessed by ultrasonography (US) and magnetic resonance imaging (MRI) to define the location, size, and number of cystic cavities. The CT-guided instillation of 98% sterile ethanol was performed. Cystic fluid was analyzed by fine-needle aspiration cytology. Clinical and US or MRI follow-up was performed after 1 and 3 months and at 1 and 2 years.

RESULTS

The results were excellent with complete disappearance of the lesion in 7 (87.5%) of 8 patients. One patient (12.5%) with satisfactory results required a second alcohol injection with an excellent outcome. No allergic reactions or complications were observed.

CONCLUSIONS

The CT-guided 98% sterile ethanol sclerotherapy is a good alternative to surgical therapy. This procedure seems accurate, minimally invasive, safe, low cost, and reliable without untoward complications. Moreover, it does not exclude later surgical treatment.

[A gigant cystic lymphangioma of the neck]

The cystic lymphangiomas are congenital pathology of lymphatic system which concern 90% of children population, adults suffer very seldom. The authors present the case of giant cystic lymphangioma of the neck in the 37-year-old man with symptoms of tumor of the neck. The USG, CT and MRI confirm the presence of polycystic tumour with feature of bleeding into one of the cavities. Surgical treatment was performed. The patient is controlled without any relaps. The authors remind this rare pathology that should be considered in case of neck tumours.

A case of mesenteric cystic lymphangioma: fat saturation and chemical shift MR imaging

Mesenteric cystic lymphangioma is an uncommon lesion that may be difficult to diagnose radiologically. In our case, a septate cystic mass showed fluid attenuation on a computed tomography scan. We were able to define the fat content within the cystic tumor by magnetic resonance (MR) imaging. The presence of fat within an intra-abdominal cystic mass is suggestive of a dermoid cyst, cystic lymphangioma, or lymphocele. The pathologic diagnosis revealed a cystic lymphangioma, which originated from the mesentery. Although the MR imaging features of dermoid cysts and lymphangiomas are well known, the demonstration of fat content by chemical shift and fat saturation MRI has not yet been reported for a cystic lymphangioma.

Cystic hygroma in the quadriceps muscle: a sanguine diagnosis for knee pain

Reported here is a 28-year-old female who presented with severe right knee pain and swelling nearby the joint. Ultrasonography, magnetic resonance imaging and eventually surgery were performed. She was diagnosed to have a cystic hygroma in the vastus lateralis muscle. This is the first patient of a cystic hygroma in the quadriceps muscle.

Cystic lymphangioma confined to mediastinum in an adult

Mediastinal lymphangiomas are very rare tumors among the slow-growing mediastinal masses in the literature. We present the successful resection of a 52-year-old woman who was referred to our hospital. Past medical history consisted of surgical treatment for cervical mass and pathological diagnosis of lymphoma nine years earlier. She underwent postoperative radiotherapy. Preoperative chest roentgenogram and computed tomogram of the chest showed a cystic mass in the anterior mediastinum. The tumor was completely resected. The preoperative diagnosis was never questioned until the histopathological examination confirmed that the lesion was a cystic lymphangioma. Cystic lymphangiomas are benign tumors with the evidence of progression in tumor size and invasion into the vital structures. As our case shows, the tumor involvement with the vital structures causes difficulty in removal.

Lymphangioma of the kidney

Lymphangiomas are rare benign tumors that are congenital malformations of the lymphatic system. Most cases present in children as a soft, cystic mass in the neck and the axilla. Primary renal lymphangioma is exceedingly rare, with only 35 cases reported so far. We report a case of primary lymphangioma arising from the kidney. A 59-year-old man was referred for evaluation of a right renal mass found in an abdominal ultrasonography during a health checkup. Abdominal ultrasonography and computed tomography (CT) revealed a 3.2 x 2.9 cm multiloculated cystic mass in the upper pole of the right kidney. We could not deny malignant disease such as cystic renal cell carcinoma with any diagnostic modalities. The patient was brought to surgery. During the surgical procedure, the tumor was suspected to be lymphangioma of the kidney as a result of a frozen- section histopathological evaluation. Therefore enucleation of the tumor was performed. Pathological evaluation of the specimen revealed lymphangioma arising from the kidney. The patient is free of disease after a 3-month follow-up period.

Prenatal ultrasound findings of fetal neoplasms

A variety of neoplasms can develop in each fetal organ. Most fetal neoplasms can be detected by careful prenatal ultrasonographic examination. Some neoplasms show specific ultrasonographic findings suggesting the differential diagnosis, but others do not. Knowledge of the presence of a neoplasm in the fetus may alter the prenatal management of a pregnancy and the mode of delivery, and facilitates immediate postnatal treatment. During the last five years, we experienced 32 cases of fetal neoplasms in a variety of organs. We describe their typical ultrasonographic findings with correlating postnatal CT, MRI, and pathologic findings.

Cystic hygroma: Presentation of two casfes with a review of the literature

Two interesting cases of cystic hygroma are being reported. One presented with dyspneoa and the other one with macroglosia and mediastinal cystic hygroma. The foetal chromosomal anomalies associated with cystic hygroma, intrauterine diagnosis and treatment of cystic hygroma as well as pathogenesis, classification, surgical and non-surgical management of cystic hygroma has been discussed in detail in the review of the literature.

25 years' experience with lymphangiomas in children

BACKGROUND/PURPOSE

The management of lymphangioma in children is challenging because complete resection is difficult to achieve in some cases, and recurrences are common. The authors reviewed their experience to assess the risk factors for recurrence and the role of nonoperative treatment.

METHODS

A retrospective study over a period of 25 years was carried out. One hundred eighty-six patients with 191 lesions (five patients with de novo lesions in different sites) were treated. There were 98 boys and 88 girls. The average age at diagnosis was 3.3 years (range, fetal life to 17 years) and the average size 8 cm in diameter. Histocytological confirmation was obtained in all patients. The involved sites were head and neck, 89 patients (48%); trunk and extremities, 78 patients (42%); internal or visceral locations (eg, abdominal and thorax), 19 patients (10%). The treatment consisted of macroscopically complete excision in 145 patients (150 lesions, of which five were recurrences in different sites), partial excision in 10 patients, aspiration in five patients, laser excision in 10 patients, biopsy only in four patients, drainage and biopsy in two patients, and injection of sclerosing agents in 10 patients.

RESULTS

There were 54 recurrences; 44 underwent excision (five of them more than once), and five regressed spontaneously on follow-up. Five other recurrences were stable and not progressing. Recurrences, (defined as clinically obvious disease), were found to be 100% after aspiration, 100% after injection, 40% after incomplete excision, 40% after laser excision, and 17% after macroscopically complete excision. The recurrence rate in the last group was the highest in the head (33%), the least in the internal locations (0%), and intermediate for the cervical location (13%). There were no significant differences, in terms of outcome, between those who had their surgery immediately at the time of diagnosis (n = 101) and those who had delayed surgery (n = 85).

CONCLUSIONS

There were fewer recurrences after macroscopically complete excision. Aspiration and injection had the highest recurrence rate. Risk factors for recurrence included location, size, and complexity of lesions. A period of observation may be useful for infants to facilitate complete excision. In the present series, spontaneous regression was infrequent and was seen more often with recurrent lesions.
