We report the case of a girl with known large right-sided and small left-sided neonatal adrenal haematomas who underwent bone scintigraphy 23 days after birth for suspected osteomyelitis. The radionuclide examination showed uptake of bone tracer around the right-sided haematoma, but no abnormality on the left side.

To demonstrate the combined use of scintigraphy and ultrasonography (US) in differentiating osteomyelitis from bone infarction in sickle cell disease.. Two patients with sickle cell disease were examined with a combination of bone, bone marrow, white blood cell and/or gallium scintigraphy and US.. The scintigraphic studies demonstrated areas of suspected osteomyelitis at the distal femur in both patients and at the proximal right tibia in one of them. US revealed subperiosteal fluid collections in these areas. Aspiration guided by US established the presence of pus at the femur in both instances, which was successfully treated with the US-guided insertion of a drainage catheter and aspiration only, respectively. Thick blood, due to bone infarction, was aspirated at the tibia.. The scintigraphic studies were useful in locating all areas of suspected osteomyelitis. The role of US was to confirm the presence of a subperiosteal fluid collection and to guide aspiration, which can show the distinction between a haematoma and an abscess.

Orbital wall infarctions resulting in orbital and epidural hematomas are rare manifestations of sickle cell disease (SCD). We report orbital compression syndrome associated with an epidural hematoma and wide cephalohematoma in a 15-year-old boy with SCD. An infarcted orbital bone was observed on magnetic resonance imaging and three-phase bone scintigraphy with Technetium-99m methylene diphosphonate. The patient recovered completely without surgical intervention at the end of the fourth week. Prompt diagnosis and proper management are critical for complete recovery.

A 69-year-old man with common bile duct cancer and deep jaundice had complained of abdominal pain after percutaneous transhepatic biliary drainage. The laboratory workup showed reduction of serum hemoglobin level after the procedure. A 99mTc-hydroxy diphosphonate bone scan was performed for further evaluation of common bile duct cancer, and there was no abnormality of the skeletal structures. However, diffuse and hazy increased radiotracer uptake was detected on the liver. Follow-up contrast-enhanced 99mCT revealed hematoma and subcapsular hemorrhage of the liver.

Retroperitoneal haematoma is rarely described in the context of bone scintigraphy, as it is usually an incidental discovery on bone scan carried out for another purpose. We report a case of a right retroperitoneal haematoma detected on Tc-99m-methylene diphosphonate bone scintigraphy taken in an elderly patient presenting with a mechanical fall and a right acetabular fracture.

A patient with chronic renal failure and secondary hyperparathyroidism had iliac bone biopsy. The procedure was complicated by a soft-tissue hematoma, which had calcified. A 3-4-cm palpable mass was visible in the lower left abdominal wall. Intense uptake of 99mTc-HMDP corresponded with the location of the calcified hematoma in this patient.

Two cases of unilateral and bilateral periorbital hematomas occurred in patients with sickle cell anemia. The cause of periorbital swelling in these cases was found to be orbital and frontal bone infarctions, respectively, diagnosed by technetium Tc 99m medronate bone scintigraphy. To our knowledge, periorbital bone infarction, as a part of the differential diagnosis of periorbital hematoma and as part of the possible ocular manifestations in patients with sickle cell anemia, has not previously been described.
