technetium-tc-99m-medronate and Hemangioma

Hemangiolymphangioma is a very rare, congenital malformation of both lymphatic and blood vessels. In the present study, we report a case of vertebral hemangiolymphangioma that was misdiagnosed as bone metastasis on 99mTc-MDP SPECT/CT.

A 31-year-old woman visited an out-patient clinic, because of low-grade fever and general fatigue. She was referred to our hospital and admitted for examination of an abnormal shadow which had been found on the chest radiograph. She had experienced faint right lateral chest pain several times on the deep inspirations. Chest radiography showed a mass shadow with calcification in the right lower lung field on the mediastinal side. Chest radiographic computed tomography showed a 6x6 cm tumor in the right lung field. There were low-density areas with septae inside the tumor. Bone scintigraphy showed extremely high uptake of (99m)Tc-HMDP in the tumor. After surgical resection and pathological examination, we concluded that the tumor was an extensively calcified benign hemangioma of the diaphragm.

We report a case of histologically proven intraosseous hemangiomatosis in which marked accumulation of pentavalent technetium-99m-dimercaptosuccinic acid (99mTc(V)DMSA) and technetium-99m-hydroxymethylene diphosphonate (99mTc-HMDP) was observed in the osteolytic hemangiomatous lesions.

A 14-year old girl had developed, at the age of 6, a swelling on the left shank. 4 years later, additional tumours appeared. 1990, at the age of 12, she had to be operated because of serious discomfort in the left ankle. The histological diagnosis was haemangioma plus enchondroma. At the age of 14 further haemangiomas developed and in early 1992 she had to undergo another operation of the left thigh. Histologically and immunohistochemically a Mafucci syndrome was diagnosed--a very rare affection belonging to the group of osteochondrodysplasia that usually goes with haemangioma and enchondroma. Radiological, scintigraphic and MTR findings are presented.

A bone scan and red blood cell scan in the rare epidermal naevus syndrome, associated with multiple haemangiomas of the bone and hypophosphataemic osteomalacia in a 20-year-old man are reported. The typical pattern of osteomalacia on the bone scan was associated with lesions of increased bone metabolism in the peripheral bones. The haemangiomas did not pool labelled red blood cells. Thus, the bone scan seems to be suitable for diagnosing the complete extent of haemangiomas in bone, but they could not be specifically proven by red blood cell pooling.

Incidental accumulation of bone-scanning agents in a noncalcified splenic hemangioma was observed on a bone scan performed for staging carcinoma of the prostate in a 68-yr-old man. This entity may be considered in the gamut of splenic activity on bone scans.

In searching for disease on skeletal images it is important to identify areas of increased activity and cold lesions, which are usually more difficult to identify. Focal photon-deficient lesions are due to metastatic disease in over 80% of cases. They may occur if the tumor is extremely aggressive, if there is disruption of the blood supply to the bone, or if there is significant marrow involvement, particularly in a vertebral body. Some of the common causes of a photopenic lesion are avascular necrosis, malignant bone tumors such as multiple myeloma, metastasis, radiation therapy, attenuation artifacts such as prosthesis or pacemaker, and early osteomyelitis. A case of hemangioma of the dorsal vertebra, a rare cause of photopenic lesion, is reported here.

Five hundred and eighty birthmarks were reviewed; 356 were hemangiomas and 224 were malformations. Bony alterations occurred in association with only 1 percent of hemangiomas, in contrast with 34 percent of patients with vascular malformations. These alterations in bone development were classified according to size, shape, and density changes. Hypertrophy and distortion were typical of lymphatic malformations. Hypoplasia and demineralization were characteristic findings in the extremity venous malformations. Destructive and intraosseous changes were more commonly noted in the arterial or high-flow lesions. Possible mechanisms of altered skeletal growth include mechanical, physiological, and developmental processes.

Three-phase radionuclide scintigraphy of the hand was performed on 116 patients. Normal and abnormal patterns for radionuclide angiography, immediate post-injection blood-pool images, and delayed scans (3-4 hr.) were established. Of 80 patients with normal circulation, 61 (76%) had equal radial and ulnar artery flow bilaterally, while in 19 (24%) either the radial or ulnar artery was dominant. Abnormal studies were grouped into three categories: suspected vascular lesions (Group I), pain of uncertain etiology (Group II), and patients evaluated before and after reconstructive surgery (Group III). The diagnosis was correct in 89% of the patients in Group I (34/38), 89% of those in Group II (57/64), and all of those in Group III (14/14). Three-phase scintigraphy of the hand yields significant information about perfusion and bone metabolism.

A patient with new onset seizures was found to have radiographic findings of a calvarial hemangioma. Because of the history, additional diagnostic tests were employed, which excluded cerebral lesions. Findings characteristic of hemangioma on blood pool imaging were felt to confirm the diagnosis.
