“…Plexiform schwannomas are not visible on radiographs but have a hyperintense signal on T2 on magnetic resonance imaging, as seen in this case. 1 Many plexiform schwannomas observed in a patient at once may be classified as schwannomatosis; there is a higher association of schwannomatosis with neurofibromatosis type 2 than of solitary masses. 2 Although plexiform schwannomas have no mitoses and lack the potential for malignant transformation, pleomorphic nuclei are commonly seen on histologic investigation, although this was not seen here.…”

“…These masses account for approximately 5% of all tumors involved with the upper extremities and 2.8% of biopsied benign, soft-tissue tumors of the hand and wrist. 1 These lesions typically occur along peripheral nerves and/or along the volar aspect of digits, hands, or arms. They may be associated with neurofibromatosis type 2, although they may also occur sporadically.…”

Osteomyelitis is a challenging condition to diagnose and successfully treat. A clinician diagnosing osteomyelitis is reliant on relevant aspects of clinical history, inflammatory markers and radiological imaging such as X-rays, CT and contrast MRI. The confirmation of the presurgical diagnosis is made from microbiological analysis of the bone biopsy and/or histological analysis for features of inflammatory changes. An ultrasound scan is generally thought to have less value in osteomyelitis diagnosis due to its inability to interrogate bone. However, this investigation can be helpful in detecting the site and size of soft tissue collections secondary to osteomyelitis and the presence of any associated foreign bodies. We present a case where an ultrasound scan played a key role in supporting the diagnosis of osteomyelitis of the thumb in a dog groomer. This is the first reported case of hair implantation osteomyelitis presenting without a cutaneous sinus.

Plexiform schwannoma is an uncommon Schwann cell tumor, characterized by its multinodular growth with a plexiform histological pattern. Plexiform schwannoma arises from the soft tissues around the head and neck region. Few cases are associated with neurofibromatosis type 2 or schwannomatosis. We present a rare case of this tumor in a 25-year-old man, who presented with a discrete movable, deep seated nodule, associated with pain and tenderness over the spinal region, across the seventh cervical vertebrae with chief complaints of dizziness and vertigo for the last one year.
