Chloroma refers to the extramedullary proliferation of immature myeloid precursors occurring in a gamut of myeloproliferative and myelodysplastic conditions; acute myeloid leukaemia being the commonest. With non-specific clinical and imaging manifestations, it runs a high risk of misdiagnosis which may significantly affect the outcome of an otherwise treatable lesion. Also with these lesions heralding impending blast crises, awareness of the imaging findings becomes imperative. Imaging not only helps raise the suspicion but also guides further confirmation by demonstration of specific immunohistochemistry markers, ensuring timely institution of chemotherapy. In general, solid enhancing lesions in any haematological disorder could be chloromas, especially if multifocal with mass effect.

Erdheim-Chester disease (ECD) is a rare sporadic non-Langerhans cell histiocytic (LCH) proliferative disorder with systemic predilection. It usually affects adults in the 5th-7th decades of life and has non-specific clinical manifestations. Its suspicion is often heralded by the presence of characteristic radiological findings and subsequently confirmed by demonstration of CD68-positive xanthogranulomatous infiltrates on histopathology. Despite being a non-malignant entity, it might be fatal due to organ dysfunction. Imaging plays a key role in the diagnosis, management, and follow-up. Imaging findings are essential to establish the diagnosis, assess actual disease burden, and explore the aetiopathogenesis and therapeutic options to halt disease progression and associated morbidity.

Tuberculosis is ancient disease known to mankind. Diagnosis and management of spinal tuberculosis has immensely improved in last few decades. Imaging, particularly MRI, plays important role in diagnosis of spinal tuberculosis and its complications. Four common imaging patterns of spinal tuberculosis include paradiscal type, central type, Anterior subligamentous type, and posterior type. Imaging also plays important role in differentiation of spinal tuberculosis from its mimics, particularly pyogenic spondylitis, and metastasis. Radiological interventions, such as CT guided vertebral biopsy, and percutaneous drainage of cold abscess, are commonly used in management of spinal tuberculosis. Monitoring of therapeutic response is often based on clinical evaluation and imaging. MRI is most common imaging modality used. Signs of healing include bony ankylosis, resolution of marrow edema, decrease in contrast enhancement, and fatty change with in bone marrow. PET CT is recently evaluated for response assessment with promising results. This review summarizes pathophysiology, clinical presentation, imaging features, radiological interventions, and response assessment in spinal tuberculosis.

Background Traumatic spondyloptosis is defined as greater than 100% of traumatic subluxation of one vertebral body in the coronal or sagittal plane which usually causes the complete transaction of spinal cord. It is a rare but severe injury of the vertebral column. We present four unusual cases of traumatic spondyloptosis causing complete spinal cord transaction, which were operated upon successfully. Methods We reviewed the imaging findings of four patients with traumatic thoraco-lumbar spondyloptosis from our radiology database, who presented to our trauma centre

Hypoperfusion complex is an uncommon entity found on computed tomography (CT) of blunt trauma. It is more common in children compared to adults. Everyone should be aware of this entity to interact with clinicians to aid in triage and management of patients in view of poor prognosis. It is also important to prevent unnecessary laparotomies by confusing abdominal organ injuries. There are certain visceral and vascular findings described on abdominal CT that would alert the radiologist for this entity. This pictorial review should increase radiologists' awareness and recognition of the CT manifestations of hypoperfusion complex before an irreversible state of shock occurs in blunt abdominal trauma.
