Magnetic Resonance Scan of an Encephalomalacic Brain Lesion Due to Concussive Shrapnel Wound

Hemangiomas are benign, slow-growing skeletal and soft tissue tumors that commonly involve the bony spine. When found in the spine, they are usually asymptomatic, but can sometimes be associated with local pain and/or neurological deficits. We report the case of a middle-aged Indian male with multiple hemangiomas involving almost all the vertebrae contiguously from C2 to S1 vertebral levels. These were discovered incidentally when a magnetic resonance scan was performed for backache. To the best of our knowledge, such extensive involvement of the spine has not been reported previously.

Transitory Effect

The patient, a 50-year old female had been suffering from right-sided head- and neck pain since she was 31 years of age. It started in connection with an indirect neck trauma. Analgesics were of little or no avail and operative procedures, including liberation of the greater occipital nerve (GON) ( n = 2) and decompression of the C2 ganglion/root, had only a transitory effect. At 42, a magnetic resonance scan of the cervical spine demonstrated a degenerated disk C5–C6, with encroachment on the foramina and the cord. At 42 years of age, a stabilization operation at C5–C6 (Robinson-Smith) alleviated her discomfort—only some motor complaints in the ipsilateral upper extremity remaining and only in the first 12–18 months.

The Brain

The article presents the results of treatment of aseptic meningoencephalitis in dogs of dwarf breeds. Diagnostics included a thorough neurological examination: assessment of mental status, ability to perform diagnostic tests, proprioceptive and postural reaction, the consistency and symmetry of cranial reflexes, including of pupil response to light and response to the threat, the presence of involuntary movements and forced poses, the intensity of the muscle tone and tendon reflexes. If an animal is suspected of having a brain lesion, other possible causes of encephalopathy were excluded. For this purpose, a General blood test was performed (to detect signs of inflammation, anemia); a detailed biochemical blood test (excluding renal and hepatic encephalopathy, indirect signs of the presence of a portosystemic shunt); if a portosystemic shunt was suspected, a blood test for bile acids was performed; when excluding all other causes of damage to the central nervous system. Magnetic resonance imaging of the brain was performed with contrast with the use of the drug OmniScan. During the magnetic resonance imaging, multiple foci were detected in all parts of the brain, including in the thalamus and trunk; including in some animals, foci that have a tendency to decay and form a necrotic cavity. It was established that before the start of treatment, animals had a wobbly gait, convulsive signs, a comatose state in some dogs, and weak visual reflexes. As a result of studies of morphological and biochemical parameters of blood in dogs, it was found that all the data obtained were within the reference values and did not have significant significance in the diagnosis of aseptic meningoencephalitis. Against the background of etiotropic and symptomatic therapy, positive dynamics was observed in patients with aseptic meningoencephalitis.

Mass Lesions

Central nervous system (CNS) lymphoma must be considered in the differential diagnosis of any immunocompromised patient with a solid brain lesion. In such patients, diagnosis can be made via a careful review of important signs, symptoms, and classic radiologic findings. While there is no single physical exam finding classic for lymphoma, the clinician must carefully evaluate patients for the presence or absence of findings that may suggest an alternative diagnosis. Such findings include the stigmata of endocarditis, symptoms suggestive of pneumonia, or additional non-CNS mass lesions. Additionally, several imaging modalities including magnetic resonance imaging, diffusion-weighted magnetic resonance imaging, susceptibility weighted imaging, and dynamic contrast-enhanced imaging can be useful in identifying this condition. While steroids can be helpful in reducing the disease burden and decreasing edema, they may also hinder diagnosis. Surgery may be indicated for either diagnostic or decompressive purposes; however, the mainstay of treatment is chemotherapeutic and immunotherapeutic agents with radiation reserved for refractory cases.

Klippel Trenaunay Syndrome

A female neonate was born with asymmetric lower limbs, the right leg appearing enlarged, with thickened, reddish-purple skin and ectasic superficial reticulum (figure 1A,B). Limb pulses were present and symmetrical. The girl’s family history and prenatal scans were unremarkable. Laboratory findings were within the normal range, except for a mild thrombocytopenia (90 000/μL), which spontaneously resolved during the next few days. A leg X-ray and the Doppler analysis ruled out the presence of calcifications and venous varices, respectively. Ultrasound showed significant skin thickening, with marked dermal hypertrophy and hyperechogenicity. Magnetic resonance showed circumferential thickening of the derma, with mild hypertrophy of some perforating vessels (figure 2). A biopsy of the right thigh showed capillary malformations on histology.Figure 1(A, B) Hypertrophy of the right lower limb, with large capillary malformation extending to the gluteus and the external genitalia.Figure 2Axial THRIVE magnetic resonance scan of the thighs’ proximal third, showing circumferential dermal thickening and inhomogeneity of the right leg’s subcutaneous tissue.QuestionsBased on the clinical picture and investigations results, which is the most likely diagnosis?Beckwith-WiedemannCLOVES syndromeKlippel-Trenaunay syndromeKaposiform hemangioendotheliomaHow can the diagnosis be confirmed?CT with PETLymphoscintigraphyGenetic testingNone of the above, the diagnosis is clinicalWhat is the mainstay of management?Conservative with follow-upPharmacotherapySclerotherapySurgeryWhich of the following complications can occur?ScoliosisGlaucomaUrinary and gastrointestinal bleedingAll of the aboveAnswers can be found on page 02.

A 56-year-old man with behavioural disorders and facial-brachio-crural right hemiparesis presented with a brain lesion studied with computed tomography, magnetic resonance imaging and brain biopsy, leading to the diagnosis of cerebral vasculitis. Hepatitis C virus (HCV) infection in a phase of activity, without cryoglobulins, was also detected. Brain biopsy, laboratory analysis and response to a specific therapy supported the diagnosis of central nervous system vasculitis that was HCV related.

Abstract OBJECTIVE Rosai-Dorfman disease is a rare benign histiocytic disease of unknown origin that arises predominantly in lymph nodes with generalized fever and malaise but can affect a variety of organs. We describe a case of isolated Rosai-Dorfman disease causing thoracic cord compression. CLINICAL PRESENTATION A 24-year-old man presented with progressive spastic paraparesis. A magnetic resonance scan revealed an anteriorly placed extradural lesion of the T4-T7 thoracic spine causing cord compression. He was systemically well with no other disease. INTERVENTION The patient made a complete recovery after a limited T4-T7 laminectomy and biopsy of the lesion. Repeat magnetic resonance scan at 6 months revealed a further posteriorly placed lesion at the T8/9 level. More extensive posterior surgery was carried out with subtotal resection of the lesion with pedicle screw fixation. Histologically, all specimens revealed fibrous connective tissue infiltrated by histiocytic cells with CD68 and S100 positivity, confirming a diagnosis of Rosai-Dorfman disease. CONCLUSIONS This is a rare case of isolated Rosai-Dorfman disease causing thoracic cord compression. It should be considered among the differential diagnoses of extradural cord compression. Radiological features and treatment options are discussed.
