Unusual cause of 55 years of rectal bleeding: hemolymphangioma (a case report)

Focal hemolymphangioma of the rectum: A case report and literature review

RATIONALE

Gastrointestinal hemolymphangiomas are very rare, especially in the rectum. Only 3 cases of rectal hemolymphangioma, all of which are diffuse lesions, have been reported in the English literature on PubMed. Our case is the first focal lesion of the rectum. It is important for radiologists to correctly identify the imaging features of rectal hemolymphangiomas.

PATIENT CONCERNS

A 51-year-old woman visited our hospital because of intermittent constipation for 3 years.

DIAGNOSES

Colonoscopy revealed a prominent lesion on the left anterior wall of the lower rectum. Transvaginal color Doppler ultrasonography showed that the posterior vaginal wall area had a mixed-echo mass, and blood flow signals of the dots and stripes could be seen. Pelvic magnetic resonance imaging showed that the cystic space-occupying lesion in the region between the left anterior wall of the lower rectum and the posterior wall of the middle and lower vagina had a clear boundary.

INTERVENTIONS

The patient underwent surgery to remove the rectal lesions. The surgical specimen was finally diagnosed as local hemolymphangioma by pathological analysis.

LESSONS

Localized hemolymphangioma of the rectum is very rare, and imaging examination is essential for the diagnosis and evaluation of the extent of lesion invasion.

Cystic Lymphangioma of Rectum-A Case Report and Review of Literature

Colorectal cystic lymphangiomas are rare benign lesions. They are characterized by the presence of either single or multi-cystic spaces lined by endothelium. Though there are multiple case reports of right and transverse colonic lymphangioma; only around 10 cases of lymphangioma of the rectum have been reported. We present a case report of rectal lymphangioma with the relevant literature review.

Hemolymphangioma involving bones and bladder detected on 68Ga-NEB PET/CT: A rare case report

RATIONALE

Hemolymphangioma is a rare developmental defect of combined vasal and lymphatic vasculature. It is very rare that hemolymphangioma affects the bones and bladder simultaneously, and this condition has never been reported in PubMed.

PATIENT CONCERNS

A 12-year-old male has a history of hospitalization for recurrent episodes of chyluria of 8 years duration and progressively worsening gross hematuria with right hip pain for 6 months.

DIAGNOSIS

Chylous test of urine fluid was positive. There was no organic disease in the kidneys. Ga-NOTA-Evans Blue (NEB) positron emission tomography/computed tomography (PET/CT) images demonstrated clearly several round and strip-shaped low-density shadows with mildly increased radioactive uptake in both bladder wall and pelvis, including sacral, pubic, and ischial bones. Histopathological analysis of biopsy on pubic and ischial bones confirmed the diagnosis of hemolymphangioma.

INTERVENTIONS

The patient received treatment with traditional Chinese medicine.

OUTCOMES

At the 6-month follow-up visit, the patient's symptoms of chyluria, hematuria, and pain were all mitigated.

LESSONS

Hemolymphangioma is a rare benign disease. Ga-NEB PET/CT is a specific method for the lymphatic system, and it might provide more accurate and comprehensive information about the disorder of the lymphatic system compared with CT and magnetic resonance imaging. When patients suffer from suspected lesions of the lymphatic system, Ga-NEB PET/CT might be recommended.

Occipitocervical Hemolymphangioma in an Adult with Neck Pain and Stiffness: Case Report and Literature Review

Introduction

Hemolymphangioma is an extremely rare malformation of the lymphatic and blood vessels. A limited number of hemolymphangioma cases occurring in the pancreas, extremities, spleen, and other organs have been reported until September 2017. To the best of our knowledge, no cases of hemolymphangioma in the occipitocervical region have been reported in the literature.

Case Presentation

We reported the case of a 23-year-old male patient with an occipitocervical lesion presenting atypically as neck pain and stiffness over a period of five months. Although hemolymphangioma has historically demonstrated a female predilection (2.25 : 1 female to male) and presentation in the third to fourth decades of life, this case is an atypical manifestation occurring in a young male patient. The clinical characteristics and management choices of this uncommon case of hemolymphangioma in the occipitocervical region are discussed, and a review based on the available literature is also presented.

Conclusion

Hemolymphangioma of the occipitocervical region is an uncommon presentation of a rare lesion. Although rare, hemolymphangioma should be considered a differential diagnosis for masses occurring in the occipitocervical region. Complete surgical resection is the treatment of choice and affords a good prognosis.

Radiographic findings of hemolymphangioma in four patients: A case report

Due to the rarity of hemolymphangioma, a limited number of cases of the disease have been reported in the literature thus far. The present case report describes the cases of 4 patients with hemolymphangioma that were diagnosed and treated at the Second Affiliated Hospital of Xi'an Jiaotong University (Xi'an, China). All patients were female, with a mean age of 44.7 years and a mean duration of symptoms prior to diagnosis of 2.7 years. The diagnosis of hemolymphangioma was determined by postoperative histopathology in all patients. A total of 2 patients were diagnosed with tumors that exhibited cystic characteristics (one in the mediastinum and the other in the neck), which was determined by computed tomography and magnetic resonance imaging. Another of the patients' tumors was located in the left forearm, and 1 patient had multifocal hemolymphangioma in the mediastinum and spleen. All patients underwent surgery and were asymptomatic during the follow-up periods (range, 8–15 months). In the present case report, the radiographic findings of the 4 cases are presented, including the unusual imaging characteristics that were observed, and relevant reports in the literature are discussed.
