“…4 Baastrup disease is relatively rare, and the radionuclide imaging of this disease has scarcely been reported, particularly through SPECT imaging. [5][6][7][8][9][10] The 99m Tc-MDP bone scan detected isolated spinous process nodular abnormal tracer activity, in addition to Baastrup disease, and similar images are seen for fractures, bone metastases, and other diseases. Therefore, SPECT needs to be combined with CT to improve differential diagnosis: a fracture line can be seen in case of a fracture, whereas bone metastases appear as bone destruction and soft tissue masses.…”

MDP SPECT/CT Demonstration of Baastrup Disease

We report the MDP SPECT/CT findings of Baastrup disease in the interspinal region of L4 to L5 in a 76-year-old woman with a history of lung cancer. Baastrup disease, also known as "kissing" spine, is characterized by close contact of adjacent spinous processes with resultant enlargement, flattening, and reactive sclerosis of apposing interspinous surfaces. Knowledge regarding the appearance of Baastrup disease on 99m Tc-MDP SPECT/CT is important to distinguish it from spinal bone metastasis.

“…Radiographs and CT typically demonstrate abnormal cortical contact, flattening, and sclerosis of the opposing spinous process cortical surfaces (Fig 7). At PET, mild-to-moderate FDG uptake is seen within areas of interspinal ligamentous degeneration and interspinal bursitis (47,48). Care should be taken to avoid mistaking these findings for spinous process metastasis, especially at other sequences as well (Fig 8).…”

Whole-body fluorine 18 fluorodeoxyglucose (FDG) positron-emission tomography (PET)/computed tomography (CT) is performed primarily for oncologic indications; however, FDG uptake is not specific for malignancy. Herein we focus on causes of increased FDG uptake in and around joints, as lesions in these locations are commonly benign. A combination of primary intra-articular processes and osseous processes that may occur near the joint space will be discussed. Causes of intra-articular and periarticular increased FDG activity can be broadly divided into infectious, inflammatory, degenerative, and benign neoplastic categories. A familiarity with the full range of these processes is important to avoid misinterpretation, in turn decreasing unnecessary follow-up studies, procedures, and treatments. Differentiation from malignancy is often possible on the basis of a different level of FDG activity, divergent response to therapy, or differing changes over time, in comparison with a patient's known primary cancer. Recognizing an intra-articular lesion location can also be critical, as intra-articular metastases are rare. In some cases, benign FDG-avid articular and periarticular entities have a specific appearance at FDG PET/CT and a correct diagnosis may be made without any additional workup. In most other cases, comparison with prior studies and/or additional imaging can afford an accurate diagnosis. This review is meant to introduce the reader to a spectrum of benign FDG-avid articular and periarticular processes that may be encountered at oncologic FDG PET/CT to increase confidence and diagnostic accuracy.

“…The morphological appearance and features on computed tomography (CT) or magnetic resonance (MR) images have been demonstrated [11][12][13][14][15][16]. The characteristics and incidence of this entity on FDG-PET have not been fully investigated, although there Lumbar spinous process FDG uptake are some case reports demonstrating localized FDG uptake between two adjacent spinous processes with Baastrup disease [17][18][19].…”
