introduction: atypical infratemporal fossa infections are rare and potentially fatal.   case report: a case of an aspergillosis localized in the infratemporal fossa and another case of tuberculosis of the infratemporal fossa originating from the maxillary sinus, is described. the first patient was immunocompromised and showed symptoms of facial numbness; whereas the other was an immunocompetent...

STUDY DESIGN Early diagnosis of vertebral infection (hematogenous or postsurgical) is necessary to choose a correct therapy and to minimize dramatic complications. All patients suspected to have vertebral infection underwent radiologic imaging and In-Biotin scintigraphy. OBJECTIVE Biotin is a growth factor used by many bacteria. The aim of our study is to use In-Biotin to diagnose vertebral i...

Cryptococcus neoformans is a significant fungal pathogen of immunocompromised patients. Many questions remain regarding the function of macrophages in normal clearance of cryptococcal infection and the defects present in uncontrolled cryptococcosis. Two current limitations are: 1) The difficulties in interpreting studies using isolated macrophages in the context of the progression of infection,...

Brain tubercluomas are a rare manifestation of mycobacterium tuberculosis infection usually resulting from hematogenous spread of the bacteria from a primary focus elsewhere in the body. A 29-year-old female with no history of pulmonary tuberculosis or signs of pulmonary infection presented with signs and symptoms of raised intracranial pressure. She underwent CT and MR imaging where multiple e...

Deep neck infections (DNI) have a propensity to spread rapidly along the interconnected deep neck spaces and compromise the airway, cervical vessels and spinal canal. The value of imaging lies in delineating the anatomical extent of the disease process, identifying the source of infection and detecting complications. Its role in the identification and drainage of abscesses is well known. This p...

We present the case of a 13-year-old patient who presented to the Emergency Department with low back and flank pain. Cross sectional imaging revealed paraspinal pyomyositis and epidural abscess. A detailed patient history revealed a recent lower extremity skin infection consistent with tropical pyomyositis. Review of this case shows the importance for recommending either contrast enhanced compu...

The well-established gold standard for imaging infection is scintigraphy with radiolabeled autologous white blood cells (WBCs). Indeed, 2 years ago, in a metaanalysis of all papers published in the previous 20 years on imaging techniques for the diagnosis of infection (1–4), the importance of WBC scanning in this field clearly emerged, with few exceptions. In particular, for the diagnosis of va...

Armillifer parasites, belonging to the Pentastomida subclass, are commonly known cause infection in animals, particularly reptiles. Although rare, cases of humans have been reported. Most asymptomatic or mildly symptomatic, with severe presentations being uncommon. Symptoms can vary depending on whether nymph is encysted actively dying, leading immune-mediated reactions. Diagnostic imaging find...

lipomatosis of the nerve, also known as fibrolipomatous hamartoma, is characterized by the infiltration of the nerve by fibro-fatty tissue. the affected nerve becomes thicker, and it simulates a mass lesion. lipomatosis usually affects the median nerve and lipomatosis of the sciatic nerve is extremely rare. magnetic resonance imaging (mri) is the key to diagnosis, and it is usually pathognomoni...
