Osteoid Osteoma

The symptoms and imaging are suggestive of osteoid osteoma. Osteoid osteoma accounts for 13.5% of all benign tumours. Most of those affected are young; approximately one-half are in the 2nd decade of life at presentation. The most common symptom is bone pain, which often worsens at night. The pain is thought to be mediated by release of prostaglandins, which helps explain the relief experienced after prostaglandin inhibitors such as NSAIDs such as aspirin.

Osteoid osteoma is a benign bone tumour usually present in the adolescent age group, typically as severe night pain that is relieved using salicylate analgesics. It is a cortex-based tumour. In general, a three-phase bone scan is positive with focal uptake and double density sign, that is, intense tracer accumulation in the central nidus and moderate uptake of tracer in surrounding reactive sclerosis. SPECT-CT is highly sensitive and specific in the identification of osteoid osteoma, particularly in the spine.

Pain should be described in terms of site, onset, nature of pain, radiation, aggravating factors, and relieving factors. Insidious onset pain is usually a feature of developmental conditions like Scheuermann’s kyphosis and benign neoplasms. On and off pain associated with sports and relieved by rest is seen in spondylolysis. Sharp shooting pain aggravated by coughing, sneezing, defecation, or Valsalva maneuver is a feature of a prolapsed disc. Continuous throbbing pain is seen in acute infective lesions. Dull aching pain with girdle pain and night cries are present in Pott’s spine. Night pain may also be seen in primary tumors/tumor-like conditions, e.g., osteoid osteoma. Inflammatory arthropathies are associated with morning stiffness.

Histology of the resected lesion by open surgery revealed an osteoid osteoma. After the surgery, the pain quickly resolved and the persistent joint limitation was treated by intensive physiotherapy to recover normal joint mobility, with good evolution. Osteoid osteoma is a benign bone tumour, affecting patients between 10 and 20 years of age, the majority of whom are male (1–4). Different localizations are possible and were described by Kayser et al in 1998, the most frequent localization being intracortical (about 75% of lesions) (4). These so-called ‘classical’ lesions generally involve the diaphysis or metaphysis of the long tubular bones (the tibia and femur being the most frequent) and consist of a radiotransparent ‘nest’ located in the centre of a fusiform cortical thickening (1).

A giant cell tumour (GCT) is one of the most common cause of solitary tumours in the patella. Characteristic image findings often show a lytic lesion that involves almost the whole patella with an ill-defined narrow zone of transition to normal bone. Cortical appearance is usually expanded and thinned, rarely finding a sclerotic rim and there is no periosteal reaction [12]. Chondroblastoma is also considered because of the solitary nature of the tumour, the age and gender of the patient, and lastly because the ossification of the patella is similar to that of an epiphysis or apophysis of a long bone. MRI findings characteristic of a chondroblastoma of the patella are of cartilaginous appearance, and edoema around the bony lesion and soft tissues [12]. Osteoid osteoma was also one of differential diagnosis, but based on the patient’s history, he did not exhibit localised pain during the night. The characteristic radiographic appearance is that of a lytic lesion with sharp margins with a nidus of small central ossification. But CT scan and MRI didn’t demonstrate a nidus and inflammatory bony lesion around nidus in this case. Aneurysmal bone cyst is also one of our considerations, but it is unlikely because the patient did not demonstrate a bulging growth of the patella. MRI showed no septations and fluid levels [12].

Osteoid osteoma (OO) is a benign, but painful bone lesion that usually affects children and young adults between 10 and 20 years of age [1]. The most frequent symptom is localised bone pain that worsens at night and is alleviated by nonsteroidal anti-inflammatory drugs (NSAIDs) [2]. The pain results from prostaglandin release by the OO nidus – a highly vascularised central region often surrounded by a fibrovascular rim and reactive sclerosis [3]. Complete and permanent pain resolution can be achieved through destruction of the OO nidus and adjacent periosteal nerves [1].
